在评估表中有一个提交按钮和一个<%= f.submit :private %>按钮。如果单击私人提交，提交的信息将对查看个人资料的其他用户隐藏。

我们如何还可以<%= f.submit :private %>用来隐藏提交的信息，使其不显示在提要上？

活动/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 %>

活动控制器.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，我将只包括_create（还有updateand destroy）。每次用户提交估价时，它都会在提要中弹出，我们如何才能只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

users_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 剧集中获得了几乎所有的活动代码：http ://railscasts.com/episodes/406-public-activity 。

这就是我们如何使个人资料的私人提交工作： 如何使用私人提交来隐藏个人资料？

非常感谢您的参与！

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活动，并试图在这里解决这个问题： 如何进行私人活动？

失败的尝试

在 Avdept 的建议下：

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

在估值.rb

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

这给出了：

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; ^
