Best practice for pylons app global tmpl_context settings?

I'm writing a pylons application, and I'm w开发者_开发技巧ondering if there is a best practice for where to set some application specific values of the template context object (tmpl_context)?

Currently, I've added a __before__() method to the BaseController and am setting up the tmpl_context object with values there but am wondering if there is another place.

I think the BaseController is a good place to put that, either in __call__() or in __before__().

a __before__ method is a right place to do it.
