Question

如何使用laravel 5.2架构生成器创建唯一约束？

Schema::create('my_pivot', function(Blueprint $table){ 

    $table->increments('id'); 
    $table->integer('table1_id')->unsigned(); 
    $table->integer('table2_id')->unsigned(); 

    $table->foreign('table1_id')->references('id')->on('table1'); 
    $table->foreign('table2_id')->references('id')->on('table2'); 

    //Here i need to add an unique constraint to 'key1' + 'key2' 

}); 

Answer 1

您可以将数组传递给unique方法。

$table->unique(['key1', 'key2']);
