Question

This is my Action model:

class Action < ActiveRecord::Base end  class Fold < Action end  class Check < Action end  class Call < Action end  class Bet < Action end 

In another model, I have this

class Deal < ActiveRecord::Base   def Deal.parse_action(action_string)     case action_string     when 'folds':   Fold.new()     when 'checks':  Check.new()     when 'calls':   Call.new()     when 'bets':    Bet.new()     when 'raises':  Bet.new()     else nil        end   end   # ... end 

Now, when I test this if this works in my unit tests, everything appears to work. But as soon as I start the web server in development mode, I get this:

 NameError (uninitialized constant Deal::Fold):   app/models/deal.rb:115:in `parse_action'   ... 

Why does it think Fold exists within the namespace Deal? And why does this not happen in the test environment?

Answer 1

I don’t use Rails at work, but I sometimes come across the scenario of a class being known when I’m running tests, but not when I’m running the executable. That happens because I have the requisite ‘require’ statements in my test files for the relevant files, but I hadn’t got around to putting the requisite ‘require’ statements in production code.
