Description:

When using fieldsForDetail, any pivot fields in any BelongsToMany Relation will be ignored.
If the same relation exists in the fields method, it will be used instead of anything in fieldsForDetail

Detailed steps to reproduce the issue on a fresh Nova installation:

add BelongsToMany relation with ->fields() inside public function fieldsForDetail without add it to public function fields

You still need to add BelongsToMany to fields(), or fieldsForIndex() method

[MuathIbnHassan]

unless I don't want to update or create the field, the problem is that ->fields()'s callback (public $fieldsCallback) registered in fieldsForDetail will never be called on the detail page

[crynobone]

The detail page are for the parent resource, when you want to fetch the content of BelongsToMany it is an Index request.

[MuathIbnHassan]

yes it will be rendered in the index, but the customization for the index is inside the callback

if I want to customize the parent field (BelongsToMany)'s data I cannot, right?

also if I use two relations to the same model the pivot data will be used in all of them, I want to specify them because I may have multiple pivots tables between two same models, but with this, I will not be able to specify pivot for them all, am I right?

I will try to do a proof of concept for the last point in a new repo, but this is happening right now in my project
