django_db_prefix

Project goal

Allow specification of a global, per-app or per-model database table name prefix.

Reason for the project

1. Some (external) projects automatically use a database prefix for interaction with a database. This is particularly common in implementations of the Active Record pattern.

2. It is possible to define an explicit database table name in the Meta class on a model; however, this is not as easily accomplished when dealing with a third-party application. By providing a high-level interface for adding prefixes there is a simple, consistent way to achieve this goal other than forking the code or ad-hoc monkey patching.

Installation

1. Install using pip:

   pip install git+https://github.com/maxvyaznikov/django-db-prefix.git

2. Add django_db_prefix at the top of your INSTALLED_APPS list. It is recommended that django_db_prefix is the first listed application, but it is essential that it be loaded before the initialization of any model you expect to be modified.

Configuration

Three configuration options are allowed: global, per-app or per-model. In all cases, the specified prefix will be prepended exactly as provided -- no delimiter will be added.

In all cases, behavior is controlled by the DB_PREFIX setting.

Global Prefix

To add a common prefix to all models simply set DB_PREFIX to the string that you want to be prepended.

DB_PREFIX = "foo_"

For example, for the model bar_app.models.Baz the default table would be: bar_app_baz

By setting DB_PREFIX to foo_, the table would be foo_bar_app_baz.
