Laravel不遵守相关模型更新的批量分配$可填充规则

Question

I have business and profile models in my Laravel app. A business hasOne profile. I've created a patch method form using the form builder to update my business and profile tables.

Blade

{!! Form::model($business, ['route' => ['business.edit.post', $business], 'method' => 'PATCH']) !!}
                @include('forms.business.edit')
{!! Form::close() !!}

BusinessController

public function update(Request $request, $id)
{
    $business = Business::findOrFail($id);

    $business->update($request->all());
    $business->profile()->update($request->all());        

    return back()->withMessage('updated');
}

Now using a patch method will include a hidden field called _method along with the built in _token field for csrf protection. I am getting an error when it updates the profile model stating:

SQLSTATE[42S22]: Column not found: 1054 Unknown column '_method' in 'field list' (SQL: update `business_profiles` set `_method` = PATCH, `_token` = Zyxtxa88uUQKhaRQNY8k7qPu2N0i6o20dY4sUABk, `city` = Belfast where `business_profiles`.`business_id` = 107 and `business_profiles`.`business_id` is not null)

It appears to me its trying to update those hidden fields when it shouldn't. When commenting out the _ profile->update line the save works fine. It looks like updating related Models does not adhere to the mass assignment rules built into Laravel. Could someone advise how to fix this?

Answer 1

You can either add $fillable to your model or use $request->only([]) .

EDIT

Looks like the problem is you are updating through the relationship. The simple fix, as you figured it out and as comments suggest, is to change $business->profile()->update($request->all()); to $business->profile->update($request->all()); .

Answer 2

I wanted to make use of $fillable on my Models and not have to manually state which columns are to be populated.

I altered my update method as follows:

$business = Business::findOrFail($id);
$profile = $business->profile;

$business->update($request->all);
$profile->update($request->all);

I'm sure theres a smarter way to do this, but this will do for now :-)
