Bug report

My Setup

I have a Posts model and a Posts Type model. The posts model has a “post_type_id” field to store the relation.

On the Posts model, I declare the hasOne relation like so:

public function type()
{
    return $this->hasOne('App\Models\PostType', 'id', 'post_type_id');
}

The Backpack Problem

In my Post CRUD Controller, I have the following under setupCreateOperation()

CRUD::addField([
            'label' => "Type",
            'type' => 'select',
            'name' => 'post_type_id',        // the db column for the foreign key
            'entity' => 'type',              // the relationship name in your Model
            'attribute' => 'name',           // foreign key attribute that is shown to user
]);  

When editing or creating a post, the form looks correct and I can see all the Post Types in the select box. Great!

The problem is that when I save the form I get an error:

Add [post_type_id] to fillable property to allow mass assignment on [App\Models\PostType].

The error makes no sense because “post_type_id” exists in the “Post” model (not PostType model) and it is fillable on the Posts model.

What am I do wrong?

My apologies, the problem was actually quite obvious. I had the wrong field value in the belongsTo relationship. It was defined as id when it should have been post_type_id.

Hi @lucidlive

My suggestion is to have a look at Backpack/NewsCRUD package. You need to view it like:

• Article is your Posts. (Has a BelongsTo relation with Category)
• Category is your Post Type.

Check models, database schema and controllers as an example.

I am with @tabacitu on this one, I still think this is something related with a bad implementation rather than a Backpack bug.

If you find i am wrong and this a bug please re-open.

Wish you the best, Pedro
