Advancing with Lino Voga¶
Continuous courses are a new concept in Lino Voga. It is another way of managing enrolments to a course. While a classical course has a fixed and previously known series of calendar events, a continuous course is running all the time. Participants pay a fee which gives them permission to assist in a number of events, and then they come and go.
I removed the rule that the
enrolments_until of a course is
set to its
Because there are continuous courses
The Roger variant of Lino Voga has referrable courses. Last year they introduced a “reference number” for every single course. TODO: what will happen next year with these numbers? I suggest to change the ref of the 2016 courses with “2016” so that the known references can be reused for the corresponding 2017 course.
TODO: where should the new Course.ref appear?
lino.modlib.about.models.About window now shows the
languages of that site.
ValueError: dictionary update sequence element #0 has length NN; 2 is required¶
This comes because wkhtmltopdf needs a manual patch in
def render_to_temporary_file(template, context, mode='w+b', bufsize=-1, suffix='.html', prefix='tmp', dir=None, delete=True): # deactivated by Luc Saffre 20160206 # make sure the context is a context object # if not isinstance(context, (Context, RequestContext)): # context = Context(context) content = smart_text(template.render(context)) content = make_absolute_paths(content)
And then I still had the following error:
CalledProcessError: Command ‘[‘wkhtmltopdf’, ‘–encoding’, u’utf8’, ‘–quiet’, ‘/tmp/wkhtmltopdfQW_4es.html’, ‘-‘]’ returned non-zero exit status -6
This was because the wkhtmltopdf system package (not python) is 0.12.1 instead of 0.9.9.
It’s a known bug. Here is how to demonstrate it:
$ wkhtmltopdf --encoding utf8 --quiet test.html - QXcbConnection: Could not connect to display Aborted
Solution was to
Lino goes Wikipedia¶
Oh cool, Hamza started a Wikipedia article about Lino:
