# 20121221¶

Continued on the “CMS project” (docs/tickets/66). I now use Jinja2 instead of lino.utils.memo.

Somebody who tried the public demo sites found two bugs:

• Calling http://demo2.lino-framework.org/admin/api/countries/Country/BE?fmt=plain caused a TypeError “get_window_layout() takes exactly 2 arguments (1 given)”, lino.ui.extjs3.views, line 832. This was a simple typo bug.
• Calling http://demo2.lino-framework.org/admin/api/cal/MyPresences?fmt=pdf caused a PodError “I cannot write result file …/homeworkschool/media/cache/appypdf/cal.MyPresences.pdf [Errno 2] No such file or directory…”. The corresponding code forgot to call lino.core.modeltools.makedirs_if_missing(). By the way I solved a theoretic problem: if two simultaneous requests called a [pdf] version of the same actor, they would generate the same file. Now the filename includes the remote IP address.

After having fixed these bugs I decided to make a quick upgrade of the demo sites. Which was of course a risky thing after all the changes to lino.modlib.pages. And indeed it caused the demo sites to be offline for a few hours because there were still plenty of issues in the new CMS functions.
