[ckan-dev] json preview

Wed May 22 10:29:45 UTC 2013

Thank you Dominik.

it improves the error feedback, and now i found out the problem: the json
resources at stake do not support HEAD requests, which are used in
controller.py
f.i.
http://data.police.uk/api/crimes-street/all-crime?lat=52.629729&lng=-1.131592&date=2011-08

maybe something to consider, as it is quite frequent (apparently) to lack
HEAD support.

best,

--p.
