Template helpers

Get the publication year range

from flourish.helpers import publication_range

publication_range(flourish, 'updated')

publication_range(flourish, key) will return a string like 2012–2016, for the years of any source that has a datetime in key. This is useful for creating the copyright line in a site's footer.

The first argument is your flourish instance.

The second argument is which key to use to find the dates. It is optional, and the default is 'published' (which is one of the special keys in Flourish).
