[ckan-dev] Modify resource URL

Wed Jun 5 15:10:24 UTC 2013

Hi,

In your first email you mentioned you were using CKAN 1.8 and on your
second 2.0.

If you are using 2.0, form_to_db_schema no longer exists, you need to use

    def create_package_schema(self):
        schema = super(ExampleIDatasetFormPlugin, self).create_package_schema()
        schema['url'].append(my_url_converter)
        return schema

    def update_package_schema(self):
        schema = super(ExampleIDatasetFormPlugin, self).update_package_schema()
        schema['url'].append(my_url_converter)
        return schema

def my_url_converter(value, context):
    value = 'http://opencities.edu'
    return value

Have a look at this for more info:

http://docs.ckan.org/en/ckan-2.0/extensions.html?highlight=idatasetform#ckan.plugins.interfaces.IDatasetForm

Oh, btw, if you are talking about the resource url, not the dataset
url, then you need to modify this field of the schema:

        schema = super(ExampleIDatasetFormPlugin, self).create_package_schema()
        schema['resources']['url'].append(my_url_converter)

Hope this helps,

Adrià
