Question

如何干我看起来像这样的路线

  post 'products/sum', to: 'product#sum'
  post 'products/subtract', to: 'product#subtract'
  post 'cars/sum', to: 'car#sum'
  post 'cars/subtract', to: 'car#subtract'
  post 'houses/sum', to: 'house#sum'
  post 'houses/subtract', to: 'house#subtract'

类似

  post '%w{products,cars,houses}/%{sum subtract}', to: '%w{products,cars,houses}#%{sum subtract}'

我是否只想知道以上路线是否属于DRYable，如果是，可以如何做到这一点。

Answer 1

只需一个选项

%i(products cars houses).each do |item|
  resource item, only: [] do
    post :sum
    post :subtract
  end
end

这会产生

➜ rake routes | grep -E "(house|car|product)"

     sum_products POST   /products/sum(.:format)         products#sum
subtract_products POST   /products/subtract(.:format)    products#subtract
         sum_cars POST   /cars/sum(.:format)             cars#sum
    subtract_cars POST   /cars/subtract(.:format)        cars#subtract
       sum_houses POST   /houses/sum(.:format)           houses#sum
  subtract_houses POST   /houses/subtract(.:format)      houses#subtract

DRY路由与不同的控制器
