Instance Method Details



  

    #_normalize_args(action = nil, options = {})   (private)
  



  

    

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 78



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)   (private)
  



  

    

Normalize options.

# File 'actionpack/lib/abstract_controller/rendering.rb', line 93



def _normalize_options(options) # :doc:
  options
end


  








  

    #_process_options(options)   (private)
  



  

    

Process extra options.

# File 'actionpack/lib/abstract_controller/rendering.rb', line 98



def _process_options(options) # :doc:
  options
end


  








  

    #render(*args, &block)  
  



  

    

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


  



  [ GitHub ]


  

  


# File 'actionpack/lib/abstract_controller/rendering.rb', line 23



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.


  



  [ GitHub ]


  

  


# File 'actionpack/lib/abstract_controller/rendering.rb', line 50



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.

def render_to_string(*args, &block)
  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.
