[Feature] Attributes in pivot tables

See original GitHub issue

Bug report

What I did

Trying to create Attach/Detach between two entities connected with M:N relation (pivot table has additional attributes).

I’ve tried couple of different field types (select2_multiple, select_multiple), i even tried to create repeatable field.

Having attributes in pivot tables is like really common (don’t recall project when i didn’t have this)…

What I expected to happen

To be able to specify pivot attributes for each entity i select in select2_multiple, or to have a way to add some custom button with modal where you can attach relation with some additional attrbutes.

What happened

When i was using select_multiple or select2_multiple, additional fields were not showing and application was throwing exceptions (as expected).

When i was trying to use repeatable, data sent to server was in json format, and syncPivot method wasn’t well coded to handle this.

What I’ve already tried to fix it

I’ve just tried different field types.

Hello guys.

Indeed this is something we have discussed and probably we will attempt to provide a solution for this.

I have corretly labeled it, and will have a discussion with @tabacitu about this.

Repeatable https://backpackforlaravel.com/docs/4.1/crud-fields#repeatable might work in this scenario, because you can intercept the request in controller and do whatever you want with it.

Maybe what is missing here is to set the max items a repeatable field can have, so you can set it to only one, am i right ? @Dzale ?
