Models and query sets should provide a #get_or_create method allowing to do a record lookup based on one or more field predicates and, if the lookup returns zero results, create the corresponding record.
For example:
Tag.get_or_create(label: "crystal")
It should be noted that this method should allow to specify "default' field values when creating the new record if it is not found.
An alternative #get_or_create! method should also be provided, but contrary to #get_or_create, this one should raise when creating the new record if it is invalid.
