Description

Fields added to a ModelAdmin.exclude are not excluded when generating a "readonly" view as per the new functionality

Class MyModel(models.Model):
    field_to_show = models.TextField(default='foo')
    field_to_exclude = models.TextField(default='should be hidden')
@admin.register(MyModel)
Class MyModelAdmin(admin.ModelAdmin):
    exclude = ('field_to_exclude',)

    def has_change_permission(self, request, obj=None):
        return False

In the above example the field_to_exclude will be rendered on the "readonly" change view

Hi Ben,

I can't reproduce this in my test project:

I have an admin + a view-only user for that admin. All fields are shown as read-only. I add one field to exclude. It is no-longer shown.

That's what I'm expecting.

Can you perhaps provide a test project with your exact setup, as there's obviously some difference. (Or even better add a test case to the test suite showing the bad behaviour if that's possible.)

Happy to re-open if we can reproduce.

Thanks.

Turns out this occurred due to the field being in both exclude and readonly_fields. In other situations (a field specified in two places) this throws an error.

Hi Ben,

Thanks for the follow-up.

It might be possible to add a system check for that situation, if it really doesn't make sense (which at first glance it doesn't). Is your thought that you would want an error here? If so do you have capacity to add a system check do you think?
