[ckan-dev] Datapusher causes AttributeError (select_entity_from()) in datacats install

[Wiebke Toussaint]

Hey!


I'm a newbee to CKAN, datacats, docker and coding, but after a lot of hacking and brain-wrecking I've managed to install an almost working instance of ckan with datacats at energydata.uct.ac.za


One problem: my setup fails when ever I try to login to my site. After searching for similar issues I can trace it back to a problem with datapusher.



My original set up is as follows:

  1.  VS running Ubuntu 14.04
  2.  Install done following http://docs.datacats.com/guide.html (source install with most up to date master)
  3.  Created datacats environment inside my virtual environment project folder with
     *   datacats create --ckan latest aerdb
  4.  Deployed with
     *   datacats reload --production --address=137.158.163.71 --site-url http://energydata.uct.ac.za aerdb 80
  5.  Checked that I've got SQLAlchemy v0.9.6 correctly installed

My setup responds the same as referenced here by mattfullerton https://github.com/ckan/ckan/commit/a4de57e5, however this more recent discussion https://github.com/datacats/datacats/issues/334 seems to indicate that the issue is resolved when using ckan latest.


I've managed to get my installation running by changing select_entity_from() back to select_from(), but it seems strange to me and I'd prefer not to use a workaround for a resolved issue.


Any insight would be appreciated.


All the best,

Wiebke
