当我更新数据或删除或创建数据时不起作用。该代码没有给出任何类型的错误，因此对我来说似乎不错。当我尝试更新它时，更新后的数据出现在url中，但没有出现在数据库中。删除功能也一样。数据库是mysql。下面是我的控制器代码
<?php
namespace App\Http\Controllers;
use App\Company;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
class CompaniesController extends Controller
{
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index()
{
//
$comapanies = Company::all();
return view('companies.index',['companies'=>$comapanies]);
}
/**
* Show the form for creating a new resource.
*
* @return \Illuminate\Http\Response
*/
public function create()
{
return view('companies.create');
}
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request)
{
if(Auth::check()){
$company = Company::create([
'name'=>$request->input('name'),
'description'=>$request->input('description'),
'user_id'=>Auth::user()->id
//OR 'user_id'=>$request->user()->id above 5.5 versions of laravel
]);
if($company){
return redirect()->route('companies.show', ['company'=>$company->id])
->with('success', 'Company Created Successfully');
}
}
return back()->withInput()->with('errors', 'Error while creating company');
}
/**
* Display the specified resource.
*
* @param \App\Company $company
* @return \Illuminate\Http\Response
*/
public function show(Company $company)
{
$company = Company::where('id', $company->id)->first();
// $company = Company::find($company->id);
return view('companies.show', ['company'=>$company]);
}
/**
* Show the form for editing the specified resource.
*
* @param \App\Company $company
* @return \Illuminate\Http\Response
*/
public function edit(Company $company)
{
$company = Company::find($company->id);
return view('companies.edit', ['company'=>$company]);
}
/**
* Update the specified resource in storage.
*
* @param \Illuminate\Http\Request $request
* @param \App\Company $company
* @return \Illuminate\Http\Response
*/
public function update(Request $request, Company $company)
{
$companyupdate = Company::where('id', $company->id)->update([
'name'=>$request->input('name'),
'description'=>$request->input('description')
]);
if($companyupdate){
return redirect()->route('companies.show',['company'=>$company->id])
->with('success','Company Updated Successfully');
}
return back()->withInput()->with('errors', 'Updation failed');
}
/**
* Remove the specified resource from storage.
*
* @param \App\Company $company
* @return \Illuminate\Http\Response
*/
public function destroy(Company $company)
{
$findcompany = Company::find($company->id);
if($findcompany->delete()){
return redirect()->route('companies.index')
->with('success', 'Company Deleted Successfully');
}
return back()->withInput()->with('errors', 'Company could not be deleted');
}
}
这是“编辑”视图代码
@extends('layouts.app')
@section('content')
<div class="col-md-9 col-lg-9 col-sm-9 pull-left">
<!-- Jumbotron -->
<div class="row col-lg-12 col-md-12 col-sm-12" style="background-color:white; margin:10px;">
<form mehtod="post" action="{{ route('companies.update', [$company->id]) }}">
{{ csrf_field() }}
<input type="hidden" name="_method" value="put">
<div class="form-group">

<input placeholder="Enter Name"

这是我的公司模式
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Company extends Model
{
Protected $fillable = [
'name',
'description',
'user_id',
];
public function users(){
return $this->belongsTo('App\User');
}
public function projects(){
return $this->hasmany('App\Project');
}
}
答案 0 :(得分：0)
在模型中添加表名
在这里，我使用表名“ companies”，可以将其替换为表名
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Company extends Model
{
protected $table = 'companies';
Protected $fillable = [
'name',
'description',
'user_id',
];
public function users(){
return $this->belongsTo('App\User');
}
public function projects(){
return $this->hasmany('App\Project');
}
}
在路由文件（web.php）中：
Route::resource('companies', 'CompaniesController');
在用于存储和更新功能的控制器更改代码中：
public function store(Request $request){
$post = $request->all();
$user = Auth::User();
if($user){
$company = Company::create([
'name'=> $post['name'],
'description'=> $post['description'],
'user_id'=> $user->id
]);
if($company){
return redirect('/companies/'. $company->id)->with('success', 'Company Created Successfully');
} else {
return redirect('/companies/create')->with('error_message', 'Something went wrong!');
}
}
}
public function update(Request $request, $id){
$post = $request->all();
$company = Company::find($id);
$company->update($post);
return redirect('/companies/'. $company->id)->with('success', 'Company Updated Successfully');
}
