I'm trying to create a simple helper module in rails, and I'm stumped on the following error message from my new person form (app/views/people/new.html.erb):
undefined method `sort' for 97:Fixnum
Extracted source (around line #17):
14: <p>
15: <% nations = { 'United States of
America' => 'USA', 'Canada' => 'Canada', 'Mexico' => 'Mexico', 'United Kingdom' => 'UK' } %>
16: <%= f.label :country %><br />
17: <%= radio_buttons(:person, :country, nations) %>
18:
19: </p>
20: <p>
radio_buttons is a helper module I have created for my view. Here it is (app/helpers/people_helper.rb):
module PeopleHelper
def radio_buttons(model_name, target_property, button_source)
html=''
list = button_source.sort
list.each do |x|
html << radio_buttons(model_name, target_property, x[1])
html << h(x[0])
html << '<br />'
end
return html
end
end
The problem appears to be on the "list = button_source.sort", but I'm not sure why it says the method is undefined. I have been able to use it directly within my view code. Am I not able to use methods like this within helper modules? Do I need to include something?
Thanks for any help!
