(Django) Override the change_view in the admin

Thu, 26 Jan 2012 04:35:50 GMT

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

Fri, 30 Dec 2011 23:12:12 GMT

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";

(Bash) How to make git use TextMate as the default commit editor « Developmentality

Wed, 12 Oct 2011 06:28:41 GMT

Now when you do a git commit without specifying a commit message, TextMate will pop-up and allow you to enter a commit message in it. When you save the file and close the window, the commit will go through as normal. (If you have another text editor you prefer instead, just change the “mate -w” line to the preferred one) For those curious what the -w argument is about, it tells the shell to wait for the mate process to terminate (the file to be saved and closed).

(Python) Colorizing Python Source Using the Built-in Tokenizer

Tue, 19 Jul 2011 18:01:26 GMT

You need to convert Python source code into HTML markup, rendering comments, keywords, operators, and numeric and string literals in different colors. tokenize.generate_tokens does most of the work. We just need to loop over all tokens it finds, to output them with appropriate colorization:

[from the author's website] I wrote this to better understand the relationship between RGB colors. Running it will generate a fairly large HTML file with all sorts of color transitions on it so you can see what is happening as colors are tweaked in different ways.
