接收未知属性错误公共活动Rails 4

我目前正在使用Public_Activity进行用户通知。问题在于，如果没有Public :: Activity导致500内部服务器错误，我无法创建新帖子。该错误是在我的创造方法发生了Posts_Controller.rb接收未知属性错误公共活动Rails 4

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 } 

    default_scope -> { order(created_at: :desc) } 

    validates :body, presence: true, length: {maximum: 150} 
    validates :photo, presence: true #CarrierWave 

    mount_uploader :photo, PhotoUploader 

    has_many :comments, as: :commentable, dependent: :destroy 
    acts_as_commentable 
    belongs_to :user 
end 

Cannot render console with content type multipart/form-dataAllowed content types: [#<Mime::Type:0x3b50128 @synonyms=["application/xhtml+xml"], @symbol=:html, @string="text/html">, #<Mime::Type:0x3b4b610 @synonyms=[], @symbol=:text, @string="text/plain">, #<Mime::Type:0x3b430d8 @synonyms=[], @symbol=:url_encoded_form, @string="application/x-www-form-urlencoded">]

Posts_Controller.rb参数活动

def post_params 
    params.require(:post).permit(:body, :photo, :video) 
end

放映视图

<div class="col-sm-3"> 
    <ul class="list-group"> 
    <% @activities.each do |activity| %> 
     <li class="list-group-item">

请显示您的'post_params'方法 – sjagr

我在更新的问题中包含了帖子参数。 –

我通过将自定义字段添加到活动表中解决了此问题。
