When trying to use Mako with the Pyramid framework, by going into the development.ini file, and adding the line 

mako.directories = TestProject:templates

in:

[app:TestProject]

and then creating a simple html file called template.mako in the templates subdirectory I get an:

ImportError: No module named TestProject

But I fail to understand why this is happening after the above steps. Why are those steps generating an importError?

More detials of the error:

As summary:

Edit the file development.ini and add in the section [app:MyProject]:

mako.directories = myproject:templates

Now we can open the file /MyProject/myproject/__init__.py and add a line like:

config.add_route('foo', '/foo', view='myproject.views.foo', view_renderer='foo.mako')

This will render the template located in: /MyProject/myproject/templates/foo.mako

Note: MyProject and myproject are the name of YOUR project. Respect the case.

Remember to do the same configuration in production.ini file!

Edit:I see in the 1.3a1 version of pyramid (2011-12-09) Changelog in the Features section:

A mako.directories setting is no longer required to use Mako templates Rationale: Mako template renderers can be specified using an absolute asset spec. An entire application can be written with such asset specs, requiring no ordered lookup path.

    It appears that for pyramid 1.3, the `mako.directories = myproject:templates` setting goes under `[app:main]`, not `[app:MyProject]` – Hollister Apr 08 '12 at 01:51

It happens because the mako.templates specifiction is in the format of package:directory. Therefore you must have a package called, in your case, "TestProject".

You may have a package for your project, but it's apparently not called "TestProject".
