完整性約束違規：1048列'company_id'不能爲空laravel5.3

Question

我嘗試將（Table company）（Company id - > primary key）設置爲（Table branch）（company_id）中的外鍵。

控制器：

public function savebranchinfo(Request $request){ 
     $validator = Validator::make($request->all(),[ 
      'name' => 'required|min:5', 
      'email' =>'required|unique:branch', 
      'address' =>'required', 
      'contact' =>'required|min:11', 
      'open_hours' =>'required', 
     ]); 
     if($validator->passes()){ 
      $branch = new Branch(); 
      $branch->company_id = $request->company_id; 
      $branch->name = $request->name; 
      $branch->email = $request->email; 
      $branch->address = $request->address; 
      $branch->contact = $request->contact; 
      $branch->open_hours = $request->open_hours; 
      if($branch->save()){ 
       $request->session()->flash('message','Successfully save!!'); 
       return redirect('/add/branch'); 
      } 
     }else{ 
       return redirect('/add/branch')->withErrors($validator)->withInput(); 
     } 
    } 
} 

遷移：

public function up() 
{ 
    Schema::create('branch', function (Blueprint $table) { 
     $table->increments('id'); 
     $table->integer('company_id')->unsigned(); 
     $table->foreign('company_id')->references('id')->on('company'); 
     $table->String('name'); 
     $table->String('email'); 
     $table->String('address'); 
     $table->String('contact'); 
     $table->String('open_hours'); 
     $table->timestamps(); 
    }); 
} 

檢視：

<input type="hidden" value="company_id{{$company->id}}"> 

錯誤：

SQLSTATE [23000]：完整性約束違規：1048列「COMPANY_ID '不能b E無效（SQL：插入branch（company_id，name，email，address，contact，open_hours，updated_at，created_at）值（，馬哈茂德子，mahmoodson@gmail.com，比拉爾甘吉，04237152734，8 am-8pm，2017-02- 25 12點06分35秒，2017年2月25日12時06分35秒））

在我看來，你在表單忘了輸入名稱：

<input type="hidden" name="company_id" value="{{$company->id}}">
