Module: Blacklight::Searchable

Extended by:
ActiveSupport::Concern
Included in:
Catalog
Defined in:
app/controllers/concerns/blacklight/searchable.rb

Overview

The Searchable module can be included onto classes that need to initialize a SearchService. There are three dependencies you must provide on the including class. Typically these would be provided by Blacklight::Controller

1. search_state
2. blacklight_config

Additionally, the including class may override the search_service_context method to provide further context to the SearchService. For example you could override this to provide the currently signed in user.

# File 'app/controllers/concerns/blacklight/searchable.rb', line 23

def search_service
  search_service_class.new(config: blacklight_config, search_state: search_state, user_params: search_state.to_h, **search_service_context)
end

#search_service_context ⇒ Hash

Override this method on the class that includes Blacklight::Searchable to provide more context to the search service if necessary. For example, if your search builder needs to be aware of the current user, override this method to return a hash including the current user. Then the search builder could use some property about the current user to construct a constraint on the search.

Returns:

  • (Hash) —

    a hash of context information to pass through to the search service
