Backpack for Laravel (select2_multiple)

Question

I need to select multiple users and display the names as developers. But I get this error.

Exception Property [name] does not exist on this collection instance. (View: D:\Laravel\BoomTech\bug-tracker\resources\views\project_issues.blade.php)

Code that should show the name/s of users:

{{ $issue->developer->name }}

Issues table:

public function up()
{
    Schema::create('issues', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->foreignId('project_id');
        $table->foreignId('submitted_by_id');
        $table->foreignId('developer_id');
        $table->string('title', 255);
        $table->string('comment', 255)->nullable();
        $table->mediumText('description');
        $table->text('status');
        $table->text('type');
        $table->timestamp('created_at')->nullable();
        $table->timestamp('updated_at')->nullable();
        $table->timestamp('deleted_at')->nullable();
    });
}

Issue User (pivot table):

Schema::create('issue_user', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->foreignId('user_id');
        $table->foreignId('issue_id')->nullable();
        $table->timestamp('created_at')->nullable();
        $table->timestamp('updated_at')->nullable();
    });

Issue Model:

public function developer()
{
    return $this->belongsToMany('App\Models\User', 'issue_user', 'issue_id', 'user_id');
}

IssueCRUDController:

CRUD::addField([    // Select2Multiple = n-n relationship (with pivot table)
        'label' => "Developer",
        'type' => 'select2_multiple',
        'name' => 'developer', // the method that defines the relationship in your Model

        // optional
        'entity' => 'developer', // the method that defines the relationship in your Model
        'model' => "App\Models\User", // foreign key model
        'attribute' => 'name', // foreign key attribute that is shown to user
       'pivot' => false, // on create&update, do you need to add/delete pivot table entries?
    ]);

Answer 1

This is many to many relationships so you need to do like this:

public function developers()
{
    return $this->belongsToMany('App\Models\User', 'issue_user', 'issue_id', 'user_id');
}


@foreach($issue->developers() as $developer)
{{ $developer->name }}
@endforeach
