A pluggable session implementation for Pyramid

Project Description


Want to be able to change out session backends using a simple configuration change, want to store your session data in a new location but re-implementing ISession from Pyramid looks too daunting, fear not, pyramid_pluggable_session makes this really simple.

Is this a pyramid_beaker replacement?

Yes. Although I’ve already been told that unless I implement ALL existing beaker backends that I am not doing it right, so I am hereby doing it wrong ;-).

Pull requests

Want to add a new backend? Perfect. Want to write some tests? Documentation? The whole nine yards? Please!

  1. Clone this repo, create a new topic branch, and hack hack hack.
  2. Push your topic branch to Github
  3. Create a new pull request
  4. I will review it, and if all is well pull it into this source tree!


  • Add better protection against session fixation:
    • Upon failure to deserialize/unpack/expiration of session a new session id is generated.
    • Upon calling invalidate() a new session is generated with a new session id
  • Add more clean-up using the new clear() functionality. When a session fails to deserialize, we remove it from the backends, if a session fails to unpack we remove it from the backends, and if it has expired we also remove it from the backends.
  • Update the included backends memory/file/chain to add the new clear() function required by IPlugSession.
  • Add clear() to IPlugSession interface to allow the session to explicitly have the backend plugs remove the session data associated with a certain session id.
  • On _save_session we set the cookie to response that is provided to us by the callback, and not request.response which may not be the users response.


New features:

  • A file based session storage now exists.
  • A chain can now be constructed for session storage


  • A new ISession compliant Pyramid session provider appears.
  • A single backend exists, it is based on local Pyramid memory.
