Q: 如何在laravel migrations中設定兩個欄位組合為unique

A: 使用陣列把兩個欄位包起來傳進去

The second param is to manually set the name of the unique index. Use an array as the first param to create a unique key across multiple columns.

 

$table->unique(array('mytext', 'user_id'));

 

or (a little neater)

 

$table->unique(['mytext', 'user_id']);
