Django cheap-pages

Methods to use when you just want to use the Django dispatcher and there will be no extra business logic in your pages.

In some cases flatpages is too flat, and store templates in DB is too much hassle

    >>> url(^name/$,
    ...    direct_to_template,
    ...    {'template': 'name.html'},
    ...    name='name')

    can be expressed as:
    >>> page('name')

    urlpatterns = patterns('', ...)
    urlpatterns += build('Regexp', ['page1', 'page2', ...])
