用户表格包含

  t.boolean :admin,              :default => false
  t.string :email,              :null => false, :default => ""
  t.string :department
  t.string :username

  t.string :encrypted_password, :null => false, :default => ""

my question is how do i display or notify the admin that today is a user s birthday i would love if there could be a model,controller and the view inclusive in the answer thanks

Ok 您已经拥有了模型, 即用户。我只是要添加一个方法, 告诉我们用户的生日是今天还是今天 :

class User
  def birthday_today?
    birthday == Date.today?
  end
end

然后在控制器中,让我们在控制器中表示您想要在索引页面上显示此选项。我将假设您有您自己的认证解决方案, 因此让我们对当前(_user) 的呼叫将会让用户使用现在登录的用户

class WelcomeController < ApplicationController
  def index
    @display_honourees = current_user.admin?
    @honourees = User.all.find_all {|u| u.birthday_today? }
  end
end

在那里,我们拥有我们所需要的所有数据。现在让我们展示它们:

<html>
  ...
  <% if @display_honourees %>
    <ul>
      <% @honourees.each do |honouree| %>
        <li>It s <%= honouree.username %> s birthday today! Make a party!</li>
      <% end %>
    </ul>
  <% end %>
  ...
</html>

这是你需要的吗?
