previously the back link went to choosing a library.
Now, if you view a district from a county, go back to the county page.
Otherwise, go back to the top level of the library.
If there is a search term when the page loads, a
statement about the results is added to the
searchbox label.
All subsequent searches are announced via an aria
live-region.
At the moment there are some areas which have:
- a `count_of_phones` value of `None`
- no sub-areas
This is wrong, but until we fix the data the phone counting code needs
to handle this.
This commit:
- adds the `or 0` in the right place (where it will catch these areas
with missing data)
- adds a test which checks these areas, and compares them to other kinds
of areas
This is a better name for the module because it’s:
- not just constants, there’s a method in here now
- only stuff to do with populations, not other kinds of constants
Includes:
- fixes for the cancel button, when selecting a
template type (after clicking 'New template')
- making the folder icon black, to match the text,
on template list items
We have some radios using the GOVUK Frontend
radios component in this app. They are version
2.x.x though so this bumps their styles to version
3.x.x to get the new focus style.
It has a hover colour so needs the focus colour
re-defined.
The `overflow: hidden` was clipping the black
underline of the focus style on the prev/next
links. This assumes it was only there to contain
the 2 floating links so replaces it with a
clearfix, which does the same without clipping the
underline.
We need to give people a better feel for the consequences of
broadcasting an alert. We’ve seen in research that some users will
assume it is subscription based, or opt-in, rather than going to every
phone in the area.
I reckon that the most effective way to communicate this is to put some
numbers next to the areas, to give people an idea of how many people
will get alerted.
We can estimate how many phones are in an area by:
- taking the population of all electoral wards in that area
- multiplying it by the percentage of people who own an internet
connected phone[1]
The Office for National Statistics publish both these datasets.
The number of people who own an intenet connected phone varies a lot by
age. Since the population data for each ward is broken down by age we
can factor this in. Simplified, the calculation looks like this:
- take the _Abbey_ ward of _Barking and Dagenham_
- in this ward there are 26 people aged 80
- 40% of people over 65 have an internet-connected phone
- therefore 10 of these 80-year-olds would be likely to receive a
broadcast
- (repeat for all other ages)
These numbers won’t be exact, but should be enough to give people a feel
for the severity of what they’re about to do. We can see if they acheive
this aim in user research.
1. This is a proxy for the number of people who are likely to have a 4G
capable phone, because only 4G capable phones will be receiving
broadcasts to begin with
