Re: validates_uniqueness_of question
Hi All,
I am trying write a validation rule where I need to ensure that when a
certain value is updated or created in a particular columns, a number of
other columns columns are unique and that another column does not contain a
certain value.
I have been able to use the validates_uniqueness_of :column_a (to be
updated or inserted) with , :scope =>
[ :column_b , :column_c , :column_d ]
