Hello I just started messing around with RoR yesterday. I have a simple
little data entry app I''m learning on currently. I just set it up with
the
scaffold command and then used rake to make the db for me.
I have the fields all set up as "string" so they all by default from
the
scaffold use this same text boxes in the new.html.erb file
Code:
<% form_for(@beer) do |f| %>
<p>
<b>Name</b><br />
<%= f.text_field :name %>
</p>
My question is what is the do |f| actually doing. What is |f| referring to?
Also how can I use a grouping of radio buttons to submit information as well
as a select box with set options? (I want to have a "yes",
"no", and
"maybe") radio group for one of my fields and I want a select box with
the
US States in it.
I have looked up the form stuff and all i could get it to do was display a
radio button that did nothing when submitted. - I think this is probably my
lack of understanding of ''f.''
I know it has to be a simple little thing and I look like a real noob for
asking - but hey, I am a noob! I''m really excited about learning more
RoR as
I go on - its really fun so far.
Thanks!

In a nutshell it is an object that knows the the object you''re manipulating is beer. You can create your own subclasses of Formbuilder that display things in particular ways.

Hi Truong, This question is appropriate for rubyonrails-talk not rubyonrails-core. Core is for discussing development of the Rails framework itself.
