Sounds like a good chance to pull that functionality out into a function
for reuse:
class Array
def all_elements_are?(klass)
self.inject(true) { |same, n| same && n.instance_of?(klass) }
end
end
a = ['foo', 'bar', 'baz']
a.all_elements_are?(String) #=> true
b = ['foo', 5, 'baz']
b.all_elements_are?(String) #=> false

anyone know of a better way to make sure all items in an array are
instances of the same class? specifically i want to make sure they're
all instances of the same AR class.
This just doesn't seem the best way:
def method
object_class = array.first.class
array.each do | record |
raise ArgumentError unless record.class == object_class
end
end
