Class Method Details

.add_plugin_object_to_context(plugin_id, context) ⇒ Object

Adds the plugin object to the liquid context object to be used by tags, filters, and drops. This method looks in the :site register for an object which responds to #plugin_object_for_id in order to populate the :plugin_object register. If such an object does not exist, the method simply yields without altering the context object. Otherwise, after yielding, the context object is reset to its previous state.

Parameters:

  • plugin_id (String) —

    the plugin id to use

  • context (Liquid::Context) —

    the liquid context object
