我將表單輸入從角度傳遞到laravel視圖api。但數據不能保存在數據庫中。我收到以下錯誤消息在控制檯：我無法將數據從角度保存到後端laravel數據庫

I also get laravel errors:
<span class="exception_title"><abbr title="Illuminate\Database\QueryException">QueryException</abbr> in <a title="C:\xampp\htdocs\dukamart\vendor\laravel\framework\src\Illuminate\Database\Connection.php line 651" ondblclick="var f=this.innerHTML;this.innerHTML=this.title;this.title=f;">Connection.php line 651</a>:</span>

我檢查我的laravel控制器似乎是罰款。我從彈出窗體發佈數據。
employeeController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Employee;
class Employees extends Controller
{
//
public function index($id = null) {
if ($id == null) {
return Employee::orderBy('id', 'asc')->get();
} else {
return $this->show($id);
}
}
public function store(Request $request) {
$employee = new Employee;
$employee->name = $request->input('name');
$employee->email = $request->input('email');
$employee->contact_number = $request->input('contact_number');
$employee->position = $request->input('position');
$employee->save();
return 'Employee record successfully created with id ' . $employee->id;
}
//我的角度控制器
app.controller('employeesController', function($scope, $http, API_URL) {
//retrieve employees listing from API
$http.get(API_URL + "employees")
.success(function(response) {
$scope.employees = response;
});
//show modal form
$scope.toggle = function(modalstate, id) {
$scope.modalstate = modalstate;
switch (modalstate) {
case 'add':
$scope.form_title = "Add New Employee";
break;
case 'edit':
$scope.form_title = "Employee Detail";
$scope.id = id;
$http.get(API_URL + 'employees/' + id)
.success(function(response) {
console.log(response);
$scope.employee = response;
});
break;
default:
break;
}
console.log(id);
$('#myModal').modal('show');
}
//save new record/update existing record
$scope.save = function(modalstate, id) {
var url = API_URL + "employees";
//append Employee id to the URL if the form is in edit mode
if (modalstate === 'edit'){
url += "/" + id;
}
$http({
method: 'POST',
url: url,
data: $.param($scope.employee),
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).success(function(response) {
console.log(response);
location.reload();
}).error(function(response) {
console.log(response);
alert('This is embarassing. An error has occured. Please check the log for details');
});
}
//delete record
$scope.confirmDelete = function(id) {
var isConfirmDelete = confirm('Are you sure you want this record?');
if (isConfirmDelete) {
$http({
method: 'DELETE',
url: API_URL + 'employees/' + id
}).
success(function(data) {
console.log(data);
location.reload();
}).
error(function(data) {
console.log(data);
alert('Unable to delete');
});
} else {
return false;
}
}
});
當我點擊保存數據，我收到一條錯誤消息，我在employeeController有設置。 js控制器
$http({
method: 'POST',
url: url,
data: $.param($scope.hotel),
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).success(function(response) {
console.log(response);
location.reload();
}).error(function(response) {
console.log(response);
alert('This is embarassing. An error has occured. Please check the log for details');
});
}
這是我app.js
var app = angular.module(employees, [])
.constant('API_URL', 'http://localhost/myapp/public/api/');
我routes.php文件
Route::get('/api/v1/employees/{id?}', '[email protected]');
Route::post('/api/v1/employees', '[email protected]');
Route::post('/api/v1/employees/{id}', '[email protected]');
Route::post('/api/v1/employees/update/{id}',['as'=>'update','uses'=> '[email protected]']);
Route::delete('/api/v1/employees/{id}', '[email protected]');
什麼可能是這個原因嗎？請幫忙。我試圖解決這個問題3天沒有成功。

嘗試使用郵遞員發佈的數據。它會工作或不檢查 –
我收到類似的內部錯誤異常郵寄請求。某處應該有錯。請問我需要一些幫助。 – wafutech
從上面的錯誤它就像你正在存儲數據庫中的錯誤值不遵循數據庫約束 –
