[0:00] hey guys welcome back so guys in this
[0:02] video we are going to learn the complete
[0:05] rest API in larl 11 version so guys I
[0:09] have already installed a fresh laral 11
[0:11] application here and and also served the
[0:15] application at Local Host 8000 which is
[0:18] running over here okay so now guys let's
[0:21] get started so let's open our project in
[0:23] our editor so I use vs code editor so
[0:27] first step uh after installing your
[0:29] larel project
[0:30] let's install the API also so let's open
[0:34] the terminal and click on new terminal
[0:36] so before installing I just want to show
[0:38] you few things like here routes so in
[0:40] this routes you see you don't find
[0:42] api.php file and inside your database
[0:46] you don't find few migration about the
[0:48] API personal access token and also guys
[0:52] about the model so in the model user.php
[0:55] you don't have a trade called has API
[0:59] token okay so guys now let me
[1:02] just get started with installation PHP
[1:06] Artis install colon API hit enter so
[1:10] your installation
[1:18] starts so guys our installation is
[1:21] completed and here it's asking a
[1:23] question like new database migration has
[1:25] been published would you like to run all
[1:28] the pending migration files yes or no so
[1:31] right now we'll give no guys because we
[1:33] want to see our database connected or
[1:35] not and here you see API scaffolding
[1:39] installed please add the has API token
[1:43] trade to your user model okay so make
[1:45] sure you're copying this now let's
[1:47] minimize the terminal and first let us
[1:50] go to your app model user.php inside the
[1:55] user model we have to add this has API
[1:58] token
[2:00] so let us give as use now you can copy
[2:03] this at the last of your use inside the
[2:06] class user model you have to add this
[2:09] has API token perfect so now guys uh we
[2:12] have added the has API token and now
[2:15] let's move in the migration so database
[2:18] migration you find the new table about
[2:22] personal access token okay and also
[2:24] you'll see a new file inside the routes
[2:28] api.php
[2:29] cool so now guys let's migrate that so
[2:33] before migrating please check do you
[2:35] have connected your database or not so
[2:37] yes I have connected here using MySQL
[2:40] and larel 11 database so now guys let's
[2:44] hit the command PHP rtis migrate hit
[2:47] enter and your table is
[2:51] migrated now let us get back and see do
[2:56] we have a personal access token table
[2:58] here so let's refresh so guys here you
[3:02] see we have a personal access token
[3:04] table okay so now so first step guys we
[3:06] are going to start with the API CED
[3:09] operation with an example of products so
[3:11] let's create a migration file named
[3:14] products the HP Artis make colon
[3:19] migration
[3:20] create products table hit enter and here
[3:25] migration is created now you can go to
[3:28] database migration and the last and now
[3:32] let's give the fields so we'll give a
[3:36] string the product
[3:38] name then the product price and one more
[3:42] field let's add that as a medium
[3:48] text text function which will be
[3:52] description okay and now let's push this
[3:55] table into our database so PHP Artisan
[3:59] my
[4:00] hit enter it's migrated now you can find
[4:03] that products table Let me refresh the
[4:06] table here okay products table cool so
[4:09] we have migrated it now we can get back
[4:13] and let's create the model so PHP
[4:15] artison makeen model the model name will
[4:18] be product hit enter so our model also
[4:23] is created product.php let me close
[4:27] this and go to app model your
[4:31] product.php
[4:33] perfect let me just zoom it so first
[4:36] step guys we will declare the table like
[4:38] product table equal to your table name
[4:42] products is the table name and then
[4:44] protected dollar
[4:47] fillable will be all the fields so what
[4:51] are the fields you can just copy from
[4:53] your migration
[4:55] file that is named description and price
[4:59] let's close
[5:02] name
[5:04] description
[5:06] price that's it and now let's create One
[5:09] controller so PHP Artis make colon
[5:13] controller and I want to create this
[5:16] controller inside a API folder API SL
[5:22] product controller hit enter and your
[5:26] controller is created so you can find
[5:28] that in app HTTP controller uh API
[5:31] folder inside that API folder you find
[5:34] your product controller cool so now guys
[5:37] let's begin with creating the functions
[5:39] like public function the function name
[5:42] index function and here is a typo so in
[5:46] this index function we will get all the
[5:48] records of the product so before getting
[5:51] the records we have to create the API so
[5:54] let us go to our routes api.php and here
[5:59] let's let begin so first step guys we
[6:01] are going to create a route using API
[6:04] resource route okay so now guys let us
[6:08] give
[6:09] the URL so creating a route products and
[6:13] let's mention the
[6:15] product controller colon colon class so
[6:19] make sure you're importing the class
[6:20] guys which is already imported
[6:23] automatically and now guys we can uh
[6:25] check the route list for this product so
[6:28] let me open the terminal PHP Artisan
[6:33] route colon list hit enter so let's move
[6:38] out the top and here you see the API
[6:41] part okay so this will be our complete
[6:45] API route so now guys we can just follow
[6:49] this and create the complete
[6:52] functions so let's move inside the
[6:54] product
[6:55] controller copy
[6:57] this create for the store
[7:01] and for the
[7:06] show and
[7:09] update and then
[7:14] destroy that's it so now guys let's
[7:16] begin with the index function so first
[7:19] let's create a variable called
[7:21] products equal to your product model
[7:24] colon colon get function okay so getting
[7:28] all the product data
[7:30] and import the product class so it's
[7:33] imported here guys and now let us return
[7:36] this in jsn format so first I will check
[7:40] if there is
[7:42] records like
[7:44] yes
[7:47] else so if a record is available then
[7:50] show else you can
[7:52] return response function in JSO n
[7:58] format and reply 200
[8:01] here and give the message
[8:05] as um no
[8:09] record available okay so if the record
[8:13] is found then we are going to return the
[8:16] Complete product data so how are you
[8:18] going to return guys we will be using
[8:20] the resource part so let me just a new
[8:24] terminal and create a new resource PHP
[8:28] Artis
[8:30] makeon resource
[8:33] the product resource okay hit enter and
[8:38] your resource will be created so you can
[8:40] find that in the app HTTP directly
[8:44] resources folder will be created and
[8:46] here is your product resource so guys
[8:49] this resources is used to respond in
[8:51] Json format okay so here you see Json
[8:55] resources it uses so guys now you can
[8:58] use this
[9:00] product resource so you are sending
[9:04] multiple data so you have to use in
[9:06] different way like just return product
[9:09] resources colon colon
[9:11] collection function and inside this you
[9:13] paste this product variable directly
[9:16] okay so whatever data you have in this
[9:19] you can access each column so before
[9:22] that let me import this class okay we
[9:24] have imported and now guys all the
[9:26] column Fields like name description and
[9:29] price at this product you can access in
[9:31] this product resources so right now you
[9:34] see here that it's returned directly
[9:37] parent to array so instead of this you
[9:39] can return in this format
[9:42] also like the
[9:45] name of dollar this of name okay so same
[9:51] way guys you have to change for the
[9:53] description
[9:56] description then price if if you want to
[9:59] take the created at column so you can
[10:02] take it same way created
[10:06] at
[10:08] Price description and if you want to
[10:10] give name or else
[10:13] product name so anyhow it depends on you
[10:16] so this will be the response output okay
[10:19] okay so let me just keep it name itself
[10:22] and we can get the ID
[10:25] also done so guys the difference is here
[10:29] you can can manage only like what Fields
[10:31] you want to show or else if you want to
[10:33] show complete thing you can just keep
[10:35] the same okay so guys I will prefer
[10:38] using like this so now let's get back
[10:41] and yep so guys let us test this API
[10:44] like this index function part so let's
[10:47] go to our api.php and to test this API
[10:50] I'm using a postman software so let me
[10:53] just open so guys this is a postman
[10:56] software which I have installed so now
[10:58] guys let's make make a new request here
[11:00] just click on this plus icon and here
[11:02] your request sends so now guys let us
[11:04] copy the API get back and by default you
[11:08] have to give API and then products so
[11:11] what is the complete URL guys let us go
[11:14] to our browser just copy this Local Host
[11:17] 8,000 and paste
[11:19] here let me remove this extra forward
[11:22] slash and let's send the request so if
[11:25] you send so let's see what happens now
[11:28] so here we get at the error guys like
[11:33] raw so internal server error which is
[11:36] telling the collect function does not
[11:40] exist so it's not collect it's
[11:42] collection guys so let's go back to
[11:46] our index function and tell
[11:49] collection and now get back send the
[11:52] request and here you see by default data
[11:56] has come okay now you can click on this
[11:58] pretty so here you see in the object
[12:01] data you are getting this empty array so
[12:04] guys here it's not able to check like it
[12:07] has data or not so you can use just
[12:09] count function if it is greater than
[12:11] zero then you have to return this else
[12:14] return this so now get back again send
[12:17] the request so here you see the message
[12:19] no record available and the status is
[12:22] 200 so you can see at this okay so now
[12:26] guys uh let us get back and and start
[12:29] with inserting the record using the API
[12:32] so it is very simple guys just use a
[12:34] simple request here get the request
[12:36] dollar request and do the validation
[12:40] first request of
[12:42] validate function and use the name field
[12:50] okay this will be your input field value
[12:52] and what will be the validation it is
[12:56] required and it's going to be a string
[12:59] value and then Max
[13:02] 255 same way for
[13:05] the price will be integer and you can
[13:08] remove this
[13:10] Max so this will be the price and for
[13:13] the
[13:15] description it is required string and
[13:17] Max should not be there okay so now guys
[13:21] you can get started with inserting the
[13:23] record into your model I mean product
[13:25] table so let's use product model colon
[13:29] colon create function in Array format
[13:33] and you get all this each Fields so let
[13:37] me just copy and paste here and insert
[13:40] this just get the
[13:43] request
[13:44] of name okay so this will be a name
[13:48] description so you have to just paste
[13:50] that let's paste here paste it so my
[13:55] input request description and input
[13:58] price so once product is created you
[14:01] have to send let's response so return
[14:04] response function in JS n
[14:08] format in
[14:10] Array 200 and here array will be like
[14:15] message
[14:17] of product
[14:20] created successfully and also you can
[14:24] respond the data guys which
[14:27] is the
[14:30] dollar product equal to Dollar product
[14:33] okay and here you set the
[14:37] data instead of sending the complete
[14:39] model we want to send our format data so
[14:42] which is the product resource so let's
[14:45] get back on this let's copy the product
[14:49] resource
[14:51] and make as new product resource
[14:55] function okay so now guys let's get back
[14:58] and create a product record so let me
[15:02] just copy this complete API and paste
[15:05] here so guys to create or insert the
[15:08] record you have to use the same route
[15:10] which is shown here let me just show you
[15:12] in
[15:14] the route list so here you see guys that
[15:17] is about the post request which is
[15:19] product. store it goes to the store
[15:21] function and this is the API so using
[15:24] post method and the API stat so now guys
[15:27] let's get back to our Postman
[15:30] and yep so this will be the API and it
[15:33] is a post request so let us select that
[15:35] post method and now guys let's go on the
[15:38] body Tab and here you have to select
[15:40] with form data or raw data okay so now
[15:44] guys let's add the fields so make sure
[15:47] this raw data which you are entering it
[15:50] should be in jsn format so select the
[15:52] jsn format here first and then you can
[15:54] work on it so now guys let's add the
[15:57] fields like name colon and here I'll
[16:00] give null and the field
[16:05] description description colon null and
[16:09] finally the field price colon
[16:13] null okay so now guys let us uh just
[16:16] click to send the request what happens
[16:18] now if you click
[16:20] Send uh here you get an error like let
[16:23] me just click on preview so here you see
[16:25] guys that is it is showing the main page
[16:27] homepage so I think it's not able to
[16:30] handle the validation part so let us get
[16:33] back and move at the store function at
[16:37] validate code so instead of this
[16:40] validation we'll be using a validator
[16:42] method so let's create a variable called
[16:45] validator equal to your
[16:49] validator class colon colon make
[16:51] function and inside this function you
[16:54] have to pass dollar request of all
[16:57] function and then use array and give all
[17:00] the input Fields so here you just copy
[17:03] and paste the
[17:05] fields and yep so now you can remove
[17:09] this now let's copy this
[17:14] validator
[17:16] if
[17:19] validator fails
[17:22] function then just return response
[17:26] function in JSO n
[17:29] format and the error will be
[17:32] 422 so in this uh you can send the
[17:36] validator messages so let me copy this
[17:39] variable and mention that error then
[17:43] Arrow function dollar validator of me S
[17:46] AES messages function okay and if you
[17:50] want to mention like the
[17:55] message
[17:57] uh all
[17:59] Fields fields are
[18:02] mandatory okay and now guys uh import
[18:05] this valid data class so class import so
[18:09] here you select with eliminate support
[18:11] fets valid data let's click on it and
[18:14] yep so you can just
[18:16] move and update that valid dator okay so
[18:19] here our valid dator is imported perfect
[18:23] so now guys let's get back to our
[18:24] Postman and send the request again so
[18:27] here all the fields are empty right now
[18:30] let's click to send the request so here
[18:32] you see all fields are mandatory the
[18:34] message is and the error inside that it
[18:37] is showing name field is required
[18:39] description required price is required
[18:41] so let us add the product like
[18:45] apple and this is Apple
[18:50] description and I will keep the price
[18:52] empty let's send a request so you see
[18:55] again that it is asking for the price
[18:57] field and now if I give
[18:59] like 250 and let's click to send the
[19:02] request so here you see the product
[19:05] created successfully and this is the
[19:07] data guys okay which is just shown only
[19:10] whatever Fields you want so now guys let
[19:12] me just show you in the database whether
[19:14] it is stored or not perfect so here you
[19:16] see guys our record is stored and now
[19:19] guys let's get back to the editor and so
[19:23] we have done with the create product and
[19:25] now let's move on to view the product I
[19:27] mean fetch each product so for that
[19:30] let's get back to the api.php and this
[19:33] is the API resources guys and according
[19:35] to this to get the data one data you
[19:38] have to use this route so which is
[19:41] coming via show method so here is the
[19:45] show method with the product product ID
[19:49] and using a get method okay so what you
[19:51] have to do you have to use this product
[19:54] product variable inside your controller
[19:56] so let's copy this product and get back
[19:58] inside your show function and here
[20:02] provide the model name product and then
[20:06] the product variable so make sure this
[20:08] variable is same as provided in your
[20:10] route list so this is the variable guys

[25:24] again with the pricing like I will keep
[25:26] 50 send the request and here you you see
[25:29] the data is price 50 so guys we have
[25:32] done with the updation part also cool so
[25:35] now guys let's begin with the last
[25:37] option that is destroy which means
[25:39] deleting the record using the API so let
[25:43] us get back to our code and this is our
[25:46] public function destroy function and in
[25:48] this destroy function how you can use
[25:50] please check out your route so here you
[25:52] see it is using a method delete and the
[25:55] API is same like as we edit upd dat so
[25:59] same way you can delete Also let's call
[26:01] the product model P doct product model
[26:05] dollar
[26:07] product so from where are you copying
[26:10] this variable product so here is the
[26:13] product variable guys just copy this and
[26:15] paste here and it going to the destroy
[26:18] function so now let's use this
[26:21] product and use delete
[26:24] method that's it so this will delete the
[26:27] record and then you have to return a
[26:29] message so let me just copy from above
[26:32] and paste here and here we don't need to
[26:34] show the data because we have deleted it
[26:37] so let's mention the message as deleted
[26:41] successfully okay so now guys uh let us
[26:45] get back to the postman and let's copy
[26:48] this
[26:49] API get to the new request paste it and
[26:54] please select the delete method so using
[26:57] this delete method and sending the
[27:00] request with the ID3 I want to delete
[27:03] the ID3 data and now let's click to send
[27:05] so once you click to send it will delete
[27:07] the record so let's click on send so
[27:10] here you see product deleted
[27:12] successfully and if you try to get the
[27:14] record with the ID3 you'll not be able
[27:17] to get because it's already deleted so
[27:19] let us see that let me just move to the
[27:21] third tab here which is using a get
[27:24] request and this is the ID3 let's click
[27:27] to send so here you see we have got the
[27:30] response guys and let me just preview
[27:32] here you see that 4 not4 perfect so here
[27:35] you see that 4 not4 means it's not found
[27:38] so ID3 is not found but guys this is not
[27:41] the correct way to show the output
[27:44] because it is a API request so for that
[27:46] guys you have to just add a simple code
[27:48] inside your uh go to bootstrap inside
[27:51] this bootstrap app.php and inside this
[27:54] app.php with exceptions so let's go to
[27:58] the larel documentation on error
[28:01] handling so here I found that how we can
[28:04] skip this so just copy this code guys
[28:07] and paste inside this exception part
[28:10] okay and also import this not found HTTP
[28:14] exception and also the request classes
[28:16] so here it is let us just copy this
[28:19] contrl C and import or paste at the top
[28:23] that's it now done so guys let us close
[28:26] this app.php and get back to your
[28:28] Postman and send the request again let's
[28:31] click to send so here you see message
[28:34] record not font cool so guys let us just
[28:37] get to the first uh request that is
[28:39] fetching all the products so let's fetch
[28:42] so here you see that on this request you
[28:45] have got all the products so ID one and
[28:47] id2 that is Apple and mango product
[28:50] third product is deleted
[28:53] okay so guys we have successfully
[28:55] completed with the restful API crowd
[28:58] operations using the API resource route
