Determine if current admin form is view-only in __init__

Hi @ciarancourtney, I can't find an easy way to determine this. Maybe, you could try the _has_change_only_permission method. I don't know exactly your case but you could have something like this:

def get_form(self, request, obj=None, **kwargs):
    form = super().get_form(request, obj, **kwargs)
    if self._has_change_only_permission(request, obj):
        return <the_form_that_you_want>

    return form

Hope, this helps you.

Does _has_change_only_permission() return False if user has view and change? If so I think I'd use has_change_permission(), as its typical to layer permission in order of privilege i.e. a view-only user has view perm, a change user has view and change, a full user has view, change, add delete and so on

The _has_change_only_permission runs underneath the super has_change_permission. So, if the user has change permission it will return True otherwise it will return False. In general if you want to determine that the view is view-only you need to have something like this:

if not self._has_change_only_permission(request, obj) and self.has_view_permission(request, obj)
