module BlacklightAdvancedSearch
Returns a lambda that you can use with a before_filter in your CatalogController to catch and redirect query params using the old style, used prior to blacklight_advanced_search 5.0.
This can be used to keep any old bookmarked URLs still working.
before_filter BlacklightAdvancedSearch::RedirectLegacyParamsFilter, :only => :index
Constants
- VERSION
Public Class Methods
Utility method used in our solr search logic. Like Rails Hash#deep_merge, merges 2 hashes recursively, including nested Arrays and Hashes. Unlike Rails Hash#deep_merge:
-
will NOT merge nil values over existing ones
-
will NOT merge (non-FalseClass) blank values
-
WILL deduplicate values from arrays after merging them
@param [Hash|HashWithIndifferentAccess] source_hash @param [Hash|HashWithIndifferentAccess] new_hash @return [Hash] the deeply merged hash @see Rails deep_merge apidock.com/rails/v4.2.1/Hash/deep_merge @example new_hash = BlacklightAdvancedSearch.deep_merge
(h1, h2)
# File lib/blacklight_advanced_search.rb, line 26 def self.deep_merge(source_hash, new_hash) source_hash.deep_merge(new_hash, &method(:merge_conflict_resolution)) end
this one side-effects the first param @see deep_merge @deprecated use `new_hash = BlacklightAdvancedSearch.deep_merge
(h1, h2)` instead
# File lib/blacklight_advanced_search.rb, line 33 def self.deep_merge!(source_hash, new_hash) source_hash.deep_merge!(new_hash, &method(:merge_conflict_resolution)) end
the arguments are set by what the Rails Hash.deep_merge supplies the block
# File lib/blacklight_advanced_search.rb, line 38 def self.merge_conflict_resolution(_key, old, new_value) return old if new_value.nil? return old if new_value.respond_to?(:blank?) && new_value.blank? && !new_value.is_a?(FalseClass) return old | new_value if old.is_a?(Array) && new_value.is_a?(Array) new_value end
# File lib/blacklight_advanced_search/version.rb, line 3 def self.version @version ||= File.read(File.join(File.dirname(__FILE__), '..', '..', 'VERSION')).chomp end
