Competences in Noi

I did one change which I realized yesterday

• I added the new table TicketsByCompetence and a detail_layout for Competence (and no list of tickets in the grid).

While working, I realized that we cannot use Votes.project, we do need a separate model Wish. And a bit later I realized that these shared projects are maybe not really what we want. Actually I did not find many tickets for which we need it. But the competences table is a great new feature. So #1563 (the original idea) goes to sleep until we have serious need, and I opened new ticket #1584 and marked it ready.

A side effect:

• I opened #1583 (detail_layout without insert_layout). Until now had the behaviour of using the detail_layout when no insert_layout was defined.

Django’s auto_now_add feature

Another quick release to jane revealed that our usage of lino.modlib.mailbox causes a nice challenge:

$ ./make_snapshot.sh
Started manage.py dump2py snapshot (using lino_sites.jane.settings) --> PID 7090
Writing /snapshot/restore.py...
Traceback (most recent call last):

    full_model_name(model), f.name))
Exception: django_mailbox.Message.processed.auto_now_add is True : values will be lost!
Done manage.py dump2py snapshot (PID 7090)

I “fixed” Lino so that it just logs a warning instead of aborting the dump as a whole. But the problem is not really solved. Django’s auto_now_add feature is what I count into Django’s oddnesses. And I am not alone. It means that the Message.processed field will lose its value on each dump/restore. I guess that this is not acceptable in the long run. We should ask the mailbox project whether they agree to change their code (and how we can use the new development version). This is #1587.

Miscellaneous

One quick push and pull was for an AttributeError 'NoneType' object has no attribute 'project' caused by lino_noi.lib.tickets.ui.

inv bd fails in book

As a preparation of the big release@cpaseupen tonight, I tried to get the test suite and the docs build. Especially #1460 was a tough one:

/lino/utils/xmlgen/__init__.py:docstring of lino.utils.xmlgen:0: WARNING: Inline emphasis start-string without end-string.

It seems that this comes only when the package does from functools import partial. I fixed our problem with this by not importing functools.partial() into the global namespace of any module.
