在Laravel / Eloquent中比较两个模型

Question

I have the table item_list and the table users

I have the pivot table allowed_items that contains item_id from the item_list and user_id from the user table.

I have some checkbox list that should be checked when the item and the user are in the pivot table, and be left unchecked if it does not.

I am currently doing this:

$items = item_list::all();
$allowed_items = allowed_items->where("user_id",$user_id")->get();
foreach ($allowed_item as $allow)
{
$allow_array[$allow->item_id] = true;
}

Then I return the view and check if the item exists like this:

@foreach($items as $item)
<input type="checkbox" value="{{$item->id}} 
{{array_key_exists($item->id,$allow_array") ? "checked":" "}}>
@endforeach

This works, but it feels unprofessional. Any way to do this in the controller?

Answer 1

If you want a cleaner code you can make into the Item controller a new method call eg isAllowed which will return a boolean function.

Item controller

public function isAllowed(){
// check if exists and return yes/no
}

Template

@foreach($items as $item)
   <input type="checkbox" value="{{$item->id}} 
   {{$item->isAllowed() ? "checked":" "}}>
@endforeach

If you can give us more details I'll edit my answer to properly answer your question.
