Probably easiest to check for values after calling super:
def initialize(values={})
super
raise ArgumentError unless some_criteria
# ...
end
Note that this approach makes little sense in Sequel. In Sequel, you can
do:
Model.new(values).save
but you can also do:
Model.new.set(values).save
So checking for values in initialize does not make sense. Sequel::Model
expects you to override validate and call super:
def validate
super
errors.add(:column1, "doesn't meet criteria") unless some_criteria
end
validate is called before saving the model.
There are numerous plugins that offer additional validation methods and
approaches.
Thanks,
