Loop through array in an ERB template

Q: Loop through our statuses array in an ERB template. Assume we have statuses set up as an array and want to print out the name.

I am not quite sure what it is they are asking of me here.

<% @statuses.each do |status| %>
Name: <br />
<% end %>

I got the answer correct, but I just don't understand it.

<% @statuses.each do |status| %>
Name: <br />
<tr>
   <td><%= status.name %></td>
</td>
<% end %>

So given the correct answer code you ran the HTML output would look as follows:

Name: 
Joe Name: 
Stan Name: 
Gus

The reason this is happening, is that you first have "Name:" which is followed by a line break which pushes the code to the next line.

To pass the quiz you only need to add the <%= status.name %> before the break tag.

<% @statuses.each do |status| %>
Name: <%= status.name %><br />
<% end %>

Which produces the following view:

Name: Joe 
Name: Stan
Name: Gus

If you wanted to structure the data in a table as Jim did in the video and achieve the same view as directly above you could do the following:

<table>
<% @statuses.each do |status| %>
  <tr>
    <td>Name:</td>
    <td><%= status.name %></td>
  </tr>
<% end %>
</table>
