Where and how do I set an environmental variable u

Question

I'm trying to use this env variable to specify the path for my templates and it will probably be easier to do this using git or svn.

Answer 1

The reference material is here. But the operative line for your project path (in case that's what you mean) is:

sys.path.append('/path/to/project')

However, your template path is set within your settings.py file:

TEMPLATE_DIRS = ( '/path/to/templatedir1', '/path/to/templatedir2' )

Answer 2

In you app.wsgi file do:

import os
os.environ['MY_ENV_VARIABLE'] = 'value'
# e.g. os.environ['MPLCONFIGDIR'] = '/path/to/config/dir'
