Laravel - Controller Separation of Concerns with Relational Data

Good day to All,

I am just curious as to how you peeps are separating the controller workload.

Lets say I have the following controllers:

1. ItemController
2. ItemImageController

So it should be clear that an item may have multiple images.

Now when storing the data for relevant models:

How would you handle the upload / persisting of the Image record? Would you do your insert to db from the ItemController@store method?

If NOT - how do you do this as usually you would have the Item and Image fields on the same view and form?

Cause in my situation I am sitting with the following form:

        {!! Form::open(array('route' => 'items.store', 'method' => 'POST', "files" => true)) !!}
            <div class="row form-group">
                
                <div class="col-md-6">
                    {!! Form::label('name', 'Item:') !!}
                    {!! Form::text('name', "", ["class" => "form-control"]) !!}                     

                    {!! Form::label('description', 'Description:') !!}
                    {!! Form::textarea('description', "", ["class" => "form-control]) !!}
                    

                    {!! Form::label('photos[]', 'Photos:') !!}
                    {!! Form::file('photos[]', ["class" => "form-control", "multiple"]) !!}

                </div>
                </div>

            <div class="row form-group" >
                <div class="col-md-6">
                    {!! Form::submit("Save", ["class" => "btn btn-md btn-primary"]) !!}
                </div>
            </div>
        {!! Form::close() !!}

So you can see the form will be posted to: "items.store" ake ItemController@store. How will I store the photos from that controller? Should the ItemImageController@store method not be responsible for that and how do you reference ItemImageController@store from inside ItemController@store?

I really would like to keep controllers clean and also follow good practices.

Thanks :)
