(Django) Override the change_view in the admin - magicrebirth

Thu, 26 Jan 2012 04:35:50 UTC

Adding another button with name "addnextid" would trigger our custom action, that redirects the user to the changeform screen for the next available item (by ID). Then you can override admin/submit_line.html. Copy the version in contrib.admin.templates into your project. Mine is myproject/templates/admin/submit_line.html, but you could use /myproject/myapp/templates/admin/submit_line.html. Next, edit the copy and add the code for showing the 'Save and edit next item (by ID)' link, which is caught via the "_addnextid" name. p.s. The submit_line.html template is called in change_form.html via the {% submit_row %} tag.

(Django) Clean up expired django.contrib.session\'s in a huge MySQL InnoDB table - magicrebirth

Fri, 30 Dec 2011 23:12:12 UTC

While django provides the django_admin.py cleanup script, if sessions get out of control sometimes you have to go lower level to get everything cleaned up. If the problem gets out of hand and you hit the resource limits of the machine, it is very difficult to get anything done in the database. Attached is SQL code which was used to cleanup 27GB of expired session data in 3h. Run it like this to make sure it runs to completion: `nohup mysql --user=username --password=password --host=hostname database < delete_expired_sessions.sql` nohup causes the script to run detached from a terminal, so if your session gets disconnected it will keep running. p.s. An alternative approach is to launch this command from the shell: DELETE FROM django_session WHERE expire_date < NOW(); or DELETE FROM django_session WHERE expire_date < "2011-12-10 00:00:00";

(Django) Django: adding new admin_tags - magicrebirth

Tue, 22 Dec 2009 15:06:14 UTC

First: create a file under djangoapp/templatetags where you define your tags [e.g.: myadmin_tags.py]: Second: create the html snippets that get loaded in those tags [e.g., personfactoid_info.html]: Third: in mytemplates/admin/ modify change_form.html (if you don't have it just copy it from the django-admin app). You must add a placeholder for the new templatetags (probably you want to add it at the bottom of the page): FOurth: create a new change_form.html in the same directory as above, but under your model template [e.g., mytemplates/admin/myapp/mymodel/change_form.html] so to override the behaviour just for that. The 'object_id' variable is passed by the admin template by default:
