我目前正在使用 Public_Activity 进行用户通知。问题是如果没有 Public::Activity 导致 500 内部服务器错误,我无法创建新帖子。该错误发生在我的Posts_Controller.rb的创建方法中
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 }
