Howdy,
Reading about the "index" option for checkboxes and text fields, I
understand that it will create values like this:
<text_field "person", "name", "index" =>
1>
becomes
<input type="text" id="person_1_name"
name="person[1][name]" value="<%= @
person.name <http://person.name> %>"/>
However, shouldn''t it really evaluate to this instead:
<input type="text" id="person_1_name"
name="person[1][name]" value="<%@person[1].name
%>"/>
I''ve been losing my mind over this. In my program, @person is a hash,
so
@person[1].name resolves very nicely, but @person.name
<http://person.name>simply disappears. Do I write a horrible hack that
says "@
person.name <http://person.name> = @person[1].name" before each field
is
printed? That just seems so ugly. I''m hoping there''s an easy,
obvious way
that I''m missing.
Another thought I had is extending FormHelper to do this for me. Looking at
its code, it seems my problem lies here:
def object
@template_object.instance_variable_get "@#{@object_name}"
end
Would I want to change object to be something like:
def object(*index)
if (!index)
return @template_object.instance_variable_get "@#{@object_name}"
else
return @template_object.instance_variable_get
"@#{@object_name}[#{index}]"
end
end
Hoping I missed something really obvious, or that the above extension
isn''t
lunatic.
-Mike

Wouldn''t this work: i = 0 @people.each do |person| <text_field "person", "name", "index" => i++> end On Sun, 2005-10-23 at 11:51 -0400, Mike DeGraw-Bertsch wrote:> Howdy, > > Reading about the "index" option for checkboxes and text fields, I > understand that it will create values like this: > > <text_field "person", "name", "index" => 1> > > becomes > > <input type="text" id="person_1_name" name="person[1][name]" value="<% > = @person.name %>"/> > > However, shouldn''t it really evaluate to this instead: > > <input type="text" id="person_1_name" name="person[1][name]" value="<% > = @person[1].name %>"/> > > I''ve been losing my mind over this.

Howdy, Okay, I can work with that. However, how do I then use error_message_on or error_messages_for? Doesn''t it expect instance variables? @people is just a hash, and it won''t recognize ''person''.
