ActiveRecord::UnknownAttributeError (unknown attribute 'photo' for PublicActivity::Activity.): 
    app/controllers/posts_controller.rb:28:in `create' 

    def create 
    @user = current_user 
    @post = @user.posts.build(post_params) 

    if @post.save 
     flash[:success] = "New Moment Posted" 
     redirect_to @post 
    else 
     flash[:danger] = @post.errors.full_messages.to_sentence 
     redirect_to root_url 
    end 
    end

post.rb

class Post < ActiveRecord::Base 
    include PublicActivity::Model 

    tracked owner: Proc.new {|controller, model| controller.current_user ? controller.current_user : nil }, 
      photo: proc {|controller, model| model.photo }, 
      body: proc {|controller, model| model.body }

請顯示您的'post_params'方法 – sjagr

我在更新的問題中包含了帖子參數。 –

我通過將自定義字段添加到活動表中解決了此問題。
