django tests using postgis

[funkmyster]

When running our newly developed test suite for geolocation, I kept receiving:

createlang -d test_<projectDB> -U <username> plpgsql
Traceback (most recent call last):
  File "./manage.py", line 11, in <module>
    execute_manager(settings)

    raise Exception("Error executing 'plpgsql' command: %s\n" % output)
Exception: Error executing 'plpgsql' command: 

apparently if 'plpgsql' is pre-installed on the newly generated instance:

createlang -d test_<projectDB> -U <username> plpgsql

...raises an exception with the value 2, thus breaking the test suite. Note my stack was built from source.

Fixed ticket formatting.

We added the POSTGIS_TEMPLATE (​docs) setting for this exact reason -- set it with the name of your ​spatial database template that already has the procedural language created along with the PostGIS extension.

[Vinay Sajip]

I get the same error when trying to create the postgis_template database using the 'create_template_postgis_debian.sh', because plpgsql is apparently already present. Although in this case an error code of 2 is returned from createlang, it's not really an error, so the script should continue to add functions etc. to the template, but it bails before then.

This occurred on Ubuntu Oneiric 64-bit, PostgreSQL 9.1. So I cannot create a valid postgis_template database.

[Aymeric Augustin]

This ticket describes a problem that happens when you run the test suite. If I understand correctly, your problem happens earlier, when your create the postgis_template database, so it's a different one.

Could you create a new ticket, if possible with more detail? Attaching the log of your terminal session would be very useful, we could try to understand the cause without setting up an Ubuntu.

Thanks!
