Testing GeoDjango Apps
|
|
======================
|
|
|
|
.. versionchanged:: 1.2
|
|
|
|
In Django 1.2, the addition of :ref:`spatial-backends`
|
|
simplified the process of testing GeoDjango applications. Specifically, testing
|
|
GeoDjango applications is now the same as :ref:`topics-testing`.
|
|
|
|
Included in this documentation are some additional notes and settings
|
|
for :ref:`testing-postgis` and :ref:`testing-spatialite` users.
|
|
|
|
.. note::
|
|
|
|
Django 1.1 users are still required to use a custom :setting:`TEST_RUNNER`.
|
|
See the :ref:`testing-1.1` section for more details.

|
|
|
|
Settings
|
|
--------
|
|
|
|
.. note::
|
|
|
|
The settings below have sensible defaults, and shouldn't require manual setting.
|
|
|
|
.. setting:: POSTGIS_TEMPLATE
|
|
|
|
``POSTGIS_TEMPLATE``
|
|
^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. versionadded:: 1.1
|
|
|
|
.. versionchanged:: 1.2
|
|
|
|
This setting may be used to customize the name of the PostGIS template
|
|
database to use. In Django versions 1.2 and above, it automatically
|
|
defaults to ``'template_postgis'`` (the same name used in the
|
|
:ref:`installation documentation <spatialdb_template>`).
|
|
|
|
.. note::
|
|
|
|
Django 1.1 users will still have to define the :setting:`POSTGIS_TEMPLATE`
|
|
with a value, for example::
|
|
|
|
POSTGIS_TEMPLATE='template_postgis'
|
|
|
|
.. setting:: POSTGIS_VERSION
|
|
|
|
``POSTGIS_VERSION``
|
|
^^^^^^^^^^^^^^^^^^^
|
|
.. versionadded:: 1.1
|
|
|
|
When GeoDjango's spatial backend initializes on PostGIS, it has to perform
|
|
a SQL query to determine the version. Setting the version manually
|
|
prevents this query to the database::
|
|
|
|
POSTGIS_VERSION=('1.3.6', 1, 3, 6)
|
|
|
|
Obtaining Sufficient Privileges
|
|
-------------------------------
|
|
|
|
Depending on your configuration, this section describes several methods to
|
|
configure a database user with sufficient privileges to run tests for
|
|
GeoDjango applications on PostgreSQL. If your
|
|
:ref:`spatial database template <spatialdb_template>`
|
|
was created like in the instructions, then your testing database user
|
|
only needs to have the ability to create databases. In other configurations,
|
|
you may be required to use a database superuser.
|
|
|
|
Create Database User
|
|
^^^^^^^^^^^^^^^^^^^^
|
|
To make database user with the ability to create databases, use the
|
|
following command::
|
|
|
|
$ createuser --createdb -R -S <user_name>
|
|
|
|
The ``-R -S`` flags indicate that we do not want the user to have the ability
|
|
to create additional users (roles) or to be a superuser, respectively.
|
|
|
|
Alternatively, you may alter an existing user's role from the SQL shell
|
|
(assuming this is done from an existing superuser account)::
|
|
|
|
postgres# ALTER ROLE <user_name> CREATEDB NOSUPERUSER NOCREATEROLE;
|
|
|
|
Create Database Superuser
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
This may be done at the time the user is created, for example::
|
|
|
|
$ createuser --superuser <user_name>
|
|
|
|
Or you may alter the user's role from the SQL shell (assuming this
|
|
is done from an existing superuser account)::
|
|
|
|
postgres# ALTER ROLE <user_name> SUPERUSER;
|
|
|
|
|
|
Create Local PostgreSQL Database
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
1. Initialize database: ``initdb -D /path/to/user/db``
|
|
|
|
2. If there's already a Postgres instance on the machine, it will need
|
|
to use a different TCP port than 5432. Edit ``postgresql.conf`` (in
|
|
``/path/to/user/db``) to change the database port (e.g. ``port = 5433``).
|
|
|
|
3. Start this database ``pg_ctl -D /path/to/user/db start``
|
|
|
|
Windows
|
|
-------
|
|
On Windows platforms the pgAdmin III utility may also be used as
|
|
a simple way to add superuser privileges to your database user.
|
|
|
|
By default, the PostGIS installer on Windows includes a template
|
|
spatial database entitled ``template_postgis``.
|
|
|
|

|
|
|
|
SpatiaLite
|
|
==========
|
|
|
|
.. versionadded:: 1.1
|
|
|
|
You will need to download the `initialization SQL`__ script for SpatiaLite::
|
|
|
|
$ wget http://www.gaia-gis.it/spatialite/init_spatialite-2.3.zip
|
|
$ unzip init_spatialite-2.3.zip
|
|
|
|
If ``init_spatialite-2.3.sql`` is in the same path as your project's ``manage.py``,
|
|
then all you have to do is::
|
|
|
|
$ python manage.py test
|
|
|
|
Settings
|
|
--------
|
|
|
|
.. setting:: SPATIALITE_SQL
|
|
|
|
``SPATIALITE_SQL``
|
|
^^^^^^^^^^^^^^^^^^
|
|
.. versionadded:: 1.1
|
|
|
|
By default, the GeoDjango test runner looks for the SpatiaLite SQL in the
|
|
same directory where it was invoked (by default the same directory where
|
|
``manage.py`` is located). If you want to use a different location, then
|
|
you may add the following to your settings::
|
|
|
|
SPATIALITE_SQL='/path/to/init_spatialite-2.3.sql'
|
|
|
|

Testing GeoDjango Applications in 1.1
|
|
=====================================
|
|
|
|
In Django 1.1, to accommodate the extra steps required to scaffalod a
|
|
spatial database automatically, a test runner customized for GeoDjango
|
|
must be used. To use this runner, configure :setting:`TEST_RUNNER` as follows::
|
|
|
|
TEST_RUNNER='django.contrib.gis.tests.run_tests'
|
|
|
|
.. note::
|
|
|
|
In order to create a spatial database, the :setting:`DATABASE_USER` setting
|
|
(or :setting:`TEST_DATABASE_USER`, if optionally defined on Oracle) requires
|
|
elevated privileges. When using PostGIS or MySQL, the database user
|
|
must have at least the ability to create databases. When testing on Oracle,
|
|
the user should be a superuser.
|
|
|
|
GeoDjango Test Suite
|
|
====================
|
|
|
|
To run GeoDjango's own internal test suite, configure the
|
|
:setting:`TEST_RUNNER` setting as follows::
|
|
|
|
TEST_RUNNER='django.contrib.gis.tests.run_gis_tests'
|
