source: main/waeup.sirp/trunk/src/waeup/sirp/students/browser.py @ 7229

Last change on this file since 7229 was 7229, checked in by Henrik Bettermann, 13 years ago

Implement contact form to send messages to students.

helpers.py: Let get_user_account look for the right IAuthenticatorPlugin (works well with students and users but not with applicants).
applicants/authentication.py: Add getAccount method which returns None at the moment (to let the tests pass).
