Question

现在我有一个喜欢按钮，让你喜欢食物。当你尝试与食物不同时，我会收到这个错误：

The action 'destroy' could not be found for UsersController

我不确定为什么要在用户控制器中查找destroy动作。我唯一的猜测是因为按钮在用户显示页面上，所以我认为它默认为该控制器，但我如何从我的投票控制器访问删除方法？

 Shared like form

 <% unless current_user.votes.empty? ||  current_user.votes.pluck(:food_id).include?(food.id) %>
     <%= form_for @vote do |f| %>
       <%= f.hidden_field 'food_id', food.id %>
       <%= f.hidden_field 'user_id', food.user.id %>
       <%= f.submit "Vote", :class => "like_button" %>
     <% end %>
 <% else %>
     <% vote = food.votes.where(user_id: current_user.id).first %>
     <div class="unlike_button">
     <%= button_to "Unlike", vote,  method: :delete %>
 </div>
<% end %>

class VotesController < ApplicationController

def index
 @votes = Vote.all
end

def new
 @vote = Vote.new
end

def create
 @vote = Vote.new(vote_params)

if @vote.save
  puts @vote
    flash[:notice] = "Thanks for voting!"
  redirect_back(fallback_location: root_path)
else
  puts "No"
    flash[:notice] = "Something went wrong"
  redirect_back(fallback_location: root_path)
  end
end

def destroy
   @vote = Vote.find(params[:id])
   if @vote.destroy!
    flash[:notice] = "Unvoted!"
    redirect_back(fallback_location: root_path)
   end
end

private

def vote_params
  params.require(:vote).permit(:food_id, :user_id)
end
end

class Vote < ApplicationRecord
    belongs_to :user
    belongs_to :food
end

Rails：link_to从不同的控制器中删除
