[Django]-Django: Remove message before they are displayed

I had to use 2 of the solutions proposed above toghether as no one alone was enought:

storage = messages.get_messages(request)
for _ in storage: 
    pass

if len(storage._loaded_messages) == 1: 
    del storage._loaded_messages[0]

As far as the accepted solution I can loop over the messages several time
and I see that the messages don’t seem to be “consumed”

I like this simpler approach for clearing out the underlying iterator, since I actually wanted to add a new message in the place of a standard Django message.

list(messages.get_messages(request))

If your logout view always redirects to a “logout page”, then you can just change your logout template to hide your messages.

e.g., in template:

{% block extra-header %}
<style type="text/css">
    #message-id { display: none; }
</style>
{% endblock %}

It feels a little ‘hacky’ but I think it’s certainly less hacky than your #2.

For me in Django 1.5 and session message storage accepted method dit not the trick.

I needed to use:

storage = messages.get_messages(request)
for _ in storage:
    pass

To get rid of messages from storage.

One way of doing the same thing in Django Admin (tested with Django==1.11.6) is to override response_post_*.

def response_post_save_change(self, request, obj):
    storage = messages.get_messages(request)
    storage._loaded_messages = []

    return super().response_post_save_change(request, obj)

And if you want to keep only your custom messages (e.g. added in save_model or any other overridden method) remove the last queued message (which is the one Django ads by default).

def response_post_save_change(self, request, obj):
    storage = messages.get_messages(request)

    if len(storage._queued_messages) > 1:
        del storage._queued_messages[-1]

    return super().response_post_save_change(request, obj)
