提问by Shebs72
I have been pulling my hair out with this error for a few hours now but cannot understand why it is doing it. I have done this before on Laravel but it just does not seem to want to work.
几个小时以来，我一直因这个错误而拉我的头发，但不明白为什么会这样。我之前在 Laravel 上做过这个，但它似乎不想工作。
This is the method I am trying to get to work:
这是我试图开始工作的方法：
public function store($name, CreateProfileRequest $request)
{
$user = User::whereName($name)->first();
$house = new House();
$house->first_line_address = $request->get('first_line_address');
$house->city = $request->get('city');
$house->postcode = $request->get('postcode');
$user->house()->save($house);
return redirect('/');
}
This is the form I am trying to get the data from:
这是我试图从中获取数据的表单：
{!! Form::model($user->house, ['route' => 'profile.store']) !!}
<div class ="form-group">
{!! Form::label('first_line_address', 'First line of address:') !!}
{!! Form::text('first_line_address', null, ['class' => 'form-control'])!!}
</div>
<div class ="form-group">
{!! Form::label('city', 'Town/City:') !!}
{!! Form::text('city', null, ['class' => 'form-control'])!!}
</div>
<div class ="form-group">
{!! Form::label('postcode', 'Postcode:') !!}
{!! Form::text('postcode', null, ['class' => 'form-control'])!!}
</div>
<div class ="form-group">
{!! Form::submit('Update Profile', ['class' => 'btn btn-primary']) !!}
</div>
{!! Form::close() !!}
</div>

This is my route:
这是我的路线：
$router->resource('profile', 'ProfileController');
| GET|HEAD | profile | profile.index | App\Http\Controllers\ProfileController@index | |
| 得到|头| 简介 | profile.index | App\Http\Controllers\ProfileController@index | |
| | GET|HEAD | profile/create | profile.create | App\Http\Controllers\ProfileController@create | |
| | 得到|头| 个人资料/创建 | profile.create | App\Http\Controllers\ProfileController@create | |
| | POST | profile | profile.store | App\Http\Controllers\ProfileController@store | |
| | 发布 | 简介 | profile.store | App\Http\Controllers\ProfileController@store | |
| | GET|HEAD | profile/{profile} | profile.show | App\Http\Controllers\ProfileController@show | |
| | 得到|头| 个人资料/{个人资料} | profile.show | App\Http\Controllers\ProfileController@show | |
| | GET|HEAD | profile/{profile}/edit | profile.edit | App\Http\Controllers\ProfileController@edit | |
| | 得到|头| 个人资料/{个人资料}/编辑 | profile.edit | App\Http\Controllers\ProfileController@edit | |
| | PUT | profile/{profile} | profile.update | App\Http\Controllers\ProfileController@update | |
| | 放 | 个人资料/{个人资料} | profile.update | App\Http\Controllers\ProfileController@update | |

| | DELETE | profile/{profile} | profile.destroy | App\Http\Controllers\ProfileController@destroy | |
| | 删除 | 个人资料/{个人资料} | profile.destroy | App\Http\Controllers\ProfileController@destroy | |
If anyone thinks of how to get rid of this ridiculous error I will be forever grateful :)
如果有人想到如何摆脱这个荒谬的错误，我将永远感激:)

If you want an instance of Requestto be available to your controller method, it must be the first argument, followed by other arguments passed via URI. Reverse the methods.
如果您希望Request控制器方法可以使用的实例，则它必须是第一个参数，然后是通过 URI 传递的其他参数。颠倒方法。

The store()method of a resource controller/route doesn't take any route parameters. That means Laravel has nothing to pass as $nameargument. I suppose you're passing the name in the request data itself. If that's the case you can access it with $request->input('name').
store()资源控制器/路由的方法不采用任何路由参数。这意味着 Laravel 没有什么可以作为$name参数传递的。我想您是在请求数据本身中传递名称。如果是这种情况，您可以使用$request->input('name').
Anyways you should remove $namefrom the method signature:
无论如何，您应该$name从方法签名中删除：
public function store(CreateProfileRequest $request)
