It sounds like you want to make sure that code that does this:
@foo.bars
would raise a NoMethodFound exception? If so, you can just reopen the
class:
class Foo
def bars
raise NoMethodError.new("undefined method 'bars'")
end
end
Then,
@foo.bars # => raises exception
However, this isn't really removing all of remnants of the
association, so again it depends on what constitutes "removed enough"
for your situation.
