## Teaching takes time¶

Yesterday Mahmoud and I worked on #38, it was very interesting for us and good for Lino… but now I had another two hours of work for getting the test suite to pass again under Django 1.6 :-)

• choicelist_choices used by the choicelist field of properties.PropType.
• The ChoiceList.class_init we introduced yesterday forgot to call super.

## Release in Eupen¶

Instead of increasing the version number and writing a migrator, I manually removed the following line in the restore.py file generated by that version of Lino:

# execfile("dupable_partners_word.py")


Uncommenting a line of code is less work that writing a migrator.

I also invoked this manually:

## New test case for duplicate clients¶

Our three concrete cases of duplicate clients in Eupen were still not detected due to a minor bug in find_similar_instances of DupableClient. Fixed the bug and wrote a test case test_dupe_clients to verify it.

## Session with Mahmoud¶

Some notes during our next session.

I noticed that the term “management command” in the Django documentation has been replaced by “django-admin command”. Seems that I must update the Lino documentation accordingly.

We discovered another black hole in the documentation: /dev/site_config.

Mahmoud asked “Why do I need to pass this globals() when instantiating a SITE?”, and it took me more than a minute to find the answer in the documentation. And this answer then was not deep enough to be useful. The missing piece for him was that “global”, in Python means “per module” and not “per process”.

The big chain of imports of many subclasses of the lino.core.site.Site class can seem confusing. But it gives us a hierarchy of places where we can define and override attributes and methods of an application. For example:

Or:
