If that's the case you may want to override response_change() instead.
This method is quite complex and determines which message to display
depending on what action the user just triggered (save, save and
continue, save and add new, etc).

My custom message (WARNING) is now displayed, but also the predefined
Mezzanine message (SUCCESS), both are displayed, as shown in the
following image

Hello everyone,
I need send a message to admin from the /save/ /method/ in a
/model/, something like that:
|
classMyModel(Displayable,Ownable,RichText):
# some field
defsave(self,*args,**kwargs):
# do something
# set the message to be displayed
super(MyModel,self).save(*args,**kwargs)
|
Then, in the admin, the message should be displayed when the form
is sent (save).
I have done a test after having read documentation, questions on
stackoverflow.com <http://stackoverflow.com>, etc. The test
doesn't generate errors during the execution but I don't get the
result I want, the default Mezzanine message is still displayed,
my custom message isn't displayed.
The code of my test would look like that:
|
fromdjango.db importmodels
fromdjango.utils.translation importugettext_lazy as_
frommezzanine.core.models importDisplayable,Ownable,RichText
fromdjango.contrib importmessages
fromdjango.test importRequestFactory
fromdjango.contrib.messages.storage.fallback importFallbackStorage
defcreate_request(url):
factory =RequestFactory()
request =factory.get(url)
setattr(request,'session','session')
messages =FallbackStorage(request)
setattr(request,'_messages',messages)
returnrequest
classMyModel(Displayable,Ownable,RichText):
# some field
defsave(self,*args,**kwargs):
# do something
url ="/admin/path_to/the_instance/%s/change/"%self.id
request =create_request(url)
messages.error(request,_("My custom message."))
|
As I said earlier, this does not generate errors, but the message
is not displayed.
Please, how can I do it?
