Including the range of years of your content

If you need to use the range of years in which content was created, first ensure that anything you want to count is using the special key published to store the date (it is fine to duplicate the date if you are already using a different key).

Add the following to your

from flourish import helpers

def global_context(self):
    return {
        'publication_range': helpers.publication_range(self),

GLOBAL_CONTEXT = global_context

This makes a variable global.publication_range available to all of your templates, which contains a string much like "2012–2016".

You can use this in your templates like so:

  <p>Copyright {{global.publication_range}} {{}}.</p>
