[ckan-dev] ckan-dev Digest, Vol 30, Issue 71

Sun Apr 28 01:12:56 UTC 2013

Thanks for answering my question. The reason why it could not step to the
breakpoint in datastore_create is that I used a wrong curl command, I am
really sorry for that. And I deeply appreciate the mail that told me about
the structure of the tables in datastore. Thanks again for all your help.
