Transient Attributes with Fabrication Tweet

While writing a cucumber feature last week I found myself needing to assert on the count of a given associated model. The feature looked a bit like this (domain has been changed for clarity):

Unfortunately, we do not have the ability to tell the fabricator how many authors we'll need directly on the model, so the above feature won't work.

To get it to work we can head on into the fabricator file for Article. We'll use transient_attributes to hold our authors_count temporarily, then we'll use an before create to ensure the proper number of authors.

And there we go.

A few small notes

The step Given the following articles with authors is a Fabrication step.
To generate these run rails generate fabrication:cucumber_steps which creates several step definitions for interacting with fabricators.

Thanks for reading. So sorry I've brought another blog example into this world. Forgive me.
