LaraveL : How to get data from many to many relationship - php

Question

I have 3 tables which are user->id, name,password, roles->id,role, role_user->role_id, user_id
Now if I want to show the associated data in view page means role related to user ..How i do it in view?
means I want to show if the user has role it will be checked otherwise it will be unchecked
Here is my controller :
$users = User::all();
$roles = Role::all();
return view("Permission::assign_role",compact('users','roles'));
View page
<table class="table">
<thead>
<tr>
<th>SL No</th>
<th>Name</th>
<th>Role</th>
</tr>
</thead>
<tbody>
<?php $i = 1; ?>
#foreach($users->roles() as $row)
<tr>
<td>{{$i}}</td>
<td>{{$row->name}}</td>
<td><input type="checkbox" name="role_id" checked> $role->role</td>
</tr>
<?php $i++; ?>
#endforeach
</tbody>
</table>

Answer 1

Eager load the data:
$users = User::with('roles')->get();
return view("Permission::assign_role", compact('users'));
And in the view, you can do something like this if you want to check if user has specific role:
#if ($user->roles->contains($roleId))
If you want to just iterate over user's roles:
#foreach($users->roles as $role)
{{ $role->name }}

This how I am using for my applications :
User Model :
public function roles() {
return $this->belongsToMany(Role::class);
}
Role Model :
public function user() {
return $this->belongsToMany(User::class);
}
In My Controller :
$users = User::all();
In My View
#foreach($users as $user)
#foreach($user->roles() as $role)
{{$role->name}}
#endforeach
#endforeach
