I am working through Tutorial 16 in "Rapid Rails with Hobo."
Everything is fine until I put the following code in /views/countries/
show.dryml which I copied directly from the book. Deleting the
show.dryml file does away with the error.
<show-page>
<content-body:>
<a action="edit">Edit My Country</a><br/>
</content-body:>
</show-page
When I click on the "Countries" tab and then click on a country I get
a page of error messages which begin as below. Any help appreciated.
Hobo::Dryml::DrymlSyntaxError in Countries#show
Showing app/views/countries/show.dryml where line # raised:
File: app/views/countries/show.dryml
#<REXML::ParseException: #<NoMethodError: You have a nil object when

You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]>
