## Inviting others to vote¶

Lino can now automatically create “vote invitations” (i.e. votes having a new state “invited”). I added two other new vote states “pro” and “con”. And we have a new table “My vote invitations” which basically asks the user to choose one of four options:

• Cancelled : not interested. You declare that you don’t want to be bothered with this ticket.
• Watching : You are interested, you are neutral and did not yet declare your opinion. You want to be notified when something happens in this ticket.
• Pro : optimistically watching. You declare that you want this ticket to get done. You support this ticket.
• Con : skeptically watching. You declare that you want this ticket to get refused.

The pro and con states are not yet used, but I plan to also make the number of pro, con and watching votes visible in the WishesByMilestone view. So you can do polls in Noi by formulating your questions as tickets, creating an activity and adding them as tickets, and then adding enrolments to your activity. The participants will automatically be invited to vote. Note that you must click the Save button of the activity for Lino to create vote invitations.

• I added a new method Commentable.on_commented. And Votable now invites the comment’s author to vote on this votable.
• Similar system for Workable.on_worked.
• I changed the label of the ticket state “Cancelled” to “Refused”.
• The label of a lino.core.workflows.ChangeStateAction is now being inherited from its target_state. Don’t ask me why I didn’t see this earlier.

## Vocabulary and translations¶

I did a series of renames, without (yet) changing any model names.

Especially in the lino_xl.lib.cal plugin I started to tidy up with the obsolete term “calendar event”. This word is still being used in many places for what should actually be called a “calendar entry”. For example:

MyEvents -> MyEntries
AllEvents  -> AllEntries
PublicEvents -> PublicEntries
EventsByRoom -> EntriesByRoom
Events -> Entries
EventsByDay -> EntriesByDay

EventStates -> CalendarEntryStates

MoveEventNext -> MoveEntryNext

ConflictingEvents -> ConflictingEntries

EventChecker -> EntryChecker


I also changed some translatable messages:

Calendar Event Types -> Calendar entry types
Event label -> Entry label

Event Policy -> Recurrency policy
Recurrent event rule -> Recurring event


And then our lino_xl.lib.courses plugin. The name “courses” is really wrong because already Lino Voga uses the Course model also for “travels” and “hikes”. They use the word “activities” (Aktivitäten) as the general term. In CPAS de Châtelet they use almost the same thing and call it “workshops” (ateliers). Lino Noi uses it to organize sprints and meetings. Meanwhile I think that the best general term is “Events” (Veranstaltungen, Évènements, Üritused). I am now trying to evolve step by step towards my final goal which is to have “events” which generate “calendar entries”. All in all it is still a big chaos, but only for the developer.

How to disable all fields except some:

class Message(dd.Model):

_disabled_fields = set('body sender subject ...'.split())

def disabled_fields(self, ar):
# fields = super(Message, self).disabled_fields(ar)
# fields |= self._disabled_fields
return self._disabled_fields


Today I discovered a cool thing: I can override the label of a remote field using update_field. sed for Session.ticket__id.
