[ckan-dev] Overriding helper functions?

Fri Jan 30 19:25:49 UTC 2015

Hi Andrew,

You can certainly monkey patch the methods. Simply write your own and
overwrite that function from ckan.lib.helpers. I seem to remember doing
something like that here:

https://github.com/open-data/ckanext-wet-boew/blob/master/ckanext/wet_boew/plugins.py#L37

Of course, you should be careful as this approach is a hack by any measure.
