Question

Im trying to figure out how to have data from multiple models show up on the same calendar in my view. Right now it’s showing birthdays, but i would love to add anniversaries & holidays as well (which are currently just lists in view).. *stripped unnecessary formatting for clarity

 <% if @user.friends.any? %>
    <h3>Upcoming Birthdays</h3>
    <div id="calendar">
        <h2 id="month">
         <%= link_to "<", :month => (@date.beginning_of_month-1).strftime("%Y-%m") %>
         <%=h @date.strftime("%B %Y") %>
         <%= link_to ">", :month => (@date.end_of_month+1).strftime("%Y-%m") %>
        </h2>
                    <%= calendar_for @friends, :year => @date.year, :month => @date.month do |calendar| %>
                     <%= calendar.head('mon', 'tue', 'wed', 'thu', 'fri', 'sat', 'sun') %>
                      <%= calendar.day(:day_method => :dob) do |date, friends| %>
                       <%= date.day %>
                        <ul>
                            <% friends.each do |friend| %>
                            <li> <%= link_to h(friend.name), friends %><%= "\'s birthday"%></li>
                         <% end %>
                        </ul>
                    <% end %>
                <% end %>
    </div>
    <% end %>

    <% if @user.holidays.any? %>
    <h3>Upcoming Holidays</h3>
    <% @user.holidays.each do |hld| %>
      <td><%= hld.name %></td>
      <td><%= hld.date %></td>
    <% end %>
    </tbody>

Models

class User < ActiveRecord::Base
  has_many :friends
  has_many :user_holidays
  has_many :holidays, :through => :user_holidays
  has_many :anniversaries



class Holiday < ActiveRecord::Base
  attr_accessible :name, :date

  has_many :users, :through => :user_holidays

end

  attr_accessible :holiday_id, :user_id
  belongs_to :user
  belongs_to :holiday

class Anniversary < ActiveRecord::Base
  belongs_to :user

There’s nothing about a view that keeps it from using data from other models. You just have to make sure that the controller action passes it to the view somehow. You’re currently passing one @date object and one @user object; if you want other objects you should set those as well. I advise you to make those objects accessible via the @user object, which is to say that you should create instance methods for a User so that you can access them in a view

class User

  def birthdays
    ...
  end

  def anniversaries
    ...
  end

  def holidays
    ...
  end
end

And then in your view, you can simply call @user.birthdays etc, etc.
