Using rails-generated code in "show"

Hi!

I used scaffold to create my mvc for my table. I have only written one other ROR application, and since I was winging it, I didn't take advantage of the rails-generate code.

My scenario is:

User clicks save on form, and is redirected to the "show" view where they see what they just saved. Code is this:

<% session[:ward_id] = @ward %> <p>

<% for column in Ward.content_columns %>   <b><%= column.human_name %>:</b>

    <% if column.null == "true" %>

    <% else %>

    <%=h @ward.send(column.name) %>

<% end %>

</p> <% end %>

My error is that beloved "you have a nil object when you didn't expect it!" I am trying to check for nil values and have it just display nothing but the human_name when it hits a nil. I have tried many different combinations and can't seem to get it right. Any direction or suggestion is always appreciated!!

Thank you!! ~~Ali

Probably you don't pass the id parameter to the 'show' controller

You have to do something like this after the creation of the object:

redirect_to :action => 'show', :id => myobject.id
