javascript - 有一个响应按钮

Question

我是 RoR 的新手，我需要一些建议

为了解释一般概念，用户可以创建私有(private)的食谱(帖子)。然后，用户可以发布添加价格和数量的帖子。一面墙引用了所有最后发布的帖子。

现在，我打算制作一个按钮，将我的私有(private)帖子发布到公共(public)墙上。而且我不确定这样做的方法。 Pushing button

理想情况下，我可以为每个新发布编辑价格和编号

我目前正在构建帖子、成分、评论、用户和用户个人资料。

应该为此操作生成脚手架还是向我的帖子添加新闻变量？

如果你想看我的代码=

后 Controller :

class PostsController < ApplicationController
  before_action :authenticate_user!
  before_action :set_post, only: [:show, :edit, :update, :destroy]
  before_action :owned_post, only: [:edit, :update, :destroy]

  # GET /posts
  # GET /posts.json
  def index
    @posts = Post.all.order("created_at DESC")
end  


  # GET /posts/1
  # GET /posts/1.json
  def show

  end

  # GET /posts/new
  def new
    @post = current_user.posts.build
  end

  # GET /posts/1/edit
  def edit
  end

  # POST /posts
  # POST /posts.json
  def create
    @post = current_user.posts.build(post_params)

    respond_to do |format|
      if @post.save
        format.html { redirect_to @post, notice: 'Post was successfully created.' }
        format.json { render :show, status: :created, location: @post }
      else
        format.html { render :new }
        format.json { render json: @post.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /posts/1
  # PATCH/PUT /posts/1.json
  def update
    respond_to do |format|
      if @post.update(post_params)
        format.html { redirect_to @post, notice: 'Post was successfully updated.' }
        format.json { render :show, status: :ok, location: @post }
      else
        format.html { render :edit }
        format.json { render json: @post.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /posts/1
  # DELETE /posts/1.json
  def destroy
    @post.destroy
    respond_to do |format|
      format.html { redirect_to posts_url, notice: 'Post was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_post
      @post = Post.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def post_params
      params.require(:post).permit(:user_id, :title, :description, :image, ingredients_attributes: [:id, :name, :_destroy])
    end

    def owned_post  
  unless current_user == @post.user
    flash[:alert] = "That post doesn't belong to you!"
    redirect_to root_path
  end
end  

end

个人资料/节目:

  <div class="row profile-header">
    <div class="col-md-6">
      <div class="img-circle">
        <%= profile_avatar_select(@user) %>
      </div>
    </div>
    <div class="col-md-6">
      <div class="user-name-and-follow">
        <h3 class="profile-user-name">
          <%= @user.pseudo %>
        </h3>
        <span>
          <% if @user == current_user %>
            <%= link_to 'Edit Profile', edit_profile_path(@user.pseudo) %>
              
            
          <% end %>
        </span>
      </div>
      <p class="profile-bio">
        <%= @user.bio %>
      </p>
      <div class="user-statistics">
        
      </div>
    </div>
  </div>
</div>

<p>
          <%= pluralize @user.posts.count, 'post' %>
        </p>
<div>
<%-@posts.each do |post| %>

<div class="toca">
   <%= render 'posts/post2', post: post %>
   <% end %>
</div>
  </div>

和 post2 :

<div class="row">
<%-@posts.each do |post|%>

<div class="post">
  <div class="form-group text-center">
    <h3> <%=post.title%></h3>
  </div>

  
 <p> Posted by : <%= link_to post.user.pseudo, profile_path(post.user.pseudo) %>,  <%= time_ago_in_words(post.created_at) %> ago </p>
  <div class="image text-center">
    <div class="image-border">
     <%= link_to (image_tag post.image.url(:medium), class: 'img-responsive'), post_path(post)%>
    </div>
  </div>

  
 
    
 

  <div class="btn-group" role="group" aria-label="...">
  <%= link_to '-  Pusher  - ', post, class: 'btn btn-primary' %>
  </div>
  
  
  </div>
  <% end %>
 </div>
 </div>

所以如果你有任何建议可以向我建议最适合你的方法

Answer 1

<%= link_to '-  Pusher  - ', post, class: 'btn btn-primary' %>

您可以创建一个新方法来更新属性:

<%= link_to '-  Pusher  - ', post, class: 'btn btn-primary', controller: "post", action: :go_public %>

然后就可以写代码公开了:

def go_public(params)
  @post = Post.find(id)
  @post.update_attributes(public_boolean: true)
end
