def message
  Shoulda::Matchers.word_wrap "The \#{matcher_name} matcher attempted to set :\#{attribute_name} on\n\#{model.name} to \#{value_written.inspect}, but when the attribute was\nread back, it had stored \#{value_read.inspect} instead.\n\nThis creates a problem because it means that the model is behaving in a\nway that is interfering with the test -- there's a mismatch between the\ntest that you wrote and test that we actually ran.\n\nThere are a couple of reasons why this could be happening:\n\n* ActiveRecord is typecasting the incoming value.\n* The writer method for :\#{attribute_name} has been overridden so that\n  incoming values are changed in some way.\n\nIf this exception makes sense to you and you wish to bypass it, try\nadding the `ignoring_interference_by_writer` qualifier onto the end of\nyour matcher. If the test still does not pass after that, then you may\nneed to do something different.\n\nIf you need help, feel free to ask a question on the shoulda-matchers\nissues list:\n\nhttps://github.com/thoughtbot/shoulda-matchers/issues\n  MESSAGE\nend\n"
