Hi Eduardo,
I have tried as you suggested, my new test would be something like this:
from django.contrib import messages
from django.utils.translation import ugettext_lazy as _
from mezzanine.core.admin import DisplayableAdmin, OwnableAdmin
class MyModelAdmin(DisplayableAdmin, OwnableAdmin):
# fieldsets, list_display, etc.
def save_model(self, request, obj, form, change):
# do something
return DisplayableAdmin.message_user(request, _("My custome
message."), messages.ERROR)
but now I get the following error:
add_message() argument must be an HttpRequest object, not '__proxy__'.
to see what contains the request object, I have used *raise
Exception(request)* and got
<WSGIRequest: POST '/admin/.../'>
Please, what could I do now?
