Validating pyramid requests

I have a pyramid application with many defined routes. I want to do a few different server-side checks whenever a user makes a request and possibly redirect the request if certain criteria are met.

I realize I could add these checks to each of the view functions, but I'd like to avoid having to update and add boilerplate to dozens of view functions.

Is there a way in pyramid to perform some checks for all requests, before they're sent onto the view functions?

Solution

  • I believe you are looking for a NewRequest event: 

    from pyramid.events import NewRequest
from pyramid.events import subscriber

@subscriber(NewRequest)
def new_request_subscriber(event):
    validate_request(event.request)
