Removing a relation in a GridField

[baba-papa]

The GridFieldAddExistingAutocompleter helps making relation between objects. I would expect the scaffolded the GridField to offer a button to remove relations but there is only a button to delete the whole object. Is there a solution for this issue?

Further I suggest that objects may only be deleted in their own ModelAdmin for security reasons.

To quote the PHPDoc for the class ;)

Often used alongside {@link GridFieldRemoveButton} for detaching existing records from a relationship.

Incidentally, that's the wrong class name, should be GridFieldDeleteAction - which I've just fixed.

That might be useful in your context, but others will want to provide full edit/delete

capabilities in different "views", one of which can be a ModelAdmin.

There's no concept of "an object's own ModelAdmin" in core,

you can have the same object editable through GridFields in other places,

even through multiple ModelAdmins. I would suggest you simply don't add the 

GridFieldDeleteAction component to views where you want to avoid deletion,

and leave global permission management to canDelete().
