I'm new to Laravel and breaking my head trying to work with relationships.
I have 2 tables: members groups
And a pivot table: member_group
A member can belong to many groups, a group can have many members.
When I edit a member, I create checkboxes for the groups.
I need to mark the ones that the member already has as 'checked'
My edit method:
public function edit($id)
{
$cities = City::orderBy('city_name')->pluck('city_name', 'city_id');
$member = Member::findOrFail($id);
$groups = Group::all();
return view('members.edit', compact('member', 'cities', 'groups'));
}
In my edit.blade:
@foreach($groups as $group)
<?php $exists = $member->groups()->where('groups.group_id', $member->group_id); ?>
@if($exists)
<input type="checkbox" name="groups[]" value="{{ $group->group_id }}" checked> {{ $group->group_name }}
@else
<input type="checkbox" name="groups[]" value="{{ $group->group_id }}"> {{ $group->group_name }}
@endif
....
All the checkboxes are checked, although the member does not belong to all the groups.
Looking at this post: Stackoverflow post I tried almost everything they offer there, only got errors. The only one that works is this one: $exists = $member->groups->contains($group->group_id);
Don't know about wastefulness or not, it's the only one that works.
I think, in your blade $exists = $member->groups()->where('groups.group_id', $member->group_id);
you should use group.group_id
instead of groups.group_id
and also use first()
method.
$exists = $member->groups()->where('group.group_id', $member->group_id)->first();
Can you try this ?
$member = Member::findOrFail($id)->with(['groups'=>function($query){
$query->selectRaw('groups.group_id');
}])->first();
And in blade:
$exists = $member->groups()->whereIn('groups.group_id', $member->groups)->first();
