The Jinja template for the ‘choose templates’ page is now pulling in
data from a lot of diparate places in order to work out what to show. As
we add more logic about what to show (in order to make the live search
work) it’s going to get harder to have all this logic in the Jinja
template.
This commit refactors it back into Python where we have more language
features for managing complex logic.
It’s a bit weird to call this file a model, in that it’s dealing with
some presentational logic, rather than just data. Conceptually it’s more
like a view model[1].

It feels like a solid reckon that knowing what’s in a folder before you
click on it will help you navigate around.
However, what do you show in a folder if you’re filtering by template
type? We think that:
- if you’re not filtering you should see all folders, even empty ones
- if you’re filtering you should only see folders that will get you to
relevant templates
This matches what happens when you filter templates, we don’t ‘grey out’
the non-email templates, we hide them completely.
The logic then extends to how we describe the contents of a folder, ie
we won’t count its subfolders if they don’t contain templates of the
type we’re looking for. This means that however you see the folder
described (eg ‘3 templates, 1 folder’) will match what you see when you
click into it.
‘Upload recipients’ and ‘Send to one recipient’ have always been
slightly clunky phrases.
Now that basic view jumps straight into the ‘Send to one recipient’
flow there’s no way for users to get to the ‘Upload recipients’ flow.
By adding a link to it from the ‘Send to one recipient’ flow it’s
possible for users of basic view to access it.
But we don’t want to introduce too much inconsistency between basic view
and admin view because users will be migrating from one to another. They
might also be talking to their manager, who wouldn’t be able to tell
them where to click if they were looking at two completely different
interfaces.
This also means that we can keep the left-hand navigation in basic view
nice and simple with the two options (‘Templates’ and ‘Sent messages’),
rather than trying to introduce something like ‘Send one message’ and
‘Send lots of messages’ later on.
Let users create/edit/delete letter templates.
Let them upload a CSV file or send a test against a letter template.
Big assumption at the moment is that addresses only have one line, and
therefore one column in the CSV file.
For the button on the check page, we need to be able to say ‘1 text message’ or
‘55 emails’. We already have the logic to do this on the dashboard (101 text
messages sent), and it’s already in a component. So this commit makes the check
page use the same component.
