This commit adds a page to view a single broadcast. This is important
for two reasons:
- users need an audit of what happened when, and who else was involved
in approving or cancelling a broadcast
- we need a place to put actions (approving, cancelling) on a broadcast
so that you can confirm details of the message and the areas before
performing the action
Shows the broadcasts with the longest time still to live at the top. At
the moment this will be the same as the newest broadcasts, so we may
want to revisit this sort order when we have broadcasts of variable
duration.
For no-longer-live broadcasts we show the most-recently-finished at the
top, whether it finished naturally or was cancelled.
Currently this is a `get` request from the dashboard. Once we have a page
for viewing an individual broadcast it should probably show there
instead and be a `get`/confirm/`post` loop like for deleting a template.
Shows current and previous broadcasts. Does not add a page for viewing
an individual broadcast.
Broadcasts are split into live and previous.
Draft broadcasts are excluded from the dashboard.
This commit removes the code the puts areas into the session and instead
creates and then updates a draft broadcast in the database.
This is so we can avoid session-related bugs, and potentially having a
large session when we start adding personalisation etc.
Once a broadcast is ready to go it is set to `broadcasting` straight
away with no approval. We’ll revisit this as we learn more about how
users might want to manage who can create and approve broadcasts.
The tests are a bit light in terms of checking what’s on the page, but
clicking through the pages is probably good enough for now.
