I can hide all the options in the model base, but is not necessary, on the relation i can't do that i think that exist a simple form (not with css) to remove or hide it
Thanks
I agree with Ivan Camilito Ramirez Verdes's solution :
class MyModelAdmin(admin.ModelAdmin):
list_display = (
'my_field',
)
def get_form(self, request, obj=None, **kwargs):
form = super().get_form(request, obj, **kwargs)
form.base_fields['my_field'].widget.can_change_related = False
form.base_fields['my_field'].widget.can_add_related = False
return form
