2:12
NodeJS first you have to install the NodeJS after that you have to install the Angular then only you will be able
2:18
to install the Angular right so node is a package management library without the

35:00
postman the respected result will be display here it will be displayed now this result I want to display on the
35:08
table this result I want to display on the table so let me see how to do
35:14
this so back to my project what you're going
35:19
to here you can see there is a TS file here now you can see go to the material
35:27
uh material design you can see we have to do the coding part look like this here I just copy the
35:36
text all this I just copy okay here this is HTML part this is
35:43
a TS part the TS path i'm going to copy
35:50
this i'm going to copy these all things display columns is all this column headings what are the edings we need
35:58
uh pagination you have to implement the pagination all the things you just
36:03
copied back to my here you can see the student component our logic this is the
36:10
coding part so here I'm going to paste it that's the thing you have to write
36:16
okay we have to paste it okay so here you have after after you have pasted
36:24
uh this is not a error okay this is not an error
36:30
This is not error you point is here you have to click on here you have to add
36:35
that add the class just click it here there's a bulb symbol you click on it
36:42
you have to add the class this class will be added as you can see the class
36:47
has been added successfully see that's the thing you have to do right now here first line we explain display the
36:55
columns right we have display the column what are the columns you have to display to to the
37:01
table you can see you go to your back end student ID student name address
37:09
mobile and active so the same column we have to given here we have to
37:17
given here so first one should be the
37:22
student ID right student ID and this is like
37:28
this you can see if you go to the example you can see I already show the
37:34
example here student ID student name this is the
37:40
a we have to write it here you see student ID second one is a student
37:49
name student name after that what are the another column
38:01

38:07
mobile after
38:12
that active this active state just called as active so we have
38:18
a 1 2 3 4 5
38:24
That's it after that what you're going to do is here this one we have to do it as we
38:32
have any we have to call as any you have to load any data call any
38:42
that's it right so we have we are loading from the API here we are loading
38:48
the API request to we have given the data source the data do passing to where
38:57
here to load the data right we have to load the data that's the thing it will be we we are
39:04
going to do it right so here this one also you have to select this one to implement the class page in
39:10
enter the view child we have to call it here comma component okay so how to call
39:17
it here here you can see here if you go to the ts file they are
39:23
telling view child Okay component we have to call it a view chart so that is
39:29
a view chart okay uh the based on the documentation I have here based on
39:35
documentation view right that's the thing you have to create here the page you have to write this hold on the shift
39:42
key down shift key plus one right so
39:48
that's the thing you have to right now now these are the columns we have write list like
39:57
simply got to arrange
40:02
it make the
40:10
arrangement right perfect so these are the columns
40:15
so ID student name address mobile and act perfect i hope you guys understood
40:22
the things well uh these are the display columns of my database uh the table
40:28
columns display columns i hope you you understood so far uh in my next video
40:34
I'll be continuing the API uh request thank you for
40:41
watching hi welcome back in this video I'm going to connect the API
40:49
request so first what you're going to do is in order to connect the API request go to the app module.ts this file you
40:57
have to add that library which is
41:02
HTTP HTTP client HTTP client
41:10
module module so select here click on here if the class is not appearing here
41:18
what you're going to do is simply you have to write it
41:23
import so that import open and close bracket you have to copy
41:29
this module you have copy this module you have to add it over here after that what I'm going to do is here you have to
41:36
write single quotation it is reside on the angular
41:42
so angular
41:47
common slash
41:53
HD it will decide on over
41:59
here from right from I forgot to write the form right so if I implement that
42:04
here this error go away right sometime it's not uh sometime it will coming the
42:10
class if the class is not coming you have to write like this http client module from angular common htm it reside
42:18
on in this here common http right in order to
42:23
implement the API first you have to write it http client after that what you going to do
42:30
is you have to go to the student component this student component component our logic file here I'm going
42:38
to write the constructor so you write the constructor constructor you write the
42:47
private http
42:54
http client open and close bracket now
43:02
Here you have to implement the this class okay now we already we have the
43:07
add this class so add import the angular common http it's coming from that class that's it right perfect after that what
43:17
you're going to do is first we have to this is the API we use to view the records here this
43:24
is the API this API we have to call into our angular program to load the data
43:30
into the angular table so how to do the task you have to simply you have to
43:37
create the method which is a get all
43:42
student get all open and close bracket
43:50
here I'm going to type this dot http dot this is a get
43:59
request as you can see the API is a get request the same thing in angular also
44:06
you have to write this http get request you have to add the API request over
44:13
here within the double quotation mark you go to your Postman copy this
44:20
API paste inside here after that dot you have
44:27
subscribe your subscribe you have to get the values to the you have to write the
44:32
you have to write result data you write result data result data any you have
44:39
write any after that you have to write the arrow
44:45
function you have to open and close bracket here what you're going to here
44:51
you have to close it here here once you get the data from the API
44:57
it will be loading until uh it will be loading dot
45:03
subscribe subscribing until the load data loading after loader it will be passing the result data after that what
45:10
you're going to do is here in this data we have to where we have to pass it to the table so we source this dot data
45:19
source equal new this one right the meta meta table mean this
45:26
is the angular materialized table we have to passing the data
45:31
new data met data source what is the thing you are passing this API data this
45:39
API data is loading via the result data right once you given here this all the
45:46
data If you all the data via send button all the data will be loading it all the
45:51
data will be passing via this result data we have to pass into the our table
46:00
that's the thing right after that we have write this dot data source dot paginator we write
46:08
the page we need a pagination as well so the paginator equal this dot
46:16
Paginator you write paginator that's it after that that's the thing you have to
46:21
write perfect now if you have the testing purpose you have to test it you using the console.log you have to write is this
46:28
console.log This is our data we'll be check it whether the data is coming or not successfully through
46:36
the console let's comment this two let me check before you are passing the data
46:42
into the table we'll be checking whether it's parking passing the data is right or not right now let we can check it
46:51
right so before we checking what we are going to do is this is your table uh your method this method
46:58
you just copy paste inside this constructor if you paste inside the
47:04
constructor when the uh when the program is loaded this constructor get executed
47:09
right the constructor get in uh uh get loaded so you have to write this dot get
47:17
get all students right file save now let's go back to our angular
47:25
application it's loading
47:31
uh right now here you have here your table is coming but the we haven't do
47:37
anything else that's why it's blank table here the pagination all the things are there now let's file say uh here go
47:44
to the uh click on
47:52
this here you can see the console
47:58
here the data is coming successfully this data is coming
48:03
successfully here this data this data here student ID student name all things are successfully coming
48:10
here because you have tested when it's coming successfully or not now let's
48:15
it's coming successfully now it's subscribe to you remove the comments
48:21
right now we have to pass the data into the
48:26
table so here what's the data is coming here results data we are passing to the
48:32
data source and page it's a data source you can see the data source mean it goes
48:38
to the student component here student component m data data source so all the
48:44
data value will be coming here now we have to get it here so first one this is
48:50
one should be the student ID so this this
48:56
field what the field is this check this one uh you can go to the API again here
49:04
right click impact then you load the data here it's coming here the student ID student the same name you have to
49:12
give so the student ID you can the student ID student name and mobile this
49:18

49:24
ID ID after that this one should be the student
49:29
name student name after that third one should be the
49:35
student time ID uh address mobile active state right so here the same name we
49:41
have type so here we have to retrieve the value matt column def here right so
49:47
in the position also you same thing your student ID type it here student right so
49:53
this is the name the column name so student this one should be the
50:01
student name third one should be the student
50:07
address here also address okay you have to see here the
50:14
same name you have type address was the name you are given after here I'm going to give you as an address
50:21
ID here also the same name you have type it here also
50:27
address after that here also mobile here also mobile
50:36
setting element we have type as a mobile the final thing is active state
50:43
so we have we need one more column Copy this paste over here this one should be
50:53
active you can see active here this one also
51:01
active here also you have to make it as active that's it now let's file save all and back it
51:08
and check it here
51:16
so here we can found the error could not find the column my okay I have leave the
51:24
small mistake that's why it's not coming here this one here what I did here is the student
51:32
ID student name address mobile and active this all the things the TS file
51:38
this is not a heading not this heading okay we You have to give these names
51:44
okay the column names what are the columns of the database columns okay
51:50
what are the this display columns mean this display columns which mean is what are the display columns in your database
51:57
table okay that's table name you have to give it here second one student
52:04

52:09
address mobile that's all thing student
52:15
address mobile this one should be
52:21

52:55
successfully I hope you guys understood things well I'll see in my next
53:03
lecture hi welcome back in our last video we saw how to load the records we
53:10
saw how to load the record uh in this video I'm going to talk about how to add
53:16
the records so you already made the design of the registration
53:21
form now let's see go back to our uh project go to
53:29
the student compound.ts file here we have to write the logic
53:36
so this one should be our display the records now I'm going to do the thing is
53:41
I'm going to create the here I'm going to create the variable now here first
53:48
one should be the student name student name the student ID should
53:54
be we have in back end we have create as auto increment so that we have to create here as student name you are going to
54:00
add the so you get the field student name colon we have to give the
54:08
appropriate data type which is a string so string data type you have a you have
54:13
to write like this you have to create the variable this variable name this appropriate data type you have to the
54:20
data we have write is just a blank right this this write this data you have to giving giving into the your phone your
54:28
phone you are typing on the that data the data it will be passing here the
54:34
second data which is a address that also string
54:43
Okay that also the strata should be the string data type which is address also
54:48
string data type after that mobile which is a integer you write
54:56
mobile it's a number you write on angular which is a number equals zero you have to write
55:04
zero after another one is active the active state which is a boolean type
55:11
true and false so you write the variable boolean two default it is true to make
55:19
the changes it will be it will be false and that's it that's the thing we have created over here that's the thing we
55:26
have created over here perfect now let's we have created the variable
55:31
successfully now what you're going to do is I'm going to go to
55:37
uh create the function which is a registration function before that we have to go to this all the variables we
55:44
have set into the form so your form this is your form
55:49
input field this is the input field we have to create the input fields here this is the input field we
55:56
have created so the math input here what you're going to is you have to write it
56:04
the angular ng model you have to write the
56:09
ngmodel you have to write ng model so here ng
56:14
model you have to write equal student
56:20
name student name right so what's the name you are typing on the
56:26
student input field this that particular name this particular the same name you have to switch this
56:34
name it is it will be display over here right okay what is the name you're
56:40
typing What the name you are typing on the input field this name will be
56:45
storing ng model it will be storing here this ngm model the name it should be storing the ngm model after that you
56:52
have another component you have to write it here write ng model option
57:02
options uh equal you have to write
57:09
standard stand
57:16
alone all right engine model options
57:24
equal stand right so now uh when we load the
57:30
form what is the value you're typing imagine you are typing
57:35
John this John name will be storing this ngm model right it will be passing to
57:43
the ts file over here right that's how we have we'll be able we have to pass in the data right
57:50
the ngm model right so the same thing we have to do the second one also the
57:57
address also we I just copy
58:02
this and here address field after the input we have to paste it over here this
58:08
one you just named it as address here the address is pop up it's
58:14
coming from here from the TS file address right third one is a mobile
58:22
the same thing just Copy it paste it over here third one is
58:29
a mobile that one is a mobile right you
58:37
have some mobile after that our
58:42
uh fourth one is a fourth one is a active this is active
58:48
this is active here this active you have to uh put it here the selection here
58:54
required after that we have to write here
59:01
class ng model this one should be active select active that's it that's
59:08
the thing you have it here the selection active right it will be what is the
59:13
selection you have if you have select as true it will be true will be storing here if you are select false it's false
59:19
will be storing here right so this all John address all the things what What
59:25
what the value you are typing on the fields the fields value are storing here the ngm
59:30
model the ngm model will be passing to this ts file here student name what's
59:38
the name name coming from the form it be store what's the address coming from the student this
59:43
form mobile and active that's it that's how storing the
59:49
value after that we have a registration button so we have the
59:55
registration button registration button so you go to
1:00:02
here here we have a save button save you have to write
1:00:07
a one click okay
1:00:13
click this one you called as we just called as
1:00:19
register type your register the register method when you click the save after enter all the values click save button
1:00:26
it calls the register function register function is where it is in the TS file we have create the
1:00:32
register function
1:00:39
register right now we have retrieved the values
1:00:45
okay so here so all the values are coming from the form this value we have set into the database API fields right
1:00:53
so database API fields mean so we are go through our database uh postman you can
1:00:58
see here these are the values on your back end application these are the values so we have tested so here ID
1:01:05
should be auto increment once you add the record ID should be auto increment so we don't need the ID rest of the
1:01:11
fields you just copy it here just copy it control C copy and paste it here right here this
1:01:20
is your postman you can see postman you just copy and paste it simply I'm I'm
1:01:26
telling you the easy way to make the application you have to align correctly here like this okay now what you're
1:01:33
going to do is this is your form field here when you add the record you are giving your own data
1:01:39
here okay here when you add the record here when you post the record you post the record the body tag here you are
1:01:45
giving your own data okay the same thing here what you're
1:01:51
going to do is you have to give the instead of giving your data you just enter the data what the data you're
1:01:57
typing on the form that data you have to given here these are the your back end
1:02:04
field these are the fields you are setting here the postman these are you are setting as a back end the back end
1:02:10
application you are setting okay here these are the fields you are setting the back end save d we already show these
1:02:17
are This how we have the name you have to set it the same name you have given here
1:02:25
right that's why I just copy that copy from here right now here you have to
1:02:33
pass in which data we have to uh add into that uh database your form data
1:02:40
that is that form data you have to pass into the API value so the form data is
1:02:46
once you enter the name address mobile number and active what
1:02:52
happen I already show the flow it will be storing here it's simply passing to
1:03:00
the TS file over over here and this all the values will be passing to here so
1:03:06
you have to write how to get them this dot student name you have write this dot
1:03:13
student name right student name right student name comma
1:03:24
uh what's the problem sorry what's the problem here is okay I just cut off uh
1:03:30
control x to cut off what's the problem here is you have to write the you create the variable which is a leg variable
1:03:36
table this also the JSON format you have to add the recording as a JSON format
1:03:42
you have to write you have to create the create as a JSON format that's why it's getting the error okay you have to
1:03:48
create like this way right you have to create like this way okay so here you
1:03:54
have to create a variable let body data equal you have to create a JSON format
1:04:00
the JSON format I I already show once you add the data The post method here I
1:04:07
post method I have accented here open bracket and close bracket here these are
1:04:13
JSON format you have to sending the value so here also we have to write it's a
1:04:20
JSON format this JSON format inside here you have to write here so one name this
1:04:26
is fine second one should be address this dot address okay this is
1:04:33
the API which address you have So uh this uh here we have to pass it the form
1:04:39
address third one is a mobile the same thing is just comma copy this here we have to write
1:04:46
this mobile so we have just mobile after that final one should be
1:04:54
the active selected that's it that's the
1:04:59
thing now this data is this form the form data we have to assign to the relevant field of the
1:05:08
API uh values and sending to the API URL
1:05:13
okay so API URL we have to send it so we have to what is what is the URL what I
1:05:20
did here is this is the URL we are g okay student save the student save right
1:05:26
student save okay so here you have to go here simple you have to here go this
1:05:32
things the get all function is save API just
1:05:40
save here you have to save the record okay this is a force method you try to
1:05:46
post method and save the record right so what you're going to do is what happen is this is the API so API just copy we
1:05:53
already we tested this all the API you no need to test it again right So let's
1:05:59
what you're going to see here this is the post request so post request
1:06:06
post this http dot
1:06:12
post write open and close bracket inside here we have to paste
1:06:19
it right it's a post request right okay when you are uh add
1:06:26
the records we have the post method we already we already discussed about these all things when you are doing the back
1:06:32
end So we no need to discuss comma you have to write
1:06:40
body data body data mean what is the thing this is the API which data you are
1:06:45
going to passing this all the form data we are passing like this thing if you are writing here the
1:06:52
postman here this body this is the body this all the body we are passing to here
1:06:57
the same thing here we have do it here as this all the body data same like a postman you have to pass
1:07:04
into here right so after that comma you
1:07:09
have to write it another thing of springboard uh if you are doing as a back end
1:07:14
springboard you write rest type I'm going to give here as
1:07:23
text response type you have to give as text right that's it now after that dot
1:07:30
subscribe you have to subscribe until add the records to the database After
1:07:36
that you have to write you have to if the record this data is added succeed or
1:07:42
not we have to passing as a result data result
1:07:50
data dot n right you have write here you have write
1:07:57
the arrow function open and close bracket right here I have to get it
1:08:05
two lines that is a for right after that what I'm going to do is right now here
1:08:11
the data is successfully added the data is successfully added we
1:08:18
have write it here art you write here uh art you write
1:08:25
alert message record student register success from
1:08:33
Student registered registration
1:08:41
successful right perfect now let's file save
1:08:49
all now let test whether it's working fine or not right now what you're going to do is I'm going
1:08:55
to first John address
1:09:00
India mobile number I'm going to give some mobile number active state and lead group click save button student
1:09:08
registration success it's working fine click okay now let's go back to here
1:09:15
API which is student uh we have tested
1:09:20
get let's set Uh first you have tested here after that
1:09:26
you have to test the table right so you test out here get all this tested here
1:09:31
newly added record will be here the newly added record will be passing successfully john India this all the
1:09:39
record will be successfully added right now we no need to check once we add the record we don't need to check on the
1:09:45
postman whether it's added or not we will be able to test it on the table
1:09:50
right so I have uh tell you the two ways that's why I will I will be show you
1:09:56
this this also so here you can test it because I already done the table part as
1:10:01
so how to test it here you have to call simply after the records here get all student you have to
1:10:08
call it over here okay here this dot sorry get
1:10:14
all this dot you have to write this you have to use this okay this form this
1:10:19
mean this form okay and angle you have to this right now you can see here here
1:10:26
newly added record will be here now if you add another record so after add the record I want to clear this field that
1:10:34
also must so how to clear the in angular write this dot the form names
1:10:41
This one student name equal you have to write like this
1:10:48
by double quotation how does this dot
1:10:55
address equal clear
1:11:01
restart mobile equal
1:11:10
clear right sorry mobile is not a clear it's not string it's a boolean right so
1:11:16
after that you have to clear this all things after that active state is just a boolean so that we have a default value
1:11:23
should be true you have to write a true that's that's the Okay okay right the
1:11:30
form will be loaded again and all the value must must be clear so file save
1:11:36
our back to our application you can check it i'm going to add another value which is a
1:11:41
PA address India phone numbers or something like that back to state row click hit save
1:11:50
button here shouldn't register successfully click okay here all the fields should be clear yeah it focus
1:11:56
yeah yeah uh the final record will be PA India mobile number and district it's
1:12:04
working perfectly well I hope you guys you understood the things well I'll see
1:12:09

1:55:05
your project go to your compass component here we have the button you
1:55:12
have to go above there's a button here save after that we have a clear button here this method you just copy this one
1:55:20
paste it here you have to make this one as a clear you have to call as clear
1:55:26
so if you make the function here you just copy this one simply you have to go to the student component TS file this TS
1:55:35
file right so I'm going to make the function
1:55:41
here open and close bracket you no need to do anything else you just go to get
1:55:46
the code from somewhere else here the update also after update the record the form has been clear so the same quotes
1:55:53
you just copied this all the code you just copied copy it okay we have to clear
1:56:00
everything table and everything clear you have to clear it put it here that's
1:56:06
it the table if you have clear mean totally the form is clear the table is clear now all the form data and
1:56:13
everything should be clear if you click clear but if you accidentally click
1:56:19
update also you can clear all things should be perfect that's the thing you have to write file now let's back to
1:56:26
application here you click accidentally click click the application
1:56:32
accidentally now I don't need to write anything click on this clear it will be
1:56:38
clear application is clear perfect now I want to make
1:56:44
this here in between this header and form we need a small space between that
1:56:50
so how to handle this one simple you have to handle it go below i'm going to
1:56:56
break the break statement so
1:57:04
break let it put the break file save bring back the
1:57:12
application simple right now here we have a small smelling mistake we have to
1:57:18

1:57:33
make it as another things you have here you can see the light you can make it as
1:57:38
dark and see whatever that's another thing as a dark style you can make it as
1:57:44
dark this one also dark this one also the dark control S to
1:57:50
save bring back to the application here it's look like this so
1:57:56
the rather than this that is a beautiful okay you can have a nice look here okay
1:58:02
this this it is look beautiful the light so I'm going to make it as uh you have
1:58:08
