Hi!  
Unless i am missing something you want to make changes and save them  
back. I think you can collect all the ids of the projects using the  
collect  
statement in Ruby and then run a loop if request.post? with these id and  
for  
each textarea you can just use the Modelname.update method.  
Thanks and regards,  
Swanand.

Swanand,  
Thanks for your reply. Actually I am new to Ruby and web technologies  
too. So sometime not understand the terms. Ok.  
you mean say, I need to post all my project ids for particular user,  
collect them in controller, But how to update that row. I am unable to  
get Modelname.update term.

Regards,
