- sqlalchemy.sql.expression.case must include an else statement.
- clearly define list of columns for inbound_sms_history insert, getting the list from InboundSmsHistory.__table__.c was causing data type errors.
- remove relationships when not needed, the foreign key relationship is established in the creation of the column. This will get rid of the warnings referenced here: http://sqlalche.me/e/14/qzyx.
- update queries now that he user relationship in ServiceUser db model has been removed.
- move the check that a template is archived to the view instead of the dao method. The check was clearing the session before the version history could be done.
Deleting notifications in the night tasks still needs to be
investigated. The raw sql is causing an error.

had to go through the code and change a few places where we filter on
template types. i specifically didn't worry about jobs or notifications.
Also, add braodcast_data - a json column that might contain arbitrary
broadcast data that we'll figure out as we go. We don't know what it'll
look like, but it should be returned by the API
We want a way of getting the hidden precompiled template from admin,
so this adds an endpoint which gets the template or creates it if it doesn't
exist. The function to get or create the hidden template already existed
but has been moved to the template DAO now that it is used in more
places.
The behaviour of stacking the version decorators does not work as
expected.
What you would expect to happen is that each decorator causes a history
row to be written for its respective model object.
What actually happens is that the first decorator adds history records
to the database session, but then causes the database session to commit.
This means that subsequent uses of this decorator find a clean session,
and therefore no changes to copy to their respective history tables.
This commit changes the intended use of the decorator so that it is only
used once per function, and accepts multiple definitions of what to
record history for. This way it can record everything that needs to go
into the history before doing anything that would risk flushing the
session.
When a template is archived, it should no longer belong to any folder.
If we don’t do this it will make it very hard to delete folders later
(because folders can only be deleted if they have no templates or folders
inside them).
We originally tried to check if the link between a template and folder
should be removed with
`if template.archived and template.folder:`
instead of using `if template.archived:`. However, this caused issues
because checking `template.folder` flushes the session. Since the
session is no longer dirty, the versioning decorator doesn't work as
expected and doesn't create a new row in `TemplateHistory`.
Updated jsonschema to Draft7, this allowed a conditional validation on subject, if template_type == 'email' or 'letter' then subject is required.
This version is backward compatible with Draft4.
When creating TempalteRedacted, I've built the dict depending on if the created_by or created_by_id exists.
New redis keys are partitioned per service per day. New process is as
follows:
* require a count of days to filter by. Currently admin always gives 7.
* for each day, check and see if there's anything in redis. There won't
be if either a) redis is/was down or b) the service didn't send any
notifications that day
- if there isn't, go to the database and get a count out.
* combine all these stats together
* get the names/template types etc out of the DB at the end.
Filtering out hidden templates requires all existing templates to
have `hidden` flag set, which can only be done by a migration after
the code that sets the flag to `False` by default for new templates
has been released.
This removes the filtering logic until the migration has been released.
The history was not being updated properly, we think this is because the declaritive attribute is not being set propery by the property.
When reply_to: None it will update the service_letter_contact_id, but not the service_letter_contact, we think when the history_meta is build the history class and checking if the value is updated it depends which attribute it is checking first.
In order to fix this issue, there is a new dao method to update the reply_to on the Template and insert a new Template history.
Currently templates are ordered by the newest created first. This made
sense when, after creating a new template, you were landed on the page
that listed all the templates. In other words, you needed to see
confirmation of the thing that you’ve just done.
Now (since https://github.com/alphagov/notifications-admin/pull/1195)
you get landed on the page for just that template. So you always see
the template you’ve just created, no matter how the list of templates is
ordered. So we are free to change the order of the templates.
Ordering by time created is not great, because it gives users no control
over which templates appear first. For example, our research reported
this from one team:
> One frustration they have is that when you add a new template it
> automatically goes to the top of the list. To get round this, whenever
> they add a new template they delete all of the existing ones and start
> again because they want to keep their templates in numerical order.
> They'd like to be able to control the order of templates in the list.
We _could_ give people some sort of drag-and-drop template ordering
thing. But this feels like overkill. I think that alphabetical order is
better because:
- it’s easily discoverable – anyone who wants to know how a list is
ordered can quickly tell just by looking at it
- it’s universal – everyone knows how alphabetical ordering works
- it’s familiar – this is how people documents on their computer are
ordered; there’s no new UI to learn
- it’s what users are doing already – from the same service as above:
> They number their templates 1,2a, 2b, 3a etc
So this commit changes the ordering from newest created first to
alphabetical.

Implementation notes
---
I refactored some of the tests here. I still don’t think they’re great
tests, but they’re a little more Pythonic now at least.
I also added a sort by template type, so that the order is deterministic
when you have, for example, an email template and a text message
template with the same name. If you have two text message templates with
the same name you’re on your own.
If passing in `redact_personalisation` to the template update endpoint,
we should mark that template permanently as redacted - this means that
we won't ever return the personalisation for any notifications for it.
This is to be used with templates containing one time passwords, 2FA
codes or other sensitive information that you may not want service
workers to be able to see.
This is implemented via a separate table, `template_redacted`, which
just contains when the template was redacted.
Cache expires every 10 minutes, but will help with the every 2 second query, especially when a job is running.
There is some clean up and qa to do for this yet
history-meta's dynamic magic is insufficient for templates, where we
need to be able to refer to the specific history table to take
advantage of sqlalchemy's relationship management (2/3rds of an ORM).
So replace it with a custom made version table.
Had to change the version decorator slightly for this
When you add a new template, it’s probably the one that you want to do
subsequent stuff with. But it’s also helpful to see the template in
context (with its siblings) to understand that there are multiple
templates. So we don’t want to do what we do in
https://github.com/alphagov/notifications-admin/pull/648
for adding a new template.
But we _can_ make your brand-new template appear first by always
ordering by when the template was created.
This also removes the confusion caused by having `updated_at` affecting
order, and causing the templates to move around all the time.
It is also discovered that columns that have a default value and use the version mixin must set the value when creating the db object before the insert otherwise the history table will be missing the default value.
Updated the templates_history.created_by_id with a value where missing, using the current version of the template for this value.
Update templates_history.archived to false. This is okay as we do not yet have a way to set this value to true.
Removed the versions attribute from the TemplateSchema, there is not a need for this column.
Update notifications/sms|email endpoint to send the template version to the queue.
Update the process_job celery talk to send the template version to the queue.
When the send_sms|send_email task runs it will get the template by id and version.
Created a data migration script to add the template_vesion column for jobs and notifications.
The existing jobs and notifications are given the template_version of the current template.
There is a chance this is the wrong template version, but deemed okay since the application is not live.
Create unit test for the dao_get_template_versions method.
Rename /template/<id>/version to /template/<id>/versions which returns all versions for that template id and service id.
