I have a view with a table that contains sortable links as headings.
Here is the code used to create these sortable links in the
application_helper:
module ApplicationHelper
  def sort_link_helper(text, param)
    key = param
    key += "_reverse" if @params[:sort] == param
    link_to(text, :controller => ''sales_orders'', :action
=> ''list'',
:sort => key )
  end
end
Here is the code in my controller where I call the sort_link_helper
function:
  <tr>
           <th><%= sort_link_helper ''Number'',
''id'' %></th>
           <th><%= sort_link_helper ''Sold To'',
''sold_to'' %></th>
           <th><%= sort_link_helper ''Ship To'',
''ship_to'' %></th>
           <th><%= sort_link_helper ''Rep'',
''rep'' %></th>
           <th><%= sort_link_helper ''Description'',
''description'' %></th>
           <th><%= sort_link_helper ''Amount'',
''amount'' %></th>
           <th><%= sort_link_helper ''Ship Date'',
''ship_date'' %></th>
           <th>Current Status</th>
  </tr>
The problem is that sometimes, when I click one of these links to sort
the table by that field, I get the following error:
 Showing app/views/sales_orders/list.rhtml where line #29 raised:
Invalid argument
Extracted source (around line #29):
26:            <th><%= sort_link_helper ''Rep'',
''rep'' %></th>
27:            <th><%= sort_link_helper
''Description'', ''description''
%></th>
28:            <th><%= sort_link_helper ''Amount'',
''amount'' %></th>
29:            <th><%= sort_link_helper ''Ship Date'',
''ship_date'' %></th>
30:            <th>Current Status</th>
31:   </tr>
32:
It is maddeningly inconsistent.  Sometimes, I can just do a refresh and
it''ll work fine.  Sometimes I have to refresh several times before I
can
get it to work.  Also, the line number causing the error will be
different sometimes, but it''s always one of the lines with the
sort_link_helper in it.
Any ideas on how I can get this fixed?
Thanks!

I have narrowed the problem down a bit:
def sort_link_helper(text, param)
    key = param
    #the following line is the culprit.  I''m not sure what I''m
doing
wrong here.
    key += "_reverse" if @params[:sort] == param
    link_to(text, :controller => ''sales_orders'', :action
=> ''list'',
:sort => key )
  end
What is wrong with the line above that adds ''_reverse'' to the
key?

Should be without the @: def sort_link_helper(text, param) key = param key += "_reverse" if params[:sort] == param link_to(text, :controller => ''sales_orders'', :action => ''list'', :sort => key ) end -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
