Cannot print accounting report in cosi-ee demo

lino.modlib.users.UserPlan.create_user_plan() didn’t like it when it found more than one instances of a plan for a given user. In lino_book.projects.cosi3 it said MultipleObjectsReturned: get() returned more than one Report -- it returned 2! Now it simply deletes them all in that case. This should fix #3232.

But it doesn’t yet. Because the reports cannot be deleted. It says:

AjaxExceptionResponse ProtectedError: ("Cannot delete some instances of model
'Report' because they are referenced through a protected foreign key:
'AccountEntry.report'", <QuerySet [AccountEntry #1 ('AccountEntry object
(1)'), AccountEntry #2 ('AccountEntry object (2)'), AccountEntry #3
('AccountEntry object (3)'), AccountEntry #4 ('AccountEntry object (4)'),
AccountEntry #5 ('AccountEntry object (5)'), AccountEntry #6 ('AccountEntry
object (6)'), AccountEntry #7 ('AccountEntry object (7)'), AccountEntry #8
('AccountEntry object (8)'), AccountEntry #9 ('AccountEntry object (9)'),
AccountEntry #10 ('AccountEntry object (10)'), AccountEntry #11 ('AccountEntry
object (11)'), AccountEntry #12 ('AccountEntry object (12)'), AccountEntry #13
('AccountEntry object (13)'), AccountEntry #14 ('AccountEntry object (14)'),
AccountEntry #15 ('AccountEntry object (15)'), AccountEntry #16 ('AccountEntry
object (16)'), AccountEntry #17 ('AccountEntry object (17)'), AccountEntry #18
('AccountEntry object (18)'), AccountEntry #19 ('AccountEntry object (19)'),
AccountEntry #20 ('AccountEntry object (20)'), '...(remaining elements
truncated)...']>)

Indeed the allow_cascaded_delete of the report items weren’t set correctly! For PartnerEntry it was ['partner'], for ItemEntry it was ['item'] and for AccountEntry it was ['account']. This was plain bullshit. When you inadvertently try to delete a partner who is mentioned in an accounting report, you want Lino to refuse your action (not to remove the entry from the report).

TODO: So from now on it might happen that deleting a partner or an account is being refused because some old accounting report exists. This might disturb because Lino doesn’t currently tidy up these reports after some time. A site manager can however go to Explorer ‣ Accounting ‣ Accounting reports and delete them manually.

There is maybe yet another bug in lino_xl.lib.sheets : #3233. Less urgent.

Another screencast about Lino

I published my second screencast about Lino on YouTube: Lino Così, das kleine Buchhaltungsprogramm. This second one is a replacement for the first one which I published yesterday. You can also see at least one demo effect. Yes, sorry, it’s in German. After all that’s the easiest language in the world for me…
