ruby-on-rails - 如何使用私有(private)提交隐藏提要？

Question

在评估表单中有一个提交按钮和一个 <%= f.submit :private %>按钮。如果点击私有(private)提交，提交的信息将对查看个人资料的其他用户隐藏。

我们怎样才能同时使用 <%= f.submit :private %>隐藏提交的信息以防止在提要上显示？

activities/index.html.erb

<h1>Feed</h1>
<% @activities.each do |activity| %>
<% if current_user == @user %>
    <%= render_activity activity %>
  <% else %>
    <%= render_activity activity %> #We'd need to make .public_valuations work with this without getting an undefined method error.
  <% end %>
<% end %>

activities_controller.rb

class ActivitiesController < ApplicationController
  def index
    @activities = PublicActivity::Activity.order("created_at desc").where(owner_id: current_user.following_ids, owner_type: "User")
  end
end

为简洁起见，我将只包含 _create (还有 update 和 destroy )。每次用户提交估价时，它都会在提要上弹出，我们怎么能只做 public_valuations 显示？

public_activity/valuation/_create.html.erb

<% if activity.trackable %>
  <%= link_to activity.trackable.name, activity.trackable %></b>
<% else %>
  which has since been removed 
<% end %>

估值.rb

class Valuation < ActiveRecord::Base
  belongs_to :user
  acts_as_taggable
  validates :name, presence: true
  has_many :comments, as: :commentable
  include PublicActivity::Model
  tracked owner: ->(controller, model) { controller && controller.current_user }

    def public?
      private == true ? false : true
    end

  scope :randomize, -> do
      order('RANDOM()').
      take(1)
    end
end

用户 Controller

 def show
   if
     @valuations = @user.valuations
   else
     @valuations = @user.public_valuations
   end
 end

用户.rb

#gets public valutations or nil, if there's no public valutation
def public_valuations
  valuations.find(&:public?)
end

我从这个 railscasts 节目中获得了几乎所有的事件代码:http://railscasts.com/episodes/406-public-activity .

非常感谢您的宝贵时间!

由于我们无法通过 public_activity gem 解决这个问题，我从头开始创建了公共(public)事件，并试图在这里解决这个问题: How to make private activities?

失败的尝试

根据 Avdept 的建议:

class ActivitiesController < ApplicationController
    def index
      @activities = PublicActivity::Activity.not_private.order("created_at desc").where(owner_id: current_user.following_ids, owner_type: "User")
    end
end

在valuations.rb

def public? !private end => def public?; !private; end;
scope :not_private, -> { where(private: false) }

这给出:

SyntaxError in ActivitiesController#index (for line: def public? !private end => def public?; !private; end;)
/Users/galli01anthony/Desktop/Pecoce/app/models/valuation.rb:9: syntax error, unexpected '!', expecting ';' or '\n' def public? !private end => def public?; !private; end; ^ /Users/galli01anthony/Desktop/Pecoce/app/models/valuation.rb:9: syntax error, unexpected =>, expecting end-of-input def public? !private end => def public?; !private; end; ^
