allow_blank => false can be ineffective on validates_length_of

Reported by Jacob Williams | October 25th, 2010 @ 05:49 PM


I expected

    validates_length_of :foo, :maximum => 10, :allow_blank => false

to prohibit empty strings, but it doesn't. If this is the desired behavior it would be helpful for the docs to make it clear (for instance, "Note: setting :allow_blank to false will not cause this validation to fail if it would otherwise pass.")

    • State changed from “new” to “wontfix”
    • Importance changed from “” to “Low”

    The documentation explicitly states that the validation will be skipped if the value is blank so it follows that the validation will not be skipped if the value is not blank. Feel free to check out the docrails project if you think the documentation could be improved.
