Using rails-generated code in "show"

Rails
1

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 %>

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

<% if column.null == "true"  %>

<% else %>

<%=h @ward.send(column.name) %>

<% end %>

<% 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!!

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
