================================== Integrating with a legacy database ================================== While Django is best suited for developing new applications, it's quite possible to integrate it into legacy databases. Django includes a couple of utilities to automate as much of this process as possible. This document assumes you know the Django basics, as covered in the `official tutorial`_. .. _official tutorial: ../tutorial01/ Give Django your database parameters ==================================== You'll need to tell Django what your database connection parameters are, and what the name of the database is. Do that by editing these settings in your `settings file`_: * `DATABASE_NAME`_ * `DATABASE_ENGINE`_ * `DATABASE_USER`_ * `DATABASE_PASSWORD`_ * `DATABASE_HOST`_ * `DATABASE_PORT`_ .. _settings file: ../settings/ .. _DATABASE_NAME: ../settings/#database-name .. _DATABASE_ENGINE: ../settings/#database-engine .. _DATABASE_USER: ../settings/#database-user .. _DATABASE_PASSWORD: ../settings/#database-password .. _DATABASE_HOST: ../settings/#database-host .. _DATABASE_PORT: ../settings/#database-port Auto-generate the models ======================== Django comes with a utility that can create models by introspecting an existing database. You can view the output by running this command:: python manage.py inspectdb Save this as a file by using standard Unix output redirection:: python manage.py inspectdb > models.py This feature is meant as a shortcut, not as definitive model generation. See the `django-admin.py documentation`_ for more information. Once you've cleaned up your models, name the file ``models.py`` and put it in the Python package that holds your app. Then add the app to your ``INSTALLED_APPS`` setting. .. _django-admin.py documentation: ../django-admin/ Install the core Django tables ============================== Next, run the ``manage.py syncdb`` command to install any extra needed database records such as admin permissions and content types:: python manage.py syncdb See whether it worked ===================== That's it. Try accessing your data via the Django database API, and try editing objects via Django's admin site.
