Hi All,
I''ve got a view "app\views\home\start..rhtml" that invokes a
partial
template with:
< %= render :partial => "customer/list" % >
(spaces inserted between % and its associated angle bracket here and in the
following code).
The partial view "app\views\customer\_list.rhtml" creates a link with
the
code:
< %= link_to(c.name,
:controller => ''customer'',
:action => ''show'',
:id => c.id)
% >
I''d like to replace the code in the partial view with a one-line
helper:
< %= link_to_customer(c) % >
and define the helper in the module in
"app\helpers\customer_helper.rb"
with:
def link_to_customer(c)
link_to(c.name,
controller => ''customer'',
action => ''show'',
id => c.id)
end
When I tried this, I got:
undefined method `link_to_customer'' for
#<#<Class:0x3cb2710>:0x3cb2278>
Any ideas of a way to get this going?
Thanks in advance,
Richard

Your link_to_customer helper method is not mixed into the home controller, and is therefore not available. You have some choices: 1) Mix-in the customer helper methods into your other controller with ''helper'': helper CustomerHelper 2) Move your link_to_customer definition to application_helper.rb so it will be available to all controllers/views. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi Curtis, Great explanation!! Especially the alternative options!! Thanks a lot.

Hi Curtis, Woops. I''m not out of the woods yet.> I''m assuming you are calling this partial while in the home controllerRight.> 2) Move your link_to_customer definition to application_helper.rb so it > will be available to all controllers/views.Chose this option, definition same as before. Substituted my helper invocation in app\views\customer\_list.rhtml (line 12) and got error messages (looks like it''s looking for ''show'' in home rather than customer folder): NameError in Home#start Showing app/views/customer/_list.rhtml where line #12 raised: undefined local variable or method `action'' for #<#<Class:0x3cd7520>:0x3cd7418> Extracted source (around line #12): 9: <% @customers.each do |c| %> 10: <tr> 11: <td> 12: <%= link_to_customer(c) %> 13: </td> 14: <td align="right"> <%= c.balance %> </td> 15: <td> <%= c.last_issue_dt %> </td> Maybe I have to shift to the other option. I thought I''d wait to see if you had an approach to make the chosen option work. Maybe it''s not worth wasting your time on it.

Hi Curtis, Thanks again. My excuse (we always need one when we screw up, don''t we), is that I''m a Ruby and Rails newbie. So I''m insufficiently sensitive to those pesky little colons. Incidentally, I copied the code I started with from somewhere (but missed the colons), and that source didn''t use any braces to form the hash. So I left them out to see whether it would work without them, wish it did. I infer from this success that the link_to method''s prototype requires a hash and the Ruby interpreter accepts the hash-like elements as components of the needed hash. Just a theory. No need to spend any more time on me. Again, thank you very much for pushing me along. Best wishes, Richard Curtis Summers wrote:> Richard wrote: > > Hi Curtis, > > > > Woops.
