* remove from model
* still required when calling POST /service - we just call through
from dao_create_service to add a new annual billing entry.
* removed from POST /service/<id> update_service - if you want to
update/add a new one, use POST /service/<id>/free-sms-fragment-limit
* made sure tests create services with default 250k limit.
- Reverted the Gunicorn worker number to 5 (this should be investigated
further on a well baselined system to compare)
- Enabled REDIS
- Increased the rate limit to 400 req/sec as using early testing
yesterday 450+ was being achieved
- check if service_callback_api exist before putting tasks on queue
- create_service_callback_api in tests before asserting if send_delivery_status_to_service has been called.
- Added the boolean 'crown' column to services and services_history tables
- We populate this column in the same migration script by checking the
'organisation_type' of a service
- Disable Redis as there is a current connection limit of 256 which
could slow down the request if they are all used
- Added statd to methods in the post to help spot any bottlenecks
`create_history` used to initialise an empty model instance and
assign attributes to it one by one. Assigned attributes are
collected by iterating over internal state of the modified record
and stored in a dictionary, so the order in which they are set on
the history instance is undefined.
This works fine for most model instances, but recent changes to the
Template models require `template_type` to be set before `reply_to`,
otherwise Template doesn't know which column to use to persist the
`reply_to` value.
This means that we need to order the attributes when they're being
assigned. We achieved this by defining a constructor for Template
objects that assigns `template_type` first.
In order to make it work with `create_history` we replace individual
`setattr` calls with a single call to the Template constructor which
passes the entire data dictionary as keyword arguments.
This works because all persisted attributes are defined as columns
and SQLAlchemy accepts all column values as constructor arguments.
