mongodb - Doctrine2 Mongodb 添加更多 $or 运算符

Question

可以为教义2 ODM 创建以下查询吗？

db.Product.find({ "$or": [ { "name": new RegExp("test*", "i") }, { "tags": new RegExp("public true*", "i") } ], "$or": [{ "public": false, "_id": { "$in": [ ObjectId("4e74121c4fcfa9ff7ac90000"), ObjectId("4e74121c4fcfa9ff7ac80000") ] } }, { "public": true }] });

我不明白的教义2的主要问题是如何在$查询中添加加法$或？

这有助于我使用仍然缺少的 $and 运算符。

我目前正在使用 Symfony2 Doctrine2 Mongodb

Answer 1

/**
 * Adds an "or" expression to the current query.
 *
 * You can create the expression using the expr() method:
 *
 *     $qb = $this->createQueryBuilder('User');
 *     $qb
 *         ->addOr($qb->expr()->field('first_name')->equals('Kris'))
 *         ->addOr($qb->expr()->field('first_name')->equals('Chris'));
 *
 * @param array|QueryBuilder $expression
 * @return Builder
 */



/**
 * Adds an "and" expression to the current query.
 *
 * You can create the expression using the expr() method:
 *
 *     $qb = $this->createQueryBuilder('User');
 *     $qb
 *         ->addAnd($qb->expr()->field('first_name')->equals('Kris'))
 *         ->addAnd($qb->expr()->field('first_name')->equals('Chris'));
 *
 * @param array|QueryBuilder $expression
 * @return Query
 */

Answer 2

除了理论之外的一个小例子：

查询meta-language：

<condition1> AND (<field1 == value1> OR <field2 == value2>)

用 Doctrine 查询QueryBuilder：

$queryBuilder
    ->addAnd(<condition1>)
    ->addAnd(
        $queryBuilder
            ->expr()
            ->addOr(
                $queryBuilder
                    ->expr()
                    ->field('field1')
                    ->equals('value1')
            )->addOr(
                $queryBuilder
                    ->expr()
                    ->field('field2')
                    ->equals('value2')
            )
    );
