# There is a bug in Rails which causes issues when using accepts_nested_attrs
# and inverse_of on associations:  https://github.com/rails/rails/issues/7809/
# This code was lifted from the pull request of the bug shown above.  It solves
# the issue.  Until this is merged into rails we will have to carry the patch
# ourselves.
