Rails form tag not going to custom delete route, going to standard delete route instead

Question

I am trying to delete a collection of items based upon checkboxes. I created a custom route. The destroy_multiple route.

  Rails.application.routes.draw do
  resources :projects do
    resources :lists, shallow: true do
      member do
        post :sort
      end
      resources :items, shallow: true
    end
  end

  resources :items do
    collection do
     delete :destroy_multiple, :as => :destroy_multiple
    end
  end
  resource :react
end

When I run rake routes I get this as a result

                       GET    /items/:id(.:format)                      items#show
                       PATCH  /items/:id(.:format)                      items#update
                       PUT    /items/:id(.:format)                      items#update
                       DELETE /items/:id(.:format)                      items#destroy
                 react POST   /react(.:format)                          reacts#create
             new_react GET    /react/new(.:format)                      reacts#new
            edit_react GET    /react/edit(.:format)                     reacts#edit
                       GET    /react(.:format)                          reacts#show
                       PATCH  /react(.:format)                          reacts#update
                       PUT    /react(.:format)                          reacts#update
                       DELETE /react(.:format)                          reacts#destroy

And my form tag looks like this..

<%= form_tag url_for(:controller => 'items', :action => 'destroy_multiple'), :method => 'delete' do %>

  <ul class="list-group sortable" data-update-url="<%= sort_list_path(list) %>">
    <%= render list.items %>
  </ul>
  <%= submit_tag("Delete Items") %>
<% end %>

I am not getting any errors but it is not going to the right controller action it ends up at just the destroy action for a singular item. Here is my controller. class ItemsController < ApplicationController

  before_action :set_item, only: [:edit, :update]

  def create
    @list = List.find(params[:list_id])
    @item = @list.items.create params[:item].permit(:content)
  end

  def edit
  end

  def update
    @item.update_attributes(params[:item].permit(:content))
  end

  def destroy
    @item.destroy
  end

  def destroy_multiple

    debugger
  end

  private

  def set_item
    @item = Item.where(id: params[:id]).first!
  end

end

I just want the form submission to go to the custom destroy_multiple action. I appreciate any help. Thank You.

Answer 1

You can try to follow, at first you create route like original destroy action

resources :items do
 collection do
   #delete :destroy_multiple, :as => :destroy_multiple
   delete '/destroy_multiple/:id(.:format)' => 'items#destroy_multiple', constraints: { id: /.*/ }, as: :destroy_multiple
  end
end

Now run rake routes you get the something like this (not tested route but code is right now)

destroy_multiple_items DELETE /items/destroy_multiple/:id(.:format)         items#destroy_multiple

Now you can try to delete using checkbox

def destroy_multiple
   Item.where(id: params[:id]).destroy_all
   # redirect
end

Hope to help

As per @JoshHumphrey my error was having multiple routes. My updated route file is

Rails.application.routes.draw do
  resources :projects do
    resources :lists, shallow: true do
      member do
        post :sort
      end
      resources :items, shallow: true do 
        collection do
           delete :destroy_multiple, :as => :destroy_multiple
        end 
      end
    end
  end


  resource :react
end

And I updated the form a bit to pass the list id down so here is the form

<%= form_tag(destroy_multiple_list_items_path(list_id: list.id),method: :delete,remote: true) do %>
  <ul class="list-group sortable" data-update-url="<%= sort_list_path(list) %>">
    <%= render list.items %>
  </ul>
  <%= submit_tag("Delete Selected",  :class => "btn btn-warning") %>
<% end %>

Everything else stayed the same! Thanks for the help Josh.
