view_paths=(paths)

Whenever setting view paths, makes a copy so that we can manipulate them in instance objects as we wish.

# File actionview/lib/action_view/lookup_context.rb, line 111
def view_paths=(paths)
  @view_paths = ActionView::PathSet.new(Array(paths))
end
with_fallbacks()

Adds fallbacks to the view paths. Useful in cases when you are rendering a :file.

# File actionview/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

detail_args_for(options)

Compute details hash and key according to user options (e.g. passed from render).

# File actionview/lib/action_view/lookup_context.rb, line 161
def detail_args_for(options) # :doc:
  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
