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.
`Notification.template_history` relationship has been removed but
we want to keep the `template_history` key in existing notification
serializations, so we serialize it from `Notifications.template`.
This keeps the data format the same, but both `template` and
`template_history` keys will now contain data from the `TemplateHistory`
instance.
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.
There are some Null template_ids in the production database which was
causing a failure as the stats_template_usage_by_month has a constraint
that it should not be null. This update only adds populated template_ids
- Updated Celery task
- Add a new test to test for null template_ids and not try to add them
to the stats
- Modified the services_dao to return an int instead of a datetime to
make usage easier and removed the BST function on year as it is not
relevant for year
- Improved tests do there is less logic by ordering the result so there
is less reliance on the template id
- Renamed variable in stats_template_usage_by_month_dao.py to make it
consistent with the method
Currently some pages are timing out due to the time it takes to perform
database queries. This is an attempt to improve the performance by
performing the query against the notification history table once a day
and use the notification table for a delta between midnight and the when
the page is run and combine the results.
- Added Celery task for doing the work
- Added a dao to handle the insert and update of the stats table
- Updated tests to test the new functionality
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.
One of our providers gives us messages with special characters escaped,
ie a newline comes through as `\n`, not a literal newline. We shouldn’t
be showing these backslashes to any of our users. We also have examples
of real inbound messages containing `👍` and `’`, so we should continue
to display these properly.
It’s a bit tricky, because the strings we get from this provider are a
mixture of escape sequences (eg `\n`) and unicode characters (eg `😨`).
So we have to first convert the unicode character `😨` into an escape
sequence, `\U0001f628` in this example. We do this by encoding with
the `raw_unicode_escape` codec:
> Latin-1 encoding with \uXXXX and \UXXXXXXXX for other code points.
> Existing backslashes are not escaped in any way. It is used in the
> Python pickle protocol.
– https://docs.python.org/3/library/codecs.html#text-encodings
Then we turn this back into a string using the `unicode_escape` codec,
which transforms all escape sequences into their literal representations
(eg `\U0001f628` becomes `😨` and `\n` becomes a newline).
by hitting POST /<user_id>/email-code, we create an email two factor
code to send to the user. That email contains a link with a token that
will sign the user in when opened.
Also some other things:
"email verification" (aka when you first create an account) doesn't
hit the API anymore
refactor 2fa code verification and sending to use jsonschema, and share code between sms and email
Die marshmallow die!
- 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`.
