</div>

My view rhtml contains the following

\<% for contactaddress in @contact\_address %\>  
\<%= text\_field “contactaddress”, “addr\_line1”, “size” =\> 50 %\>\</  
\<%end%\>

In the above code @contactact\_address contains several contact address  
objects. The for loop iterates each of them and tries to show the value  
of model attribute addr\_line1 in the text input box.

The problem

In the rhtml it creates a text input field but it doesn’t show value of  
addr\_line1 in the text input box.

What is wrong here? Thanks in advance for your help…

Regards  
Venu

Try doing \<% for @contactaddress in @contact\_addresses %\>

Ryan…an instance variable won’t be allowed…I got error message  
saying this.

Thanks

text\_field expects the first parameer to be the name of an instance  
variable.  
Either create an instance variable with that name, or use  
text\_field\_tag or look into fields\_for which allows you to escape that  
convention.
