How do I alter the models I already have?

16. How do I alter the models I already have?

If you need to alter the models you've already made, there are two options:

1. If don't mind losing the data you already have in the database for that model you can run python reset modelName . This is of course done after you have made the changes you wanted to the model.

2. If you don't want to lose the data, you have to alter the tables manually with SQL. What you do is to go into your database server shell by running python dbshell. From there you can run normal ALTER TABLE sql commands.
