问题描述

我正在使用 Laravel 4 在我的数据库中导入一堆 csv 条目.

I'm importing a bunch of csv entries in my database with Laravel 4.

我不能真正指出必须是唯一的一列,它是 5 列的组合,使其独一无二.但是:如何在 Laravel 中定义这一点?

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?

选项 1:架构构建器
您可以使用 $table->unique('email') 方法,但这似乎只允许一列,而不是列的组合.

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.

选项 2:验证
不太可取,但我可以在插入模型之前对其进行验证.但是,再次使用 'unique:[table]' 验证规则,当只有一个列值不是唯一的而不是它们的组合时,它将返回错误.

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.

谁能告诉我该怎么做?
我确定我错过了一些东西,但我可以朝正确的方向推动:-)

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 :-)

推荐答案

可以组合:

$table->unique( array('email','name') );

几乎所有 Laravel 中的东西都可以接受数组来做任何你需要做的事情.

And pretty much everything in Laravel will accept arrays to do whatever you need to with 'more than one'.
