Use of Repeatable inside Relationship

[lieto-dk]

Hi,

I have an issue while using the Repeatable field inside a Relationship field. When cliciking on the Add item for the Repeatable a new record is shown for the Relationship. My code is as below for the relationship field. Anyone with any ideas what goes wrong ?

$this->crud->addField([
'name' => "categorylocale",
'type' => 'relationship',
'label' => 'Category Locales per Site',
'tab' => 'Locales',
'new_item_label' => 'Add Locale for Category',

],
[
'name' => 'name_locale',
'type' => 'text',
'label' => 'Name (locale)',
'wrapper' => ['class' => 'form-group col-md-4'],
],
[
'name' => 'slug',
'type' => 'text',
'label' => 'Slug',
'wrapper' => ['class' => 'form-group col-md-4'],

Have updated Backpack (pro to 1.5.0) and published assets. Tested in browser where cache was cleared. Same issue.

Hello @lieto-dk

At the present moment it's not possible to use a repeatable inside repeatable. When you set the field type to relationship with subfields, under the hood you are creating a repeatable field. And that would fail when you add a repeatable in the subfields.

Depending on the use-case, sometimes the table field type would be enough for the job.
I have plans to make repeatables work inside other repeatables in future (prob. after v6 launch) but apart from the technical aspect, I think most difficult to achieve is the design/presentation aspect.

I've added a section to the docs to make it more clear for other developers too. Laravel-Backpack/docs#398

Let's see what we can come up after v6 is launched. 🙏

Thanks @lieto-dk

Thanks for the reply.
The table field will not work for this use case.
Will try to solve the issue with a morphMany instead.
