This commit extends the `ajax_block` component to take a `dict` of
partials, from which it can select the partial matching its `key`
argument and print its HTML to the page.
This means that the same markup is only rendered in one place, rather
than in two (individually in the JSON endpoint and as `include`s in the
parent template).
This is less repetitive than typing out the HTML with all its attributes
every time.
It also lets us wrap up the idea of ‘finished’ as a parameter, so the
AJAX code will only be initiated when it’s needed, eg if a job is still
processing.
Previously, the AJAX update for the dashboard was returning a big blob
of JSON with one key.
This commit splits it up to return:
- one key for each section of the page
- each containing a smaller chunk of HTML rendered from a partial
The jobs page was already working this way (pretty much) but just needed
a little tweaking to get it the same.
Currently, when we update a section of the page with AJAX we replace the
entire HTML of the section with the new HTML. This causes problems:
- if you’re trying to interact with that section of the page, eg by
inpecting it, clicking or hovering an element
- (probably) for screenreaders trying to navigate a page which is
changing more than is necessary
This commit replaces the call to `.html()` with a pretty clever library
called diffDOM[1]. DiffDOM works by taking a diff of the old element and
the new element, then doing a patch update, ie only modifying the parts
that have changed.
This is similar in concept to React’s virtual DOM, while still allowing
us to render all markup from one set of templates on the server-side.

For email jobs, the template needed to look up the service to work out
the email_from and from_name.
`service` used to be a variable passed through to the view. Now every
veiw gets `current_service` instead.
This is a quick fix to make things work.
When a table is showing the contents of a CSV file, it should look
something like a spreadsheet.
The minimally skeuomorphic way to do this is by adding row numbers.
This commit doesn’t
- make the row numbers monospace (it’s barely noticeable and doesn’t
reflect what actual spreadsheets do)
- make the first column heading ‘Row’ (again, doesn’t reflect how actual
spreadsheets work, and takes up more valuable space)
The template for viewing a job was not getting all the variables it needed in
order to display an email template. Hadn’t noticed this before, because email
templates require more variables than SMS templates.
This commit fixes that bug.
This is a first go at having the job page update without refreshing.
The approach I’ve taken is to do all the rendering of HTML on the server side,
rather than use a Javascipt templating engine like mustache. This ensures that
we don’t have to maintain two sets of templates.
So the approach is to split the job page into partials. These partials can then:
- be included in the job page to render the whole page
- be rendered indivudually and then returned as a blob of HTML inside a JSON
response
Then I’ve added a Javascript module which looks for areas of the page that should
be reloaded. For each area of the page it will poll a URL and re-render that
section of the page when it gets new HTML. It implements some throttling so that
API calls will never happen more frequently than 0.67 times/second.
