Dear Tim,
I am sorry to annoy but I have pain to setup chanext-scheming.
I successfully perform those operation:
/1.//#sudo chown -R `whoami` /usr/lib/ckan/default/
/2./#. /usr/lib/ckan/default/bin/activate//
/3.//#/cd /usr/lib/ckan/default/src//
/4.//#/pip install -e
‘git+https://github.com/ckan/ckanext-scheming.git#egg=ckanext-scheming’//
/5./#cd ./ckanext-scheming//
/6./#pip install -r
/usr/lib/ckan/default/src/ckanext-scheming/requirements.txt//
But I really do not understand how to configure it following this page
https://github.com/ckan/ckanext-scheming
I do not understand how to modify the configuration. Is the file
/etc/lib/ckan/default/production.ini?
I try to modifiy the following (In green, it what I added):
ckan.plugins = stats text_view image_view recline_view*scheming_datasets*
# module-path:file to schemas being used
*scheming.dataset_schemas = ckanext.spatialx:spatialx_schema.json
ckanext.spatialx:spatialxy_schema.json*
# will try to load "spatialx_schema.json" and "spatialxy_schema.json"
# as dataset schemas
#
# URLs may also be used, e.g:
#
# scheming.dataset_schemas = http://example.com/spatialx_schema.json
# Preset files may be included as well. The default preset setting is:
*scheming.presets = ckanext.scheming:presets.json*
# The is_fallback setting may be changed as well. Defaults to false:
*scheming.dataset_fallback**= false *
After adding those line, I reload apache2 and the web page display an
Internal Server Error. I also tried
*scheming.dataset_schemas = ckanext.spatialx:spatialx_schema.json *
*or*
**scheming.dataset_schemas =* ckanext.spatialx:spatialxy_schema.json*
But none works
I also edited the file
*/usr/lib/ckan/default/src/ckanext-scheming/ckanext/scheming/ckan_dataset.json*
and modified a field name, a label but I could not see a change on the
web interface.
I am new with CKAN, could tell me a bit more about the configuration and
how to add new field?
Many thank
Cheers
Pierre
