Problem with blanks and nils with unique indexes

[justin808]

rails_admin is creating new records with "" (empty string) rather than nil, and for a column where there is a unique index, allowing for nil, then this leads to a non-unique index violation, as the second record with a "" is reported as not unique.

There could be a suggestion to use a gem like strip_attributes or auto_strip_attributes, and configure at models to strip the attributes that can be null. For me this solution worked fine . =D @justin808
But of course i had to check all attributes.
