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



  

    

Normalize args by converting render “foo” to render :action => “foo” and render “foo/bar” to render :file => “foo/bar”. :api: plugin


  



  [ GitHub ]


  

  


# File 'actionpack/lib/abstract_controller/rendering.rb', line 79

    #_normalize_options(options)  
  



  

    

Normalize options. :api: plugin

end


  








  

    #_normalize_render(*args, &block)  
  



  

    

Normalize args and options. :api: private

    #_process_format(format, options = {})  
  



  

    

Process the rendered format. :api: private

# File 'actionpack/lib/abstract_controller/rendering.rb', line 107



def _process_format(format, options = {})

    #_process_options(options)  
  



  

    

Process extra options. :api: plugin

def _process_options(options)
  options
end


  








  

    #render(*args, &block)  
  



  

    

Normalize arguments, options and then delegates render_to_body and sticks the result in self.response_body. :api: public


  



  [ GitHub ]


  

  


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



def render(*args, &block)
  options = _normalize_render(*args, &block)
  self.response_body = render_to_body(options)
  _process_format(rendered_format, options) if rendered_format
  self.response_body
end


  








  

    #render_to_body(options = {})  
  



  

    

Performs the actual template rendering. :api: public


  



  [ GitHub ]


  

  


# File 'actionpack/lib/abstract_controller/rendering.rb', line 48



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 Action Controller extends it to be anything that responds to the method each), this method needs to be overridden in order to still return a string. :api: plugin

def rendered_format
  Mime::TEXT

    #view_assigns  
  



  

    

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

    hash[name.slice(1, name.length)] = instance_variable_get(name)
  }
