New workflow for Lino Noi¶
I continued to work on #1285. As I wrote earlier
(Friday, November 25, 2016), my meeting with the new Johannes made us discover that
we need a new model (Vote) in Lino Noi in order to manage the
workflow for Lino Care which is somewhat more complex than in the
team version (lino_noi.projects.team) because there will be
more users.
What’s to do
Now that we have the concept of votes (see Thursday, December 1, 2016), we can have several users wanting to work on a ticket. And only one of them “gets the job”.
We need to review the general workflow. That new workflow is meaningful for the team version as well, so we are going to change both at once.
The Ticket.assigned_to field will no longer be used. Until now this field pointed to the user who is supposed to work on that ticket. This information is now stored in the votes of that ticket.
Migration will probably be a bit tricky, but Lino will manage it.
New states of tickets and votes:
A Vote (Angebot) can have the following states:
watching (Interesse) : I want to get notified about changes in this ticket (but I won’t work on it myself).
candidate (Angebot) : I offer my help and am ready to take responsibility.
assigned (Zugewiesen) : I have been assigned responsibility and am supposed to work on that ticket
ready (bereit) : I think that my job has been done
done (erledigt) : The ticket author has confirmed that my job is done
A ticket (Bitte) can have the following states:
new (Neu) : the reporter is still formulating the ticket. Not all required data has been entered.
opened (Offen) : ticket is waiting for help offers
active (Aktiv) : All helpers have been assigned and can start working. No further help offers wanted.
closed (Abgeschlossen) : all help offers are done
sticky (Permanent) : similar to opened and active, but knowing that the ticket will never close. Stick tickets don’t show in the tasks list.
New views to show in the dashboard:
MyOfferedVotes (Meine Aufgaben) : list my votes which need my attention. help offers
MyRequestedVotes (Meine Anfragen) : list of votes (of other users) on my tickets which need my attention.
Life cycle of a ticket and its votes
Create a ticket. When all required data has been entered, the ticket can move to state “open”.
One or more other users offer their help by creating a Vote instance on that ticket.
Ticket author accepts one or several help offers. Lino notifies these users and they see the ticket in their tasks list.
When the actual work is done, the helper sets its vote to “ready”. Lino notifies the ticket author.
The ticket author rates the vote and puts the ticket to “closed”.
Difference between author and reporter
There will be a new field user, similar to reporter. All existing tickets will be migrated to have both fields with the same value (i.e. user gets the value of reporter for every existing ticket). This is because we must differentiate between the author and the reporter on tickets whose original reporter is not a system user. In that case the reporter will point to the external user while the user is the user who entered the ticket.
Migration notes
for tickets with non-empty assigned_to field : create a vote whose state depends o the ticket state.
dist-upgrade on The Lino framework¶
Today we upgraded The Lino framework from 7 to 8 (wheezy to jessie).
Some errors encountered:
[....] Restarting web server: apache2AH02559: The SSLCertificateChainFile directive (/etc/apache2/sites-enabled/default-ssl.conf:39) is deprecated, SSLCertificateFile should be used instead
Errors were encountered while processing:
libjson0:amd64
E: Sub-process /usr/bin/dpkg returned an error code (1)
This one is still open:
$ python -m datetime
/usr/local/pythonenv/demo/bin/python: No module named datetime
(I guess that we must re-create a virtualenv)
Window actions from dashboard¶
