-------------------------------------------
After the SpatiaLite library and tools have been installed, it is now possible
to create spatial database for use with GeoDjango. In order to do this, download
the spatial database initialization SQL from the `SpatiaLite Resources`__ page::
to create a spatial database for use with GeoDjango.
For this, a number of spatial metadata tables must be created in the database
before any spatial query is performed against it.
If you are using SpatiaLite 3.0 or newer then use the ``spatialite`` utility to
call the ``InitSpatiaMetaData()`` function whch will take care of that (you can
safely ignore the error messages shown) then you can skip the rest of this
section::
$ spatialite geodjango.db "SELECT InitSpatialMetaData();"
the SPATIAL_REF_SYS table already contains some row(s)
InitSpatiaMetaData ()error:"table spatial_ref_sys already exists"

If you re using a version of Spatialite older than 3.0 then to achieve the same
result you need to download a database initialization file and execute the SQL
queries it contains against your database.
First, get it from the appropiate SpatiaLite Resources page (i.e.
http://www.gaia-gis.it/spatialite-2.3.1/resources.html for 2.3 or
http://www.gaia-gis.it/spatialite-2.4.0/ for 2.4)::
$ wget http://www.gaia-gis.it/spatialite-2.3.1/init_spatialite-2.3.sql.gz
$ gunzip init_spatialite-2.3.sql.gz
(Or, if you are using SpatiaLite 2.4 then do::
$ wget http://www.gaia-gis.it/spatialite-2.4.0/init_spatialite-2.4.sql.gz
$ gunzip init_spatialite-2.4.sql.gz
)
Now, the ``spatialite`` command can be used to initialize a spatial database::
$ spatialite geodjango.db < init_spatialite-2.3.sql
$ spatialite geodjango.db < init_spatialite-2.X.sql
