Learning from yesterday

I solved #107, at least theoretically. To be tested on the field by #108.

A ticket for Mahmoud

Created new #109 and assigned it to Mahmoud.


Created new #110. This is waiting for confirmation from Chatelet.

Final sprint in Eupen

Recorded and fixed a subtle new ticket #111.

  • First of all there was a translation problem: “Ausgestellte Bescheinigungen” –> “Ausgestellte Bestätigungen”
  • The problem was in lino.modlib.excerpts.models.post_init_excerpt() when setting the default language of a new excerpt. I had been thinking that the recipient overrides the owner, but as it turns out it is the opposite: the owner overrides the recipient. This rule is important when they specify both a recipient and a language on the Confirmation.

setup() got an unexpected keyword argument ‘known_values’

Created new #112 and fixed it. Here is the exception:

The problem was in lino.core.kernel.Kernel.run_callback() who created the callback request always as an instance of ActorRequest. But most requests are instances of TableRequest instances. We must take care to create the right class.

Left for a future occasion: Why did lino_welfare.projects.std.tests.test_beid not find this bug? Write a test case which would have detected the problem.

Applets using “resources from the remote locations”

When I go to a Lino site with DavLink and The EIDReader applet, I currently always need to manually confirm two exceptions:

The application [DavLink|EIDReader] from uses resources from the following remote locations:

Are you sure you want to run this application?

Tutorials and the test suite

I noted that The Lino Polls tutorial is part of the test suite, but it is not a demo project (see demo_projects). This means that running the Lino test suite does currently not create a persitent cached demo database and a media/cache of that project. To get that, we would need to move the Python code from /docs to /lino (i.e. to somewhere under lino.projects). That’s needed when running the test suite on Travis. This move would require substantial changes in the text. But it would have another advantage: we would be able to write more than one tested document about the same demo project.
