Merge tables to a single table - html

Question

Relevant snippets
Show.html.erb
<% outbound_messages.each do |outbound_message| %>
<h5>Outbound Message</h5>
<%= render "trace/display_tabular_data", :data => outbound_message %>
<% end %>
Display_tabular_data.html.erb
<table border="1px solid black">
<thead>
<tr>
<%data.each do |key,value|%>
<th><%=key.capitalize%></th>
<%end%>
</tr></thead><tr>
<%data.each do |key,value|%>
<td><%=value%></td>
<%end%>
</tr>
</table>
So what happens is that each row of data, gets printed in a unique table.
So one has something like http://imgur.com/1gskRvX
But clearly a much better result would be as a single table (Desired outcome)
Outbound Message
Message ID, Exchange, Relayed
Row1
Row2
Row3
Row4
...
....
Any ideas how I can go about this? Display_tabular_data is called at-least 15 times in different places in show.html.erb, so it would be much easier if it was somehow possible to get this final result by making changes only in display_tabular_data, and not in show.html.erb. If not possible, please give me the best possible way?

Answer 1

If you don't want to render a separate table for every object, how about something like this in show.html.erb:
<% unless outbound_messages.empty? %>
<%= render 'trace/display_tabular_data', :data => outbound_messages %>
<% end %>
And then in the partial:
<h5>Outbound Messages</h5>
<table border="1px solid black">
<thead>
<tr>
<% data.first.each do |key,value| %>
<th><%=key.capitalize%></th>
<% end %>
</tr>
</thead>
<% data.each do |outbound_message| %>
<tr>
<% outbound_message.each do |key,value|%>
<td><%=value%></td>
<% end %>
</tr>
</table>
This only works if you are confident that every outbound_message has the same set of keys.

Answer 2

Here you go..
<% if outbound_messages.count > 0 %>
<h5>Outbound Message</h5>
<table border="1px solid black">
<thead>
<tr>
<td>Message ID</td>
<td>Exchange</td>
<td>Relayed</td>
</tr>
</thead>
<% outbound_messages.each do |outbound_message| %>
<tr>
<td>
<%= outbound_message[:message_id] %>
</td>
<td>
<%= outbound_message[:exchange] %>
</td>
<td>
<%= outbound_message[:relayed] %>
</td>
</tr>
<% end %>
</table>
<% end %>
You can eliminate the partial entirely
