Need help. RuboCop tests are failing because of Cyclomatic and Perceived complexity for reify is too high. Don't know how to fix it. |

to_sym isn't necessary here -- send automatically does that for you

I think the "send" method in ruby v1.9.3 accepts only a symbol.
I'm sure we can find a way to extract a private method. (http://refactoring.com/catalog/extractMethod.html) |
This should help: #734 Oh!, I see you're also working on that? |
Haha, we came up with the same thing :D |

@jaredbeck Refactored the "reify_associations" method to return the model, so that in future we can use it in any other place if required. |

Is there a test that covers this line? It seems like the reference to collection here would raise a NameError. What am I missing?

Nice catch. But I don't think this condition is ever met as the base model is always created before the associated model. Ex:- Widget instance is created before the wotsit instance.
There is a case when this condition is met, i.e when a new widget is created and the association is changed to point to the new widget.
In this case we should not destroy the widget instance as widget instance is not dependent on the wotsit instance.
I have written tests which covers the above case.

I think I'd rather keep the explicit return value here, instead of moving it to reify_associations.

So you can call @project.versions.last.reify( belongs_to: true) and get the client model at the time of last change of the project model.
