Helpers related to template lookup using the lookup context information.
# File lib/action_view/lookup_context.rb, line 130 def exists?(name, prefixes = [], partial = false, keys = [], options = {}) @view_paths.exists?(*args_for_lookup(name, prefixes, partial, keys, options)) end
# File lib/action_view/lookup_context.rb, line 121 def find(name, prefixes = [], partial = false, keys = [], options = {}) @view_paths.find(*args_for_lookup(name, prefixes, partial, keys, options)) end
# File lib/action_view/lookup_context.rb, line 126 def find_all(name, prefixes = [], partial = false, keys = [], options = {}) @view_paths.find_all(*args_for_lookup(name, prefixes, partial, keys, options)) end
Whenever setting view paths, makes a copy so we can manipulate then in instance objects as we wish.
# File lib/action_view/lookup_context.rb, line 117 def view_paths=(paths) @view_paths = ActionView::PathSet.new(Array.wrap(paths)) end
Add fallbacks to the view paths. Useful in cases you are rendering a :file.
# File lib/action_view/lookup_context.rb, line 136 def with_fallbacks added_resolvers = 0 self.class.fallbacks.each do |resolver| next if view_paths.include?(resolver) view_paths.push(resolver) added_resolvers += 1 end yield ensure added_resolvers.times { view_paths.pop } end
Compute details hash and key according to user options (e.g. passed from render).
# File lib/action_view/lookup_context.rb, line 157 def detail_args_for(options) return @details, details_key if options.empty? # most common path. user_details = @details.merge(options) [user_details, DetailsKey.get(user_details)] end
