Custom view wrappers¶
If you want to extend functionality beyond the basic logic behind a Nomadblog
view, you can call, from your wrapper view function, one of the _ctxt
functions defined in views.py
directly with your context. Passing a
RequestContext
to the function will update it with the expected values
needed for rendering the response. If you do not pass any RequestContext
object, a new one is created and returned.
Basically the idea behind having the business logic separated from template context population is that you can have the basic functionality of the action performed in the blog (get a list of posts, show the contents of a post) isolated and DRY, and add or modify business logic to your wrapper view.
I wrote a post trying to explain better this approach. Also, the four
Nomadblog actions represented by their four view functions — list posts
,
show post
, list categories
, show post by category
— in the
views.py
code are actually the best examples to implement your own wrapper.
