[ckan-dev] Extending IAuthFunctions and public access

[Hendrik Bunke]

Hi Lucia,

you can use a decorator provided by plugins.toolkit: auth_allow_anonymous_access
See
http://docs.ckan.org/en/latest/extensions/plugin-interfaces.html#ckan.plugins.interfaces.IAuthFunctions
for more details.

regards
hendrik
