I want to show data from two tables in a single view - ruby-on-rails

Question

I have two tables: one named um_org_data and the other addresses.
The problem is that I want to show the data from um_org_data with addresses where addresses has a foreign key um_org_datum_id.
Here is the code of my view in which I want to show the data from two tables together:
<p id="notice"><%= notice %></p>
<div class="container">
<div class="row">
<div class="span3 pull-right">
<div class="well">
<h2>Heading</h2>
<p>Sample text</p>
</div>
</div>
<div class="span9">
<h2>Organization Details</h2>
<table class="table table-hover">
<tr>
<th col span="1" style="width: 200px">
</i> Organization Name:
</th>
<td><%= #um_org_datum.org_name %></td>
</tr>
<tr>
<th col span="1" style="width: 250px">
</i> Organization Description:
</th>
<td><%= #um_org_datum.org_description %></td>
</tr>
<tr>
<th col span="1" style="width: 250px">
</i> Web Domain:
</th>
<td><%= #um_org_datum.webdomain %></td>
</tr>
<tr>
<th col span="1" style="width: 200px">
<%= fields_for :address_attributes do |p| %>
<%= p.label 'Office Address' %><br />
</th>
<td><%= p.address.offc_addr %></td>
<% end %>
</tr>
<tr>
<th col span="1" style="width: 200px">
</i> Office Phone Number:
</th>
<td><%= #um_org_datum.offc_ph %></td>
</tr>
</table>
<div class="control-group">
<div class="controls">
<a class="btn" href="/um_org_data" style="text-color:black">View all</a>
</div>
</div>
</div>
</div>
</div>
I don't use any join query in the controller as I don't know how to use join query. If this problem needs a join query, please tell me what is the syntax and what I have to change in the view form to show attributes of both tables.
table name: um_org_data , attributes: id, oeg_name, org_description, webdomain
table name: adrresses , attributes: id, offc_addr, um_org_datum_id
Thanks in advance!

Answer 1

Do you have 1:n association? Am I right?
Definitely remove the fields_for...you are not in a form!
Change this:
<tr>
<th col span="1" style="width: 200px">
<%= fields_for :address_attributes do |p| %>
<%= p.label 'Office Address' %><br />
</th>
<td><%= p.address.offc_addr %></td>
<% end %>
</tr>
to this:
<tr>
<th col span="1" style="width: 200px">Office Address</th>
<%= #um_org_datum.addresses.each do |p| %>
<td><%= p.office_addr %></td>
<% end %>
</tr>
Check out the markup, but the logic should be clear now..

Answer 2

I'm assuming you have the following in your models
um_org_datum
has_many :addresses
address
belongs_to :um_org_datum
Does this work?
<tr>
<th col span="1" style="width: 200px">Office Address</th>
<%= #um_org_datum.addresses.each do |p| %>
<td><%= p.offc_addr %></td>
<% end %>
</tr>
