  @view_paths.exists?(*args_for_lookup(name, prefixes, partial, keys, options))
end
Also aliased as: template_exists?

  @view_paths.find(*args_for_lookup(name, prefixes, partial, keys, options))
end
Also aliased as: find_template
find_all(name, prefixes = [], partial = false, keys = [], options = {}) click to toggle source
# File lib/action_view/lookup_context.rb, line 113
def find_all(name, prefixes = [], partial = false, keys = [], options = {})
  @view_paths.find_all(*args_for_lookup(name, prefixes, partial, keys, options))
end
find_template(name, prefixes = [], partial = false, keys = [], options = {}) click to toggle source
Alias for: find
template_exists?(name, prefixes = [], partial = false, keys = [], options = {}) click to toggle source
Alias for: exists?
view_paths=(paths) click to toggle source

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 104
def view_paths=(paths)
  @view_paths = ActionView::PathSet.new(Array.wrap(paths))
end
with_fallbacks() { || ... } click to toggle source

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

# File lib/action_view/lookup_context.rb, line 123
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) click to toggle source

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

# File lib/action_view/lookup_context.rb, line 144
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
