Dear Jenny

The extension worked fine for me following the instructions.

Maybe you have some typo in the name of the plugin somewhere, this happened to me once and I got a similar error.
You can check the names match in the following files:

- In development.ini you should have "scheming_datasets" in the plugins settings:
## Plugins Settings
ckan.plugins = stats text_view image_view recline_view [other plugins] scheming_datasets

- It should be the same name as in your plugins setup.py file:
   """
    [ckan.plugins]
    scheming_datasets=ckanext.scheming.plugins:SchemingDatasetsPlugin
    scheming_groups=ckanext.scheming.plugins:SchemingGroupsPlugin
    scheming_organizations=ckanext.scheming.plugins:SchemingOrganizationsPlugin
    scheming_test_subclass=ckanext.scheming.tests.plugins:SchemingTestSubclass

    [paste.paster_command]
    scheming=ckanext.scheming.commands:SchemingCommand
    """,

- Just in case, don't forget to install the extension (python setup.py develop) 

I hope it helps, good luck!
Lucia

Hi, Carl:
 
Yes, I did this in the production.ini file:
 
scheming.dataset_schemas = https://gist.githubusercontent.com/happyrainb/3b21cbdc7e64a1a2311ed54abc4ed5dd/raw/15f44d4f0fc755217f736b7d8e287ade5e3b0ba7/ckan-cusp-schema.json
 
Then I changed back to the default scheme which used to work well.
scheming.dataset_schemas = https://raw.githubusercontent.com/ckan/ckanext-scheming/master/ckanext/scheming/ckan_dataset.json
 
 
But now the error message changed to:

Hi Jenny,

ÿ
Did you enable the plugin on the ckan.plugins line in your production.ini?
ÿ
Cheers,
Carl

I added the http path of my schema in the /etc/ckan/default/production.ini.
