diff between redirect_to :action and calling action/rend

Thanks for the quick response, Frederick.


In first case the URL in the browser will say:


and in the second it will say:


But otherwise the net result of what code is processed and what content
is displayed is the same?


....uhm... not exactly.

- redirect_to makes the browser load a new page, and the result is the
same as if the user manually nagivated to this URL or entered it in the
address field of his browser.
so to stick to your example: once the browser has requested the new
page he has been redirected to (controller/list), the "list" action
will be executed, and then the corresponding view will be parsed and
filled with the data made available to it in the action.

- render will only render the view of the "list" action (list.rhtml)
without calling the "list" action first. So you would have to make some
data availabe in the index action that can be parsed in the "list" view
file, which would not be very DRY (Don't repeat Yourself)
