Currently it’s not possible for a screen reader user to know which
financial year they’re looking at. From the accessibility report:
> The financial year links are contained in a navigation region -
> tabbing or arrowing through only reads out the links, not the main
> information of "2016 to 2017 financial year" - that information is
> vital for understanding the page content.
This problem also applies to other pages which use the `pill` component,
which is effectively tabbed navigation (that reloads the page rather
than showing or hiding content on the page).
There are specific ARIA attributes that can be used to mark up a
navigation as being tabbed. This commit:
- adds those attributes
- makes the selected ‘tab’ visible to screenreaders and keyboard
focusable
- adds a visual focus indicator to the selected tab
- adds `id`s to the parts of the page that are controlled by the tabs so
that they are labelled as such
This also means changing the pill component from being a `<nav>` to a
`<ul>` because `tablist` is not a valid `role` for a `nav`.
Mostly follows the example here:
http://accessibility.athena-ict.com/aria/examples/tabpanel2.shtml
In pages specific to a service (e.g. dashboard and sub pages) the title
needs to distinguish which service it applies to. This is mainly to give
context to screen reader users who could be managing multiple services.
Implementing this uses template inheritance:
`page_title` includes `per_page_title` includes `service_page_title`
‘GOV.UK Notify’ is inserted into every page title.
Pages that set `service_page_title` get the service name inserted too.
Right now we tell people that the usage page is for the current
financial year. This is a lie – it’s for all time.
So this commit calls through to the API to get the stats for (by
default) the current financial year.
We already do this for the monthly breakdown, this just does the same
thing for the yearly totals.
It also adds navigation to show the data for other financial years:
- previous so you can go back and see your usage and verify that the
bill you’re about to pay is correct
- next so that you can check what your SMS allowance is going to be
before you actually get into it
Basically:
- shows all the months from start of given financial year to now or end
of given financial year (whichever is earliest)
- shows a breakdown of free and paid text messages for each of these
months
Depends on:
- [x] https://github.com/alphagov/notifications-api/pull/699
Make it clear that this section is about what you’ve used, ie your usage
Click ‘breakdown’ to see how the maths is done, and what time period it
covers.
Takes the number of emails and SMS fragments sent from:
https://github.com/alphagov/notifications-api/pull/273
Using these numbers it’s possible to show:
- how much of your allowance is left
- or how much you have spent
For now the allowance and rates are hard coded.
Only for users that have manage service.
