Doctrine 2中的简单索引定义

Question

Is there a simple way to define a non-unique index over a column?

When I define unique index, this is perfectly sufficient:

/** @ORM\Entity */
class Foo {
    /** @ORM\Column(type="string", unique=true) */
    private $foo;
}

However, for non-unique index, I need this bunch of boilerplate:

/**
 * @ORM\Entity
 * @ORM\Table(indexes={@Index(name="foo_idx", columns={"foo"})})
 */
class Foo
{
    /** @ORM\Column(type="string") */
    private $foo;
}

I'd prefer something like @ORM\\Index annotation on the single property, or index=true etc...

I have to disappoint you...

@ORM\Table(indexes={@Index(name="foo_idx", columns={"foo"})})

is as simple as the annotation can get.

If $foo would be a relating entity it would be indexed automatically, but for indexing fields you need to add the index as you did.

You can find all @Column attributes here in the Doctrine 2 documentation . Sadly enough index is not among them.

Maybe you can make a feature request here on GitHub .
