Question

未过滤仅由用户的关注添加的评论。我得到了所有的评论。大约有 11 条评论，只有 8 条是由用户的关注添加的，我想要 8 条但得到 11 条。 如果我从包含的模型中删除 required 我得到所有结果 cuz 然后内部查询被删除，但如果我保留它们，我会得到如下所述的错误：

你能想到我做错了什么吗？提前致谢。

我只是使用了以下参数来修复它。

let queryParameters = {
    distinct: true,
    include: [{
        duplicating: false,
        required: true,
        model: User,
        attributes: ['userId','active'],
        include: [{
            model: User,
            attributes: ['userId','active'],
            as: 'UserFollower',
            through: {
                where: { followingUserId: userId },
            },
            duplicating: false,
            required: true,

        }]
    }],
    offset: offsetValue,
    limit: limitValue
};

幸运的是它正在工作。我得到了正确的查询。 选择“RestaurantReview”。“review_id”作为“reviewId”，“RestaurantReview”。“review”，“RestaurantReview”。“user_id”作为“userId”，“RestaurantReview”。“restaurant_id”作为“restaurantId”，“RestaurantReview”。评级”，“RestaurantReview”。“已批准”，“RestaurantReview”。“滥用”，“RestaurantReview”。“createdAt”，“RestaurantReview”。“updatedAt”，“RestaurantReview”。“deletedAt”，“用户”。“user_id” AS "User.userId", "User"."active" AS "User.active", "User->UserFollower"."user_id" AS "User.UserFollower.userId", "User->UserFollower"."active" AS "User.UserFollower.active", "User->UserFollower->Follower"."following_user_id" AS "User.UserFollower.Follower.followingUserId", "User->UserFollower->Follower"."followed_user_id" AS "User. UserFollower.Follower.followedUserId", "User->UserFollower->Follower"."createdAt" AS "User.UserFollower.Follower.createdAt", "User->UserFollower->Follower"."updatedAt" AS "User.UserFollower. Follower.updatedAt" FROM "restaurant_review" AS "RestaurantReview" INNER JOIN "users" AS "User" ON "RestaurantReview"."user_id" = "User"."user_id" AND ("User"."deletedAt" > '2019-07-08 07:08:00.264 +00:00' OR "User"."deletedAt" IS NULL) INNER JOIN ( "follower" AS "User->UserFollower->Follower" INNER JOIN "users" AS "User->UserFollower" ON "User->UserFollower"."user_id" = "User->UserFollower->追随者”。“followed_user_id”和“用户->用户追随者->追随者”。“following_user_id”= 4）ON“用户”。“user_id”=“用户->用户追随者->追随者”。“following_user_id”和（“用户- >UserFollower"."deletedAt" > '2019-07-08 07:08:00.264 +00:00' 或 "User->UserFollower"."deletedAt" 为 NULL) WHERE ("RestaurantReview"."deletedAt" > '2019 -07-08 07:08:00.264 +00:00' OR "RestaurantReview"."deletedAt" IS NULL)
