So I have a django database I'm working on and I decided I wanted to do the development in sqlite3 instead of mysql. I decided to do this because it makes it easier, for example, to have someone else work on HTML/CSS if I can just give them a directory, tell them to run a bash script and go to http://localhost:8000, rather than them having to do all that AND setup a mysql server. Sure, that can also be done with a script, but with sqlite things are just a hell of a lot easier in some ways.
I decided I wanted to take the data out of my mysql database and load it into a sqlite db. Not so simple, you can't just take an SQL dump from mysql and import it into sqlite3. I started Googling around for "mysql to sqlite" and didn't really get anywhere. I then realized that Django can already talk to sqlite and mysql transparently without me having to know any SQL. So I thought about writing my own python modules to do this, but it turns out someone has already done it.
The django-extensions project has a manage.py command called "dumpscript" that "Generates a Python script that will repopulate the database using objects. The advantage of this approach is that it is easy to understand, and more flexible than directly populating the database, or using XML." This was exactly what I wanted.
