Hi,
I've got a question regarding my models in my Rails app. Let's say I
have an object:
User
which has_many:
Thing1
and Thing1 has_many:
Thing2
and Thing2 has_one:
Thing3
When I go to display this in my template, like this:
<table border="1">
<tr>
<th>Title</th>
<th>Date</th>
<th>Event</th>
</tr>
<% @user.thing1.each do |c| %>
<tr>
<td><%=h c.title %></td>
<td><%=h c.date %></td>
<td>
<table>
<tr>
<th>Thing2</th>
</tr>
<% c.thing2.each do |be| %>
<tr>
<td>
<%=h be.workout_type %></td>
<%=h be.thing3.name %>
</td>
</tr>
<% end %>
</table>
</td>
</tr>
<% end %>
I get:
undefined method `name' for nil:NilClass
I'm assuming this means there is no Thing3 object for this particular
Thing2 object.
I just bought Agile Development with Rails and am starting to go
through that...it's surely noob question but can someone set me
straight?
Thanks!
Jon
