Problem using "relationship" in Lists and Views

[infiniteroles]

Hello, I am trying to display a column in the list where the wallet addresses associated with a user appear.

In the User model, I have:

public function wallets()

{
    return $this->hasMany(Wallet::class);
}

nd in the wallets table, I can have multiple wallets assigned to the same user_id. I want to display a column in the user list where those wallets appear.

I’m trying with this, but I only see empty content:

        CRUD::addColumn([
            'name' => 'wallets',
            'type' => 'relationship',
            'label' => 'Wallets',
            'entity' => 'wallets',
            'attribute' => 'address',
            'model' => "App\Models\Wallet",
        ]);

I think I’m misunderstanding something about the relationships, in fact, the relations_count isn’t working well for me either.

Could it be that I’m missing something?

Thanks

@infiniteroles does your wallets table have an address column ?

If it's a simple text column, just do CRUD::addColumn('wallets.address').

Let me know if that helps 🙏

I get this error:

Call to undefined method App\Models\Wallet::identifiableAttribute()

and I have this in my user model:

    public function wallets()
    {
        return $this->hasMany(Wallet::class);
    }

and this in my crud file:

CRUD::column('wallets');

I also tested creating a new function with a different name, but I had the same problem.

Thanks so much

From that error I think you forgot to add the CrudTrait in your model. Can you confirm ?

[infiniteroles]

It was missing in Wallet Model. Now I donñ´t have any error, but wallet colum is empty. :-(

Did you define the column just as CRUD::column('wallets')->attribute('address') and let Backpack guess the other stuff?

Can you go to vendor/backpack/crud/src/resources/views/crud/columns/select_multiple.blade.php and add a dd($column['value']) before the @endphp tag ?

Cheers
