Rails Favorite_posts：“无法找到带有ID的Post”

Question

BLUF:尝试创建一个Favorite_posts特性；我可以通过手动设置Rails控制台中的ActiveRecord来验证它是否工作，

但是我创建的链接给出了一个错误：“找不到没有ID的Post”

表格：

<% if logged_in? %>
  <% unless current_user.favorite_posts.exists?(id: @post.id) %>
    <%= link_to favorite_posts_path(post_id: @post), method: :post do %>
      <span class="glyphicon glyphicon-star-empty"></span>
    <% end %>
  <% else %>
    <%= link_to favorite_post_path(@post), method: :delete do %>
      <span class="glyphicon glyphicon-star"></span>
    <% end %>
  <% end %>
<% end %>

财务主任：

class FavoritePostsController < ApplicationController
    before_action :logged_in_user, :set_post

  def create
    Favorite.create(favorited: @post, user: current_user)
    respond_to do |format|
      format.html
      format.js
    end
  end

  def destroy
    Favorite.where(favorited_id: @post.id, user_id: current_user.id).first.destroy
    respond_to do |format|
      format.html { redirect_to @user }
      format.js
    end
  end

  private

  def set_post
      @post = Post.find(params[:post_id] || params[:id])
  end

end

模型：

class Post < ApplicationRecord

  belongs_to :user

class Favorite < ApplicationRecord
  belongs_to :favorited, polymorphic: true
  belongs_to :user
end

class User < ApplicationRecord

    extend FriendlyId
    friendly_id :name

    has_many :posts, dependent: :destroy
    has_many :favorites
    has_many :favorite_posts, through: :favorites, source: :favorited, source_type: 'Post'

路线：

  resources :users do
    collection do
      match 'search' => 'users#index_gyms', via: [:get, :post], as: :search
    end

    member do
      get :following, :followers
      get :favorite_posts
    end
  end

  resources :favorite_posts,      only: [:create, :destroy]

Answer 1

修正:我从一个_post部分项目中重构出了这个表单，当我把它放回去的时候，它工作得很好。我认为后端只是为那个控制器设置的，而且我不太关心如何正确地重构它

Answer 2

你试过把@post.id而不是@post传递到你的网址，

favorite_posts_path(id: @post.id)
