Sqlite doesn't support app names with underscores in them for column opperations

[caleb_brown@…]

We are using an sqlite3 database.

We ran code like this in a migration:

db.rename_column('app_name_modelname', 'column', 'new_column')

This error was returned:

KeyError: "The model 'name_modelname' from the app 'app' is not available in this migration."

The problem appears to be with the DatabaseOperations::_alter_sqlite_table() method in south.db.sqlite3

In particular, the following line treats only the characters before the first underscore as the app name:

model_name = table_name.replace('_', '.', 1)
