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

@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

@comment = Comment.new
@post = Post.find(params[:id])
@comments = @post.comments
respond_to do |format|
