Question

未过滤评论，仅由用户关注添加。我得到所有评论。大约有11条评论，而只有8条被用户关注添加，我想要8条但得到11条。如果从包含的模型中删除了必需的，则会得到所有结果，因为内部查询将被删除，但是如果保留它们，则会得到如下所述的错误：

// user model
const User = sequelize.define('User', {
    userId: {
        type: DataTypes.INTEGER,
        primaryKey: true,
        autoIncrement: true,
        field: 'user_id'
    },
    active: {
        type: DataTypes.INTEGER,
        defaultValue: 1
    },
}, {
    tableName: 'users',
    timestamps: true,
    paranoid: true
});

//Associations
User.associate = function(models) {
    models.User.belongsToMany(models.User, {
        through: 'Follower',
        foreignKey: 'followingUserId',
        otherKey: 'followedUserId',
        as: 'UserFollower'
    });
};

// follower model
const Follower = sequelize.define('Follower', {
    followingUserId: {

        allowNull: false,
        field: 'following_user_id'
    },

        allowNull: false,
        field: 'followed_user_id'
    }
}, {
    tableName: 'follower'
});

// review model
const RestaurantReview = sequelize.define('RestaurantReview', {
    reviewId: {
        type: DataTypes.INTEGER,
        allowNull: false,
        primaryKey: true,

});

//Query I am firing is :

            }
        }]
    }],
    offset: offsetValue,
    limit: limitValue
};
// END All the query parameters

const reviewsObject = await reviewModel.findAndCountAll( queryParameters );

//我得到的查询是：

有11条评论，而只有8条是由用户关注添加的，我希望有8条，但得到11条。

错误：

您能想到我做错了什么吗？预先感谢。

我只是使用以下参数对其进行了修复。

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“ AS” reviewId“，” RestaurantReview“。”评论“，” RestaurantReview“。” user_id“ AS” userId“，” RestaurantReview“。” restaurant_id“ AS” restaurantId“，” RestaurantReview“。评级”，“ RestaurantReview”，“已批准”，“ RestaurantReview”，“已滥用”，“ RestaurantReview”，“ createdAt”，“ RestaurantReview”，“ updatedAt”，“ RestaurantReview”，“ deletedAt”，“ User”和“ user_id” AS“ User.userId”，“ User”。“活动” AS“ User.active”，“ User-> UserFollower”。“ user_id” AS“ User.UserFollower.userId”，“ User-> UserFollower”。“活动” AS“ User.UserFollower.active”，“ User-> UserFollower-> Follower”。“ following_user_id” AS“ User.UserFollower.Follower.followingUserId”，“ User-> UserFollower-> Follower”。“ followed_user_id” AS“用户。 UserFollower.Follower.followedUserId“，” User-> UserFollower-> Follower“。” createdAt“ AS” User.UserFollower.Follower.createdAt“，” User-> UserFollower-> Follower“。” updatedAt“ AS” User.UserFollower。“ Follower.updatedAt”来自“ restaurant_review”，如“ RestaurantReview”，INNER JOIN，“用户”，如“用户” ON“ RestaurantReview”。“ user_id” =“用户”。“ user_id” AND（“用户”。“ deletedAt”>'2019-07-08 07：08：00.264 +00：00'或“用户”。“ deletedAt” IS NULL）INNER JOIN（“跟随者” AS“ User-> UserFollower-> Follower” INNER JOIN“ users”作为“ User-> UserFollower” ON“ User-> UserFollower”。“ user_id” =“ User-> UserFollower->关注者”。“ followed_user_id” AND“ User-> UserFollower-> Follower”。“ following_user_id” = 4）ON“ User”。“ user_id” =“ User-> UserFollower-> Follower”。“ following_user_id” AND（“ User- > UserFollower“。” deletedAt“>'2019-07-08 07：08：00.264 +00：00'或” User-> UserFollower“。” deletedAt“ IS NULL）WHERE（” RestaurantReview“。” deletedAt“>'2019 -07-08 07：08：00.264 +00：00'或“ RestaurantReview”。“ deletedAt”为NULL）

嵌套包含在参考关系上无法正常工作
