We’re going to let people pass in fairly complex polygons, but:
- we don’t want to store massive polygons
- we don’t want to pass the CBCs massive polygons
So this commit adds a step to simplify the polygons before storing them.
We think it’s best for us to do this because:
- writing code to do polygon simplification is non-trivial, and we don’t
want to make all potential integrators do it
- the simplification we’ve developed is domain-specific to emergency
alerting, so should throw away less information than
There’s a bit more detail about how we simplify polygons in

This gives us some extra confidence that there aren’t any problems with
the data we’re getting from the other service. It doesn’t address any
specific problems we’ve seen, rather it seems like a sensible precaution
to take.
Other systems we’re working with won’t easily be adapted to emit JSON
instead of CAP, so it’s less work for us to do that conversion.
This commit adds to code to parse the XML and turn it into a dict that
we can work with, including converting the polygon string into native
Python lists.
Add different error message for email and text if content is too long.
Use utils version with is_message_too_long method implemented for email templates.
depending on the notification type.
Up until now, only sms messages could get message-too-long error,
but now we also need to validate the size of email messages, so
the message content needs to be tailored to the notification type.

Formats the content of the template at the time of creating the event.
This means that any downstream code (eg Celery tasks) can assume the
content is already formatted correctly.
Also, these downstream tasks don’t know which template the broadcast
was created from, so if we support personalisation in the future this is
the most sensible place to bring together the template and the
personalisation.

I had to re-create some of the deleted code from utils for stuff like
formatting the timestamp to the CAP standard.
