Relationship attribute is not used by the application code, so we
can remove it without replacing it with a TemplateHistory one.
This also updates the foreign key constraint to refer to the composite
primary key for the TemplateHistory records.
TemplateHistory objects need to be connected to the template's
TemplateRedacted record. This requires setting up a new SQLAlchemy
relationship to allow accessing redact_personalisation from
TemplateHistory instances.
We can avoid creating a foreign key in this case by setting up an
explicit `primaryjoin` expression. Since TemplateHistory.id is
created from Template.id and TemplateRedacted.template_id is
already a foreign key to Template.id the foreign key should always
be valid even without a DB constraint.
Notifications.serialize calls `Notifications.template.get_link`, so
we need TemplateHistory objects to generate their API URLs.
This generates a link to the `/v2/` version of the endpoint.
Each notification instance is connected to a specific version of the
template that was used to generate notification content. Template
versions are stored in TemplateHistory, so that's the table we need
to use for Notifications.template relationship.
Currently, using Notifications.template returns the latest template
version, which leads to incorrect content being returned by the API
if the template has been updated.
This change removes Notifications.template_history attribute and
replaces template relationship to refer to TemplateHistory instance
based on the notification's template ID and version.
Currently the 'See templates used by month' report is timing out for
some services due to the query time of the data from notification_history
This is a stats table which will hold the data and will be updated by a
scheduled celery task once a day. This data will be combined with the
'live' data from notifications tables (which will be considerably less)
to form the data of the new report.
- had to update the serialization in the model so that the date time is appended with the UTC timezone
- test has been added to ensure that the schema will validate the response correctly
We want new services, when they do the tour, to see how the service name
they just made shows up in the messages. This is how it (should) work
at the moment (although got broken because of the multiple senders
stuff).
Need to do this before we do the migration now otherwise a new service
could sneak in with this setting still set to `null`.
In future changes, services will be able to control whether their text
messages will be prefixed with the name of their service.
This commit:
- adds a column to store the value of that setting
- makes the service model take notice of it, if it were to have a value
set
It doesn’t:
- provide a way of setting the value of this column
Currently the column can have three values:
- `None` – ignore it (this is what all current services will start as)
and continue to determine whether to prefix messages by looking at the
sender
- `True` – always the service name to the start of text messages
- `False` – never add the service name to the start of text messages
In the future we’ll migrate all services to be either `True` or `False`,
the `None` will go away and all services will have direct control over
the setting.
If the service is sending messages from GOVUK, then its messages should
be prefixed with the service name. Right now this logic is:
- worked out separately in the admin app and API
- isn’t aware of multiple senders
This commit moves the logic to one place (the service model). It does
this in a slightly naive way, in that it only looks at the default
sender, not the actual sender of the message.
In the future this will go away because we’ll move it to being a setting
that’s controlled independently of the service name. But this is the
first step towards that.
fixup! Add prefix SMS with service name to service model
NotificationStatistics was added as a spike but didn't work out as expected. This is finally removing all that unused code.
I'll drop the table in the next PR

In order to work out what a team’s allowance should be, we need to know
what part of government they’re from. We’re going to do this logic in
the admin app and then `POST` the allowance to the API.
So all we need to do with the information that the users give us is
store it against the service, so we have a record. Doesn’t need any
logic doing as a result of it, doesn’t need foreign keying to the
organisations table, etc.
