Multiple columns unique combination validation

[louiemej]

I would like to request validation for unique of combination certain columns for create and update

example: firstname, middlename, lastname and suffixname (generational suffixes) should be unique
firstname => required | unique with middlename, lastname and suffixname,
middlename => not required | unique with firstname, lastname and suffixname
lastname => required | unique with firstname, middlename and suffixname
suffixname => not required | unique with firstname, middlename and lastname

May be a keyword like 'uniqueWith: [table1.column1, table1.column2]' is good.

And adding unique combination with other table is great
'uniqueWith: [table1.column1, table1.column2, table2.column1, table2.column2]'

And adding unique combination with other database is also great
'uniqueWith: [db1.table1.column1, db2.table1.column1, db3.table2.column1, db4.table2.column1]'

This is just my ideas and I love to see it in Adonisjs
