[ckan-dev] Extending IAuthFunctions and public access - SOLVED

[lucia.espona at wsl.ch]

Sorry Hendrik

I swear I read the manual page at least twice... until the "See ckan/logic/auth/ for more examples.", right before the last paragraph where that with the decorator is explained.

It works now of course :)

Thanks a lot,
Lucia

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
