Many bug fixes and usability enhancements

2015-10-30 QUENLIG-2.4.0.tar.gz
It should be fully compatible with old questionnaries.
Many new things, look the documentation to have more information:

  • QUENLIG now displays page with UTF-8 character encoding.
  • The storage of students information is now done as Python tuples.
  • The course documentation can be automaticaly generated from the questions with the 'courses' and 'before' attributes. The HTML tag 'KEY' is used to create an index of keywords.
  • The file 'QUENLIG/Questions/.../HTML/questions.js' is integrated in the web page for the questionnary.
  • It is possible to restrict the usage to a single IP address, for example a web proxy.
  • When using {{{}}} in a question, there are new functionnalities:
    • {{{ shuffle}}} The toggles and radio order is randomised
    • {{{toggle}}}
    • {{{!radio}}} there are mixable.
  • The 'competences' plugin allows with the 'Grade' test to define competences and display the question list by competence. There are nice graphics to see the student progression. The student can choose the "best" question in a competence or in the full question list. It is the question needing the more work.
  • It is possible to Grade for a tuple of teachers (competence) in one time.
  • It is possible to have multiple versions for the same question, so the student can retry the same question with other values. The 'Choice' test make it easy to do so. This functionnality has not been tested outside 'competence' plugin, in this case, 'allowed_to_change_answer' plugin is needed.
  • The required question list can now have attributes:
    # The question must only be seen, not answered
    # In the answered questions bloc: display the 'before' attribute
    # In the answered questions bloc: do not display the question
