view_paths=(paths)
click to toggle source
Whenever setting view paths, makes a copy so that we can manipulate them in instance objects as we wish.
# File lib/action_view/lookup_context.rb, line 116 def view_paths=(paths) @view_paths = ActionView::PathSet.new(Array(paths)) end
with_fallbacks() { || ... }
click to toggle source
Adds fallbacks to the view paths. Useful in cases when you are rendering a :file.
# File lib/action_view/lookup_context.rb, line 140 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
Protected Instance Methods
detail_args_for(options)

Compute details hash and key according to user options (e.g. passed from render).
# File lib/action_view/lookup_context.rb, line 161 def detail_args_for(options) return @details, details_key if options.empty? # most common path. user_details = @details.merge(options) if @cache details_key = DetailsKey.get(user_details) else details_key = nil end [user_details, details_key] end
