[moin-devel] Extend pages via action as another user

[Jasper Olbrich]

Hi,

I'm trying to create a kind of group mechanism that allows any 
registered user who knows a password to join an existing group in my wiki.

Setup:
* TestGroup page, member list at the bottom of the page
* LetMeIn page with a form field for the password (FormCreate macro)
* custom action deriving from FormSubmit

At first, I tried to edit the current revision of TestGroup on the file 
system level, but there seem to be some caching issues with regard to 
the permissions, or I screwed up the revisions or something else. It 
didn't work reliably.

Then I found the Page and PageEditor classes and did the following:

  real_user = self.request.user
  # 'su'
  u = User(self.request, _getUserIdByKey(self.request, "name", "ol"))
  self.request.user = u
  p = Page(self.request, "TestGroup")
  rev = p.current_rev()
  pe = PageEditor(self.request, "TestGroup")
  pe.saveText(p.get_raw_body() + " * {}\n".format(real_user.name), rev)
  # 'un-su'
  self.request.user = real_user

"ol" is a user that can write to TestGroup.
This code works, but feels kind of wrong. Are there better ways to do 
what I want?
