向URL而不是Rails API中的ID进行删除请求

Question

i'm wondering if anyone can give me any advice.

I'm currently writing a rails API and although it doesn't seem like a best practice, rather than performing a DELETE call to

localhost:3000/products/:id

id rather make it to

localhost:3000/products/:url

and pass in the URL to be deleted, however i've currently got this but I keep getting a routing error.

DELETE '/products/:url', to: 'products#destroy'

is my current route for this, it is also specified above my

resources :products

sections.

My whole routes file:

AppName::Application.routes.draw do      
  resources :features do
  resources :feature_links
  end

  resources :wishlist_items

  resources :data_feeds
  get '/get_data_feeds', to: 'data_feeds#get_feed_url', as: 'feed_url'

  resources :genders

  resources :trends

  resources :sub_categories

  resources :color_tags

  resources :colors

  resources :categories

  delete '/products/:url', to: 'products#destroy'

  resources :products do
    member do
      get 'buy'
      post 'wish'
    end
  end
end

Any ideas? Thanks in advance

If the url i'm sending the delete request to is http://localhost:3000/products/www.test.com I get the error No route matches [DELETE] "/products/www.test.com" if the url I sent the delete request to is http://localhost:3000/products/:url I get the error Couldn't find Product with 'id'=:url

My Destroy method code:

 def destroy
    @product = Product.find(params[:url])
    @product.destroy
    respond_with(@product, status: 200)
 end

I think Rails is considering your URL parameter as the specification of the format of the response. You can override the constraints of the parameter as follows:

constraints: { url: /[^\/]+/ }

This will make sure that the URL parameter can be anything except for / . The whole route should look like this:

delete "/products/:url", to: "products#destroy", constraints: { url: /[^\/]+/ }, as: :products_destroy_with_url

And use it like this:

link_to "Destroy", products_destroy_with_url_path("www.test.com"), method: :delete
