If I understood what you're looking for, this should be it. I don't watch in the database but just in the model for the presence of the fields you want to show, I hope is enough... Here is the line to put before the loop, this is the one for the id.

<%%= 'Id: ' + @<%= singular_table_name %>.id.to_s unless @<%= singular_table_name %>.methods.index(:id).nil? %>

moreover I could say that there is for sure a better way to check the presence of the field instead of using the index function, and probably a better way overall, but this works.

You have doubly wrapped in asp style tags:

Id: <%= object.id %>
Created at: <%= object.created_at %>
Updated at: <%= object.updated_at %>

That code should show the 3 columns as you desired, or they don't exist, see if they're in the database table.

  • use doubly wrapped because i didn't want to it executed,it's a scaffold template(build template for template) – mlzboy Nov 02 '10 at 08:59
