Question

目前我正在循环显示每个帖子并在该循环内循环以显示所有相关的回复。但是目前所有回复都出现在每个董事会的每个帖子下。

我如何只显示与每个帖子相关的回复？

resources :boards, :path => '' do
    resources :posts, :path => 'thread' do
      resources :replies

class BoardsController < ApplicationController
  def show
    @board = Board.friendly.find(params[:id])
    @boards = Board.all
    @replies = Reply.all
  end

class PostsController < ApplicationController
  def show
    @board = Board.friendly.find(params[:board_id])
    @boards = Board.all
    @replies = Reply.all
    @post = Post.includes(:board).where('boards.slug' => params[:board_id]).friendly.find(params[:id])
  end

class Board < ActiveRecord::Base
  has_many :posts
  has_many :replies, through: :posts
  include FriendlyId
  friendly_id :name, use: :slugged
  accepts_nested_attributes_for :posts, :replies
end

class Post < ActiveRecord::Base
  belongs_to :board
  has_many :replies, dependent: :destroy
  accepts_nested_attributes_for :replies
  include FriendlyId
  friendly_id :pid, :use => :scoped, :scope => :id
end

views / boards / show：

    <% @board.posts.find_each do |post| %>
    <%= post.subject %>
      <%= post.name %> 
      <%= post.email %> 
      <%= post.created_at %>
      No.<%= post.pid %>
    <%= link_to "[reply]", board_posts_path(@board, @post)%>
      <br>
      <%= post.comment %><br><br>
<% render "replies/replies" %>
    <% end %>

视图/回复/ _replies：

<% @replies.each do |reply| %>
    <p>
      >><%= reply.name %>
      <% reply.created_at %>
      <%= reply.email %> 
      <%= reply.subject %>
      <%= reply.created_at.strftime("%m/%d/%Y(%a) %I:%M:%S ") %>
      No.<%= reply.pid %>
    <br>
      <%= reply.comment %>
    </p>
<% end %>

Answer 1

您不需要在控制器级别设置回复，因为回复属于帖子。你可以通过post.replies获得给定帖子的所有回复

在你看来

@posts.each do |post|
  replies = post.replies // get all the replies that belongs to this post
  replies.each do |reply|
    reply.attribute
  end
end

Answer 2

由于您只想在_replies中显示相关回复，请不要使用通用@replies，请在那里使用post：

视图/板/显示：

...
<% render "replies/replies", locals: {post: post} %>

视图/回复/ _replies ：

<% post.replies.each do |reply| %>
  ...

仅显示发布的回复
