# The option currenlty held by the object will be selected, provided that the object is available.
#
# This can be used to provide a default set of options in the standard way: before rendering the create form, a
# new model instance is assigned the default options and bound to @model_name. Usually this model is not saved
# to the database. Instead, a second model object is created when the create request is received.
# This allows the user to submit a form page more than once with the expected results of creating multiple records.
# In addition, this allows a single partial to be used to generate form inputs for both edit and create forms.
