I am using a namespace

```
 map.namespace :admin do |admin|
  admin.resources :repairs
 end

```

which puts my repairs\_controller.rb and my repairs views into admin  
subdirectory

when I use an Helper method repaired\_tables(@repair) in my  
views/admin/repairs/show.html.erb

I get an error "undefined method `repaired\_tables’ "

I tried to put my repairs\_helper inside a subdirectory too, … no change

Where shoudl I put it ? anything to add ?

thanks for your lights
