Django syncdb not updating

You can use this option in your local development environment, but since your local development settings module may not have many of your production settings, you will probably want to point the ) from being dumped.If you specify a model name, the output will be restricted to that model, rather than the entire application. This basic fact of life spurs the need for a tool to handle gracefully the problem of altering a database when you can have copies in production, on staging servers, and in developer’s local machines.

But what do you do the first time you get an error?

Here, we will be accustomed to as many error messages as possible while building a small app to store recipes.

Django fosters rapid development, using an easy-to-learn and easy-to-read language like Python will let you not only make the computer understand what you mean, but also the people who may eventually inherit your scripts.

The components of Django are loosely coupled, so you can use another templating language instead of Django’s own, and you can even change the model layer to use Sqlalchemy instead of the built-in Django ORM (Object relational mapper: the layer that translates your models to database language).

South’s migration system really comes into its own when you start getting conflicting migrations - that is, migrations that have been applied in the wrong sequence.

One example is if Anne writes new migrations 0003_foo and 0004_bar, runs the migration up to 0004 to make sure her local copy is up-to-date, and then updates her code from (say) Subversion.

In the meantime, her coworker Bob has written a migration 0003_baz, which gets pulled in. 0003_baz should have been applied before 0004_bar, but it hasn’t been; in this situation, South will helpfully say something like: Running migrations for aeblog: - Current migration: 5 (after 0004_bar) - Target migration: 5 (after 0004_bar) !

These migrations should have been applied already, but aren't: - 0003_baz !

If that’s all set, then simply use the attribute that represents the state the models in your app should be in when the migration is complete.
