Question

I have a web page where some information are asked. But some value can be blank. But if I save more than once my formulary with some blank value if says that Value has been already taken. This is normal since I used: validates_uniqueness_of

My question is: if I save value as nil, does this problem will be solved ?? If yes how save value as nil. Or what are others solutions please ??

Thanks in advance.

Answer 1

It’s in the docs.

validates_uniqueness_of :my_value, :allow_blank => true
