如何将自动增量设置为非主键? [英] How to set auto increment into non primary key?

问题描述

如何设置不是自动创建方法主键的数据库自动增量字段?

How would I set a database auto increment field that is not a primary key on the creation method?

唯一的方法是使用原始查询?

The only way is using a raw query?

DB::statement('ALTER TABLE table CHANGE field field INT(10)AUTO_INCREMENT');

推荐答案

尚未实现.但是，我在

It is not implemented to do so. However, I found this over at the Laravel Forums:

Schema::table('table', function(Blueprint $t) {
    // Add the Auto-Increment column
    $t->increments("some_column");

    // Remove the primary key
    $t->dropPrimary("table_some_column_primary");

    // Set the actual primary key
    $t->primary(array("id"));
});

这未经测试，但可以正常工作.我不确定Laravel如何调用其主键，也许您必须先检查一下并改写dropPrimary()行才能使其正常工作.

This is not tested but should work. I am not sure about how Laravel calls their primary keys, maybe you have to check that first and adapt the dropPrimary() line in order to make it work.
