Rails - Jul 2006 - How to display data using helpers and collections

## application_helper.rb
def name_field(object, options = {} )
  html = ""
  html << "Title : " + select(object, ''title'')
  html << "Given Names :" + text_field(object,
''given_names''
  html << "Family Name :" + text_field(object,
''family_name''
  html
end

## index.rhtml
<div id="list_doctors">
  <%= render :partial => ''doctor'', :collection =>
@doctors %>
</div>

## _doctor.rhtml
<%= name_field "doctor#{doctor.id}" %>

How do I display the data from the doctor?

I have try this and it does not work
<%= name_field "doctor[#{doctor.id}]" %>
NameError: `@nok[1]'' is not allowed as an instance variable name

And
<%= name_field "doctor_#{doctor.id}" %>
But this does not display the data for the current doctor in the 
collection

Any ideas?

Do this within _doctor.rhtml
<% @doctor = doctor %>
<%= name_field @doctor %>

It will work.

Thanks aj

I tried that and now I got this error
`@#<Doctor:0x34f0f68>'' is not allowed as an instance variable
name

Any other idea?

Cheers

Ok I found a solution :)
<%= name_field "doctor" %>

But know, my question relates to the other one I did earlier in other 
post. How can I number the objects? I mean, this returns
<input id="doctor_given_names" name="doctor[given_names]"
type="text">

but if I want many doctors in the page, all the fields will have the 
same ID, therefore I will not be able to differentiate between them.

I mean
<input id="doctor_1_given_names"
name="doctor[1][given_names]"
type="text">
or
<input id="doctor??_given_names"
name="doctor??[given_names]"
type="text">

How can I do that?

Thanks

PS name_field "doctor[1]" does not work

You mean your doctors collection has no ID in it?

for iteration based ID, you would have to keep it as a global variable 
as partial for collection means calling the partial many times with a 
single object.

<http://api.rubyonrails.com/classes/ActionView/Helpers/ 
FormHelper.html> explains:

If the object name contains square brackets the id for the object  
will be inserted. Example:

   <%= text_field "person[]", "name" %>

?becomes:

   <input type="text" id="person_<%= @person.id
%>_name" name="person
[<%= @person.id %>][name]" value="<%= @person.name
%>" />
