HasMany relationship old input - laravel

Question

I have a model Category. Category has many Localization. When I store Category, I have these inputs:
{{ Form::text('title[en]', Input::old('title')) }}
{{ Form::text('title[ru]', Input::old('title')) }}
Which I store like this in my controler:
// Gett all inputs
$inputs = Input::all();
// Create resource
$item = Category::create([]);
// Create localization
foreach(Input::get('title') as $locale => $title)
{
$locale = new Localization(['locale' => $locale, 'title' => $title]);
$locale = $item->localization()->save($locale);
}
That works great but what is the best practise for updating such relationships? Currently I'm trying that with Form::model binding.
#foreach($locales as $key => $locale)
{{ Form::text('title['.$locale.']', $model->translate($locale)->title, ['class' => 'form-control']) }}
#endforeach
I have no idea how Input::old could work in this situation, so now I'm using $model->translate($locale)->title to get the correct value. Basically the updating/validation part doesn't really work. What you could suggest to change to validate such relationship and update it?

Answer 1

Today I found a working solution storing/updating relationships with validation. I hope it's the best/simplest way to do that. I created a new array with inputs for validation and changed in the view errors accordingly.
This is my update controller.
public function update($id)
{
// Find resource
$item = Category::find($id);
foreach(Input::get('title') as $locale => $title)
{
$v['title_'.$locale] = $title;
}
// Attempt validation
if($item->validate($v))
{
foreach(Input::get('title') as $locale => $title)
{
$localization = $item->translate($locale);
$localization->title = $title;
$localization->save();
}
return Redirect::action('AdminCategoryController#edit', [$item->id]);
}
else
{
// Failure, get errors
$errors = $item->errors();
return Redirect::back()
->withInput()
->with('errors', $errors);
}
}
And this is the update view;
{{ Form::model($model, ['action' => ['AdminCategoryController#update', $model->id], 'method' => 'PUT']) }}
#foreach($locales as $key => $locale)
<div id="{{ $locale }}">
<div class="form-group">
{{ Form::label('title['.$locale.']', _('admin.title_'.$locale)) }}
{{ Form::text('title['.$locale.']', $model->translate($locale)->title, ['class' => 'form-control']) }}
#if($errors->has('title_'.$locale))
<div class="help-block alert alert-danger">{{ $errors->first('title_'.$locale) }}</div>
#endif
</div>
</div>
#endforeach
{{ Form::close() }}
This way you can easily CRUD, validate all types of relationships (input arrays) in Laravel.
