<tbody>
<% @departments.each do |d| %>
<% d.patients.each do |patient| %>
<tr>
<td><%= patient.patient_name %></td>
<td><%= d.name %></td>
<td><%= patient.consultant %></td>
<% end %>
<% end %>
</tbody>
<% @departments.each do |d| %>
<% d.patients.each do |patient| %>
<tr>
<td><%= patient.patient_name %></td>
<td><%= d.name %></td>
<td><%= patient.consultant %></td>
<% end %>
<% end %>
</tbody>
As shown in above code by using each loop in department I'm able to fetch department table's data in " <td><%= d.name %></td> ". Now I want to fetch same for consultant table i.e fetching consultant data in patient index file.
<tbody>
<% @departments.each do |d| %>
<% d.patients.each do |patient| %>
<tr>
<td><%= patient.patient_name %></td>
<td><%= d.name %></td>
<% @consultants.each do |c| %>
<td><%= c.name %></td>
<% end %>
</tr>
<% end %>
<% end %>
</tbody>
