为社交化Ruby on Rails创建视图

Question

社会化宝石似乎拥有我可能需要或想要的所有模型/结构。但是，没有其他任何东西可以帮助您完成项目。由于文档很少，我的问题是独一无二的。我必须转向stackoverflow。

首先，让我先谈谈我使用这个宝石的方向。我想使用public_activity gem的跟踪功能创建包含社交Feed的主题区域。在仪表板上，用户将看到他们最近的活动和过去的评论。我想要做的是弄清楚我应该如何将系统结构化为DRY并且易于自定义/添加功能。

当前项目包括

posts_controller.rb

class PostsController < ApplicationController
  # GET /posts
  # GET /posts.json

  before_filter :authenticate_user!, only: [:create, :new, :edit, :destroy]
  def dashboard
    @posts = current_user.posts

    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @posts }
    end
  end

  # GET /posts/1
  # GET /posts/1.json
  def show
    @comment = Comment.new
    @post = Post.find(params[:id])
    @comments = @post.comments

    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @post }
    end
  end

  # GET /posts/new
  # GET /posts/new.json
  def new
    @post = Post.new

    respond_to do |format|
      format.html # new.html.erb
      format.json { render json: @post }
    end
  end

  # GET /posts/1/edit
  def edit
    @post = Post.find(params[:id])
  end

  # POST /posts
  # POST /posts.json
  def create
    @post = Post.new(params[:post])
    @post.user = current_user

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

  # PUT /posts/1
  # PUT /posts/1.json
  def update
    @post = Post.find(params[:id])

    respond_to do |format|
      if @post.update_attributes(params[:post])
        format.html { redirect_to @post, notice: 'Post was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: "edit" }
        format.json { render json: @post.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /posts/1
  # DELETE /posts/1.json
  def destroy
    @post = Post.find(params[:id])
    @post.destroy

    respond_to do |format|
      format.html { redirect_to posts_url }
      format.json { head :no_content }
    end
  end
