Ruby-SDK - 2.0.0-beta1
March 29th, 2018
This major release of the Optimizely SDK introduces APIs for Feature Management. It also introduces some breaking changes listed below.
### New Features * Introduces the `is_feature_enabled` API to determine whether to show a feature to a user or not. ``` enabled = optimizely_client.is_feature_enabled('my_feature_key', 'user_1', user_attributes) ```
* You can also get all the enabled features for the user by calling the following method which returns a list of strings representing the feature keys: ``` enabled_features = optimizely_client.get_enabled_features('user_1', user_attributes) ```
* Introduces Feature Variables to configure or parameterize your feature. There are four variable types: `Integer`, `String`, `Double`, `Boolean`. ``` string_variable = optimizely_client.get_feature_variable_string('my_feature_key', 'string_variable_key', 'user_1') integer_variable = optimizely_client.get_feature_variable_integer('my_feature_key', 'integer_variable_key', 'user_1') double_variable = optimizely_client.get_feature_variable_double('my_feature_key', 'double_variable_key', 'user_1') boolean_variable = optimizely_client.get_feature_variable_boolean('my_feature_key', 'boolean_variable_key', 'user_1') ```
### Breaking changes * The `track` API with revenue value as a stand-alone parameter has been removed. The revenue value should be passed in as an entry of the event tags map. The key for the revenue tag is `revenue` and will be treated by Optimizely as the key for analyzing revenue data in results. ``` event_tags = { 'revenue'=> 1200 }
optimizely_client.track('event_key', 'user_id', user_attributes, event_tags) ```
