copied!<p>I guess you have something like this at the top of your file:</p> <pre><code>from django.contrib.comments.admin import CommentAdmin </code></pre> <p>This import executes the registration of the model (at the very bottom of this admin file) <strong>again</strong>.</p> <p>One idea that doesn't look very nice (I actually haven't tried it) could be:</p> <pre><code>from django.contrib.comments.models import Comment from django.contrib import admin from django.contrib.admin.sites import NotRegistered # Try to unregister the Comment model # that was registered via the auto_discover method try: admin.site.unregister(Comment) except NotRegistered: pass # Now we can load the CommentAdmin (which reregisters the admin model) from django.contrib.comments.admin import CommentAdmin # We have to unregister again: try: admin.site.unregister(Comment) except NotRegistered: pass # Now your stuff... </code></pre> <p>I guess this could be done better but it should work. To make this approach work, the application that contains this file has to be after the comments application in <code>INSTALLED_APPS</code>.</p> <p>Now to your class. I think if you write <code>actions = ['ban_user']</code> you actually overwrite all the actions in the parent class. I think it is the easiest way to override the <code>get_actions</code> method:</p> <pre><code>class NewCommentAdmin(CommentAdmin): def get_actions(self, request): actions = super(NewCommentAdmin, self).get_actions(request) # Do some logic here based on request.user if you want # to restrict the new action to certain users actions.append('ban_user') return actions def ban_user(self, request, queryset): pass admin.site.register(Comment, NewCommentAdmin) </code></pre> <p>Hope that helps (or at least gives an idea) :)</p>
