Overrides in Camping
If you want to add a call to all the controllers in your Camping miroframework app you can use before or after overrides. These are similar to the before_filter in Rails.
Remember to return the superclass or Camping will throw a “Read error: #<NoMethodError: undefined method `status’ for nil:NilClass>” because it can’t call back into the returned controller. A modification of the above linked wiki page example illustrates -
Camping.goes :YourApp
module YourSession
def service(*a)
@session = YourApp::Session.new
s = super(*a)
@session.close
#return s from above after completing
s
end
end
module YourApp
include YourSession
end
