Rails - Feb 2005 - Input naming conventions

Can somebody please direct me to a good reference for the "rails" way
to
do forms?  I notice that some inputs have square brackets in their names 
and some use underscores and I''m a little confused.

On a related note, I wanted to create a text field that saved its value 
when the form was reloaded.  I figured I could use this:

<%= text_field "user", "username", { :size => 30,
:value =>
@params[''user''][''username''] } %>

But the rendered output was:

<input id="user_username" name="user[username]"
size="30" size="30"
type="text" value="" value="posted value" />

Since the value attribute got duplicated, the posted value wasn''t 
displayed.  Any ideas?

Thanks,
Carl

Hi Carl,

Try this:

<%= text_field "user", "username", { :size => 30 }
%>

Rails will take care of filling the value when reloading.
