Instance Public methods
render(*args, &block)

Normalizes arguments, options and then delegates #render_to_body and sticks the result in self.response_body.

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
  self.response_body = rendered_body
end
render_to_body(options = {})

Performs the actual template rendering.

def render_to_body(options = {})
end
render_to_string(*args, &block)

Raw rendering of a template to a string.

It is similar to render, except that it does not set the response_body and it should be guaranteed to always return a string.

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.

  options = _normalize_render(*args, &block)
  render_to_body(options)
end
rendered_format()

Returns Content-Type of rendered content.

def rendered_format
  Mime[:text]
end
view_assigns()

This method should return a hash with assigns. You can overwrite this configuration per controller.

# File actionpack/lib/abstract_controller/rendering.rb, line 64
def view_assigns
  protected_vars = _protected_ivars
  variables      = instance_variables

  variables.reject! { |s| protected_vars.include? s }
  variables.each_with_object({}) { |name, hash|
    hash[name.slice(1, name.length)] = instance_variable_get(name)
  }
end
Instance Private methods
_normalize_args(action = nil, options = {})

Normalize args by converting render "foo" to render :action => "foo" and render "foo/bar" to render :file => "foo/bar".
