Snippet List
Facebook Authentication Backend
Authentication through Facebook's Graph API. See [http://developers.facebook.com/docs/authentication/](http://developers.facebook.com/docs/authentication/) [http://developers.facebook.com/docs/authentication/permissions](http://developers.facebook.com/docs/authentication/permissions) [http://developers.facebook.com/docs/api](http://developers.facebook.com/docs/api) [http://github.com/facebook/python-sdk/blob/master/examples/oauth/facebookoauth.py](http://github.com/facebook/python-sdk/blob/master/examples/oauth/facebookoauth.py) Define the facebook tokens in settings.py and replace <app_name> with the name of your app. You will probably want to modify the scope on the authorize link in the template, see the authentication permissions link. This updates the user model every time the user logs in but I think that it is okay so the data is always correct. I have tested this but not rigorously. If there is a hole and everyone gets admin rights to your site don't say I didn't warn you :). Comments are appreciated. 16 June 2010 Added missing imports. Cleaned up the template. Shouts out to @obeattie and @whalesalad

Model dependency graph using graphviz (script)
Instructions: Set your environment variables, install graphviz, and run. Finds all models in your installed apps and makes a handsome graph of your their dependencies based on foreignkey relationships. Django models have green outlines, yours have purple. The edge styling could be changed based on edge type.

dynamic model graph
This view assumes you have downloaded [modelviz.py](http://django-command-extensions.googlecode.com/svn/trunk/extensions/management/modelviz.py) and placed it in a python module called utils within my_project. You also must have graphviz installed and a subprocess-capable python. From there you can feed it a URL query list of the options you want to pass to generate_dot, and it will dynamically draw png or svg images of your model relationships right in the browser. All it wants is a nice form template for graphically selecting models. Most of this code and the main idea thereof was shamelessly plagiarized from [someone else](http://gundy.org/). Examples: `http://localhost:8000/model_graph/?image_type=svg&app_labels=my_app&include_models=Polls&include_models=Choices` `http://localhost:8000/model_graph/?image_type=png&all_applications&disable_fields&group_models`

Using the {% widthratio %} template tag with CSS to create a bar graph
The {% widthratio %} template tag is under appreciated! Here, it's combined with CSS to create a bar graphic for the results of an election (this example comes from [this page](http://flickr.com/photos/postneo/405239750/in/photostream/), but has been modified slightly for simplicity's sake). The widthratio tag can be used to create all sorts of graphs and charts, as well as things like tag clouds. Here, we pass it the number of votes for a candidate, the total number of votes in the election, and the integer 190, which is the width, in pixels, of a "full" bar on the bar graph. In other words, 100% = 190 pixels. It works great!
