Hi all,  
I encountered a issue when using redirect\_to:

in new.html.erb

\<%= error\_messages\_for :user %\>

in my controller, when I use render :action =\> ‘new’, the error msg  
can display correctly.  
but when I change render :action =\> ‘new’ to redirect\_to signup\_url  
the error msg can’t display.

Appreciate for your help.

redirect\_to tells your browser to request the page.  
So you get a totally new request and all your model object states are  
lost

Is there any way that I can keep the object states when using  
redirect\_to ?

Thanks.
