[ckan-dev] How to install ckanext-scheming

Wed Sep 21 15:34:29 UTC 2016

The .activate just ensures you are in the virtual environment that ckan dev is installed in.

You follow a very similar install process for almost all ckan extensions. Some have requirements.txt and/or dev-requirements.txt that need installing. Some extensions require supporting DB tables to be created (QA for example). Generally though, if you learn the procedure below, you can install almost all extensions without issue.

Dear Tim,

Thank for your help.

When I firstly install ckan, I installed it from source and I used that command during the process

. /usr/lib/ckan/default/bin/activate

I reinstalled my PC with a new Ubuntu 14.04 installation and I installed successfuly CKAN from the package. I did not needed to use the above command.

I supposed, even if I installed CKAN from package, I can use the above command and use pip?
I will try to install ckanext-scheming later or tomorrow.

Cheers
Pierre

Pierre,

cd /usr/lib/ckan/default/src

pip install -e "git+https://github.com/ckan/ckanext-scheming.git#egg=ckanext-scheming"

cd ./ckanext-scheming

pip install -r /usr/lib/ckan/default/src/ckanext-scheming/requirements.txt

·         Any issues, sudo the previous command *

As the rest of the instructions say, insert scheming_datasets in to your plugins line

Add in the scheming.presets section in to your config, just under the plugins section

Add in a scheming.dataset_fallback = false

Add in a scheming.dataset_schemas = ckanext.scheming:schemaname.json

Where schemaname.json is the JSON file that describes your schema (ie. list of metadata elements). As an example, I think there is camel.json and ckan_dataset.json

Create a similar template file called dataset.json and it will load as the default 'new dataset' schema/template.

Sorry - the json files are stored in ./ckanext-scheming/ckanext/scheming/.......

Hope the above helps

Tim
