Hi - I want to allow duplicate fields values if the field is blank,
but disallow duplicates if it’s not. Is there a
validates_uniqueness_of_if_present equivalent?
Thanks,
Dino

You can use :allow_nil or :allow_blank attributes to it like
validates_uniqueness_of :email, :allow_nil => true
this would skip the validation if field is nil.
:allow_blank works same way on empty strings.
And then all/most validations com with the :if and :unless options
that would allow for more detailed determination if the validation
should be used

Hi,
As you required to place duplicate value if field is blank than you
just use
validates_uniqueness_of :field_name,:allow_blank => ‘true’
:allow_nil - If set to true, skips this validation if the attribute
is nil (default is false).
:allow_blank - If set to true, skips this validation if the attribute
is blank (default is false).
