model for simplicity, but these matchers will work just as well using an
ActiveModel model.

**IMPORTANT NOTE!** This matcher works differently from other validation
matchers. Since the very concept of uniqueness depends on checking against a
pre-existing record in the database, this matcher will first use the model
you're testing to query for such a record, and if it can't find an existing one,
it will create one itself. Sometimes this step fails, especially if you have
other validations on the attribute you're testing (or, if you have
database-level restrictions on any attributes). In this case, the solution is to
create a record before you use `validate_uniqueness_of`.
