• Use postelections as the list to be grouped
• Use 'grouper' rather than pulling the date off the first election object.
• Default text if there are no elections

Hi @mrwilson. Thanks for having a look at this and sorry none of us had a chance to review it before the local elections last week.

I've had a quick look at your changes on my local copy. Your changes fix the problem correctly where there are >=1 upcoming elections, but your check for the case where there are 0 elections doesn't pick up the condition correctly. I still get "On , registered voters in {postcode} will be able to vote in 0 elections".

You can fix it by changing the check to either
if not header_elections_by_date or
if postelections.count == 0.
Can you update and then we'll merge.

Thanks
