I'm importing a bunch of csv entries in my database with Laravel 4.
I can't really point at one column that has to be unique, it's a combination of 5 columns that makes it unique. However: how does one define this in Laravel?
Option 1: schema builder
You can use the $table->unique('email') method, but that only seems to allow one column, not a combination of columns.
Option 2: Validation
Less preferable, but I could validate the model before inserting it. However, again, using 'unique:[table]' validation rules, it will return an error when just one of the column values isn't unique, not a combination of them.
Can anyone tell me how I should go about this?
I'm sure I'm missing something, but I could use a push in the right direction :-)
Thanks,
Dieter
