Hello,

I was studying Rails source and at this point:

def process(request, response, method = :perform\_action, \*arguments)  
#:nodoc:  
response.request = request

```
    initialize_template_class(response)
    assign_shortcuts(request, response)
    initialize_current_url
    assign_names

    log_processing
    send(method, *arguments)

    send_response

```

I have a question.

“send(method, \*arguments)” this calls action of a controller, right?  
But if there’s no ‘render’ in action - how does it automatically call  
render and renders the template for the action?

Thanks a lot

not quite - (at least in the common) case, the method that gets called  
is perform\_action, which calls default\_render if you have not called  
render.

Sweet,

Thanks 🙂
