Usage

To use as a view, no further setup is needed; the 'Gallery' type should be available for resources after installing the plugin.

Interfaces

The IGalleryImage interface allows plugins to override settings.

from ckan.plugins import SingletonPlugin, implements
from ckanext.gallery.plugins.interfaces import IGalleryImage

class YourPlugin(SingletonPlugin):
  implements(IGalleryImage)


  def image_info(self):
    '''
    Return info for this plugin. If resource type is set,
    only datasets of that type will be available.
    '''
    return {u'title': u'Text',
            u'resource_type': [u'csv', u'tsv'],
            u'field_type': [u'text']}


  def get_images(self, field_value, record, data_dict):
    '''
    Process images from a single record to return custom metadata.
    The field_value depends on the image field you choose.
    '''
    images = [{
      u'href': field_value[u'url'],
      u'thumbnail': field_value[u'url'].replace(u'preview', u'thumbnail'),
      u'record_id': record[u'_id']
    } for img in field_value]
    return image
