Rails - Feb 2006 - How to access param entered through text_field

I''m rendering partial a form comprising several text_field helpers to 
maintain my User model. For example, the email field is:

<p><label for="user_email">Email</label><br/>
<%= text_field ''user'', ''email'', :size
=> ''40'', :maxsize => ''256''
%></p>

In my controller, I know I can assign all the params in the form to my 
user object with ''@user = User.new(params[:user])'', but how
can I assign
individual params? Say I wanted to set the variable email to be the 
contents of the above field. I could recode the partial into pure HTML 
then assign params(''email'') to my variable, but I would rather
stick
with the RoR helpers as it looks cleaner.

You can leave the partial as it is and use:

email = params[:user][:email]

text_field will generate an <input> with the name user[email]. The 
square brackets get parsed and turned into hashes by Rails.

Thanks Philip -  I think I understand it now.
