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.
