I need a hint on what could be causing the following error message:

NameError in Project areasController#destroy  
uninitialized constant ProjectArea::KeyAspect  
D:/Ruby/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active\_support/dependencies.rb:477:in  
`const_missing’ (eval):1:in`configure\_dependency\_for\_has\_many’  
#{RAILS\_ROOT}/app/controllers/project\_areas\_controller.rb:129:in  
`destroy’ script\server:3 -e:2:in`load’  
-e:2

Many thanks people

There’s not enough information here. I’d say it probably lies in the  
ProjectArea model. My guess would be that you have a has\_many  
association that looks like this:

has\_many :KeyAspects

instead of

has\_many :key\_aspects?
