Instance Public methods
render(*args, &block) Link
Normalizes arguments and options, and then delegates to render_to_body
and sticks the result in self.response_body
.
Supported options depend on the underlying render_to_body
implementation.
# File actionpack/lib/abstract_controller/rendering.rb, line 26 def render(*args, &block) options = _normalize_render(*args, &block) rendered_body = render_to_body(options) if options[:html] _set_html_content_type else _set_rendered_content_type rendered_format end _set_vary_header self.response_body = rendered_body end
render_to_body(options = {}) Link
Performs the actual template rendering.
render_to_string(*args, &block) Link
Similar to render
, but only returns the rendered template as a string, instead of setting self.response_body
.
If a component extends the semantics of response_body
(as ActionController
extends it to be anything that responds to the method each), this method needs to be overridden in order to still return a string.
rendered_format() Link
Returns Content-Type
of rendered content.
view_assigns() Link
This method should return a hash with assigns. You can overwrite this configuration per controller.
Instance Private methods
_normalize_args(action = nil, options = {}) Link
Normalize args by converting render "foo"
to render action: "foo"
and render "foo/bar"
to render file: "foo/bar"
.
# File actionpack/lib/abstract_controller/rendering.rb, line 73 def _normalize_args(action = nil, options = {}) # :doc: if action.respond_to?(:permitted?) if action.permitted? action else raise ArgumentError, "render parameters are not permitted" end elsif action.is_a?(Hash) action else options end end
_normalize_options(options) Link
Normalize options.
