Bug report

What I did

I've created a CrudController and the UpdateOperation with a relationship field from a 1 <> n relation.

 CRUD::field([
            'name'          => 'language_id',
            'type'          => 'relationship',
            'entity'        => 'language', // the method that defines the relationship in your Model
            'label'         => __('backpack.language'),
            'hint'          => __('backpack.create_group_language'),
        ]);

I've already checked all my relations, and they are working properly

What I expected to happen

On the update form / screen I was expecting to have the good ID selected in the relationship field.

If the field is : relationship, the first value of the select is selected, otherwise the good value is displayed

What happened

It is not working with the relationship field, but working with the select field. The field / value that is supposed to be selected is not the good one.

What I've already tried to fix it

Switching from relationship field to the select field.

        CRUD::field([
            'name'          => 'language_id',
            'type'          => 'select',
            'entity'        => 'language', // the method that defines the relationship in your Model
            'label'         => __('backpack.language'),
            'hint'          => __('backpack.create_group_language'),
        ]);

Is it a bug in the latest version of Backpack?

After I run composer update backpack/crud the bug is still there.

Backpack, Laravel, PHP, DB version

When I run php artisan backpack:version the output is:

Hey @Astriel what kind of relationship is that ? BelongsTo ?

Can you try just with the relation name as the field name to check if it does any difference ?

 CRUD::field('language')->label(__('backpack.language')->hint(__('backpack.create_group_language'));

Any chance you have a resources/views/vendor/backpack/pro/fields/relationship.blade.php custom in your app ?

I was about to ask you if you could reproduce it in our demo, and I noticed that in our demo the BelongsTo relationship was not properly working. I thought you were right, but in the end it was a mistake in our end.

We had two fields using the same relationship, so the value of one was overwriting the other.

I've fixed it in https://github.com/Laravel-Backpack/demo/pull/581 and belongsTo relations seems to be working just fine, so I will add that you could check:

that you have not two fields for the same relationship.
that you have the language_id in your $fillable array in the model.

Let me know if that helps.

Cheers
