I'm maintaining a json api with pyramid. And one of the request I
get on occasion is some way to provide help docs on demand for a
given endpoint. Something like.....
/user/login?email=...&password=...
which maps to a UserModel context with view name = "login"
would normally call the view but ideally it would be nice to provide
something like....
/user/login/__help__ or /user/login?__help__
if it could return the docstring from the function, the permission
required, whether the user has the permission or not, and any
paramaters expected on the request that would be a good start.
So a response like
{view:"login",permitted:true, "permission_required":"anonymous",
parameters:["email","password"]}
So it seems I need a way to hook into pyramid at the point that the
context and view are selected, but because the view may be secured i
need a way to look determine whether it's a call to the view or a
call to get documentation about the view.
Since there is no IViewSelected event to subscribe to, my first
thought was to subscribe to the IContextFound event and take a bit
of the code from pyramid.views to go through the view selection but
not call it. This way, I can handle the case where a view
documentation request comes in.
The problem is, that this event occurs in a very delicate place
inside pyramid. I can't raise a new Context and expect the view
selection machinery to pick it up and do what I'm expecting.
So, due to copy/pasting code out of pyramid and seeing solutions
that monkey patch pyramid to get what I want, I'm assuming I'm doing
it wrong. So, I'm asking if there's a pyramid way to provide what I
want. I've got the view paramater stuff figured out, I just would
like to know if there's a pattern I can use to customize what
happens between after the context is found, and after a view is
found but before it is ran.
