This is a work in progress, answering questions that do indeed get asked frequently on the Django IRC channel (#django on irc.freenode.net). Feel free to contribute, but try to keep it clear and concise. Please don't editorialize.
How do I learn Python if I'm new to programming?
How do I learn Python if I'm not new to programming?
Are there any books on Python?
Which version should I use, the 0.95.1 release or the Subversion checkout?
The 0.95.1 release is the most well-tested. That said, many people run sites based on a Subversion checkout happily. If you do use a Subversion checkout, note that you don't need to run
setup.py -- just make sure that the checkout is on your Python path.
Should I read the documentation on the djangoproject.com website, or djangobook.com?
Start with the documentation here. This is especially true if you're using 0.95.1, since the version that djangobook.com describes has some significant differences.
'function' object has no attribute 'rindex' mean?
This error is a telltale sign that you're trying to follow djangobook.com with a version of Django that's too old. See previous question.
How do I extend a model? I want to subclass django.contrib.auth.models.User.
You can't do this at the moment, but model subclassing is being worked on. Also, see here. http://www.b-list.org/weblog/2007/02/20/about-model-subclassing
If I change my model, will
manage.py syncdb update my database table?
No, you'll need to manually change your database table. If you use
manage.py sqlall on your app to produce a SQL file before editing your models, you can run it again afterwards and use the difference between the two to see what you need to change in the database.
What should I use for development -- the built-in server, mod_python, FastCGI?
It's generally easiest to use the built-in development server, since it automatically reloads your Python source files when it detects changes. (Some prefer to replicate the production environment as closely as possible, meaning that if their deployed project uses mod_python then their development server does as well.)
What's the difference between
blank=True in models?
null=True means that the database will accept a
NULL value for that field;
blank=True means that Django's validation system won't complain about a missing value. If you use
blank=True but not
null=True you will need to have your code fill in a value before storage in the database -- specifying a default on a field, or putting something in the model's
save method to generate a value are two good ways to handle this, and can be extremely useful when you want to calculate one field's value based on others.
I think Ajax is awesome! How do I do Ajax with Django?
Is there a free CMS available for Django?
At this point there is nothing well-established (like Plone, for instance). In practice, people mean so many different things by "CMS" that it may be hard to get a straight answer. This question is often asked by newcomers; one recommendation is to learn a bit of Django and see just how easy it is to make a site that does what you want. If you're in a big rush, there's always Ellington: http://www.ellingtoncms.com/
What database should I use?
For development, most people find SQLite to be fastest and simplest to run with. (But make sure the database and its directory are writeable by the owner of the web server process!)
You're running the development server, right? Read this: http://www.djangoproject.com/documentation/static_files/
I'm trying to install Django on Windows and something is weird.
Have you looked here? http://code.djangoproject.com/wiki/WindowsInstall
What editor is best for Django?
When will the next release be out? -or- When will X branch be done?
"When it's done" is the short answer. Fixed release dates are rarely set, but searching or browsing the developer list (http://groups.google.com/group/django-developers/) can be informative.
