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.
