Updating Data to db in Laravel - php

Question

I have a problem while updating data to the database in laravel. Normally the data gets inserted to the database with store function(POST request). But the update POST request doesn't make a update to the database. And my code is
routes.php
Route::resource('Customer','CustomerDetailController');
Route::get('/', function () {
return view('welcome');
});
Model
CustomerDetail.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class CustomerDetail extends Model
{
//
public $table = "customer_details";
protected $fillable = [
'Name', 'Contact_Number','Address','NoOfCans','Price'
];
}
Controller
CustomerDetailController.php
<?php
namespace App\Http\Controllers;
use App\CustomerDetail;
use Illuminate\Http\Request;
use App\Http\Requests;
class CustomerDetailController extends Controller
{
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
//
$Customers=CustomerDetail::all();
if($Customers){
$response = [
'msg' => 'Customer Found',
'Customer' => $Customers
];
return response()->json($response, 201);
}
else {
$response=[
'msg'=>'No Customer Found',
];
return response()->json($response, 404);
}
}
/**
* Show the form for creating a new resource.
*
* #return \Illuminate\Http\Response
*/
public function create()
{
//
}
/**
* Store a newly created resource in storage.
*
* #param \Illuminate\Http\Request $request
* #return \Illuminate\Http\Response
*/
public function store(Request $request)
{
//
$this->validate($request, [
'Name' => 'required',
'Contact_Number' => 'required',
'Address' => 'required',
'NoOfCans' => 'required',
'Price' => 'required',
]);
$Name = $request->input('Name');
$Contact_Number = $request->input('Contact_Number');
$Address = $request->input('Address');
$NoOfCans = $request->input('NoOfCans');
$Price = $request->input('Price');
$CustomerDetail = new CustomerDetail([
'Name' => $Name,
'Contact_Number' => $Contact_Number,
'Address' => $Address,
'NoOfCans' => $NoOfCans,
'Price' => $Price
]);
if ($CustomerDetail->save()) {
$response = [
'msg' => 'Customer Created',
'Customer' => $CustomerDetail
];
return response()->json($response, 201);
}
$response = [
'msg' => 'An Error Occured',
];
return response()->json($response, 502);
}
/**
* Display the specified resource.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function show($id)
{
//
$Customer=CustomerDetail::find($id);
if($Customer){
$response = [
'msg' => 'Customer Found',
'Customer' => $Customer
];
return response()->json($response, 201);
}
else {
$response=[
'msg'=>'Customer Not Found',
];
return response()->json($response, 404);
}
}
/**
* Show the form for editing the specified resource.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function edit($id)
{
//
}
/**
* Update the specified resource in storage.
*
* #param \Illuminate\Http\Request $request
* #param int $id
* #return \Illuminate\Http\Response
*/
public function update(Request $request, $id)
{
//
$this->validate($request, [
'Name' => 'required',
'Contact_Number' => 'required',
'Address' => 'required',
'NoOfCans' => 'required',
'Price' => 'required',
]);
$CustomerUpdate = CustomerDetail::find($id);
$CustomerUpdate->Name = $request->input('Name');
$CustomerUpdate->Contact_Number = $request->input('Contact_Number');
$CustomerUpdate->Address = $request->input('Address');
$CustomerUpdate->NoOfCans = $request->input('NoOfCans');
$CustomerUpdate->Price = $request->input('Price');
if ($CustomerUpdate->save()) {
$response = [
'msg' => 'Customer Updated',
'Customer' => $CustomerUpdate
];
return response()->json($response, 201);
}
$response = [
'msg' => 'An Error Occured',
];
return response()->json($response, 502);
}
}
And the data gets inserted when i make a post request for store as
{
"Name":"MRK",
"Contact_Number":"1234567890",
"Address":"newyork",
"NoOfCans":"3",
"Price":"20"
}
with Output
{
"msg": "Customer Created",
"Customer": {
"Name": "MRK",
"Contact_Number": "1234567890",
"Address": "newyork",
"NoOfCans": "3",
"Price": "20",
"updated_at": "2016-11-20 17:17:55",
"created_at": "2016-11-20 17:17:55",
"id": 4
}
}
But when I try to Update the same data with PUT or PATCH request
Input
{
"Name":"MRK",
"Contact_Number":"9876543210",
"Address":"Chennai",
"NoOfCans":"2",
"Price":"20"
}
I get the JSON Response as Updated but I don't see the values got Updated in the database
{
"msg": "Customer Updated",
"Customer": {
"ID": 4,
"created_at": "2016-11-20 17:17:55",
"updated_at": "2016-11-20 17:20:44",
"Name": "MRK",
"Contact_Number": "9876543210",
"Address": "Chennai",
"NoOfCans": "2",
"Price": "20"
}
}
The database contains the values which are originally inserted at first. No updated values are inserted into the database
enter image description here
Update code
public function update(Request $request, $id)
{
//
$this->validate($request, [
'Name' => 'required',
'Contact_Number' => 'required',
'Address' => 'required',
'NoOfCans' => 'required',
'Price' => 'required',
]);
$CustomerUpdate = CustomerDetail::find($id);
$CustomerUpdate->Name = $request->input('Name');
$CustomerUpdate->Contact_Number = $request->input('Contact_Number');
$CustomerUpdate->Address = $request->input('Address');
$CustomerUpdate->NoOfCans = $request->input('NoOfCans');
$CustomerUpdate->Price = $request->input('Price');
if ($CustomerUpdate->save()) {
$response = [
'msg' => 'Customer Updated',
'Customer' => $CustomerUpdate
];
return response()->json($response, 201);
}
$response = [
'msg' => 'An Error Occured',
];
return response()->json($response, 502);
}

Answer 1

The problem is with the model. I have not mentioned the primary key in my model so the database is not updated
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class CustomerDetail extends Model
{
//
public $table = "customer_details";
Protected $primaryKey = "ID";
protected $fillable = [
'Name', 'Contact_Number','Address','NoOfCans','Price'
];
}
