ZedDB Model Transformers

ZedDB model data items can have standard “transformers” attached to them – actions to be performed on the data item just before it is saved to the underlying storage system. You can create or delete model item transformers. A model item’s transformers are listed within its response data set.

To create a new Model Transformer you submit the required parameters of the transformer type with the model item UUID that you are attaching a transformer to. Whatever items you send within the :transformer Hash are passed through to the ZedAPI untouched. There is no client side validation within this gem.

ZedDB::ModelTransformers.create(:user_key => user['user_key'], :item => { :uuid => item['uuid'] },
                                :transformer => { :code => 'UP' })

To delete a Model Transformer:

ZedDB::ModelTransformers.delete(:user_key => user['user_key'], :uuid => transformer['uuid])

From each of these requests the Zedkit::Client class will return a response hash for your reference, if needed, or as applicable to the request. If there was a HTTP 401 or 404 you will get a nil response. This indicates a security failure or that an UUID is incorrect, not attached the user’s account, or non-existent.

For each request you can also pass a block to process the response directly:

ZedDB::ModelTransformers.delete(:user_key => user['user_key'], :uuid => transformer['uuid]) do |result|
end
