Node.js 如何使用子表中的数据在Sequelize中查找数据

node.js sequelize.js

Node.js 如何使用子表中的数据在Sequelize中查找数据,node.js,sequelize.js,Node.js,Sequelize.js,因此，我使用Sequelize创建了这个查询，以便在数据库中查找配置文件，但我希望能够使用存储在不同（子）表/模型中的条件查找结果，而不仅仅是在主表中这里是我的代码的功能摘录：续集模型设置： const Profile = sequelize.define('profiles', { // Database columns: profile_id: { type: Sequelize.STRING, primaryKey

因此，我使用Sequelize创建了这个查询，以便在数据库中查找配置文件，但我希望能够使用存储在不同（子）表/模型中的条件查找结果，而不仅仅是在主表中

这里是我的代码的功能摘录：

续集模型设置：

const Profile = sequelize.define('profiles',
    { // Database columns:
        profile_id: {
            type: Sequelize.STRING,
            primaryKey: true
        },
        user_name: {
            type: Sequelize.STRING,
            unique: true
        }
    });

const Email = sequelize.define('profiles_emails',
    { // Database columns:
        entry_id: {
            type: Sequelize.INTEGER,
            primaryKey: true,
            autoIncrement: true
        },
        owner_id: {
            type: Sequelize.STRING,
        },
        email_address: {
            type: Sequelize.STRING,
        }
    });

const Phone = sequelize.define('profiles_phones',
    { // Database columns:
        entry_id: {
            type: Sequelize.INTEGER,
            primaryKey: true,
            autoIncrement: true
        },
        owner_id: {
            type: Sequelize.STRING,
        },
        phone_number: {
            type: Sequelize.STRING,
        }
    });

Profile.hasMany(Email,
    { // Options:
        foreignKey: 'owner_id'
    });

Profile.hasMany(Phone,
    { // Options:
        foreignKey: 'owner_id'
    });

Profile.hasOne(Password,
    { // Options:
        foreignKey: 'owner_id'
    });

// TODO: Finding by email and phone does not work because finding in other tables than the parent table is not programed.
Profile
    .findAll({
       where: {
           [Op.or]: [
               { profile_id: '665C70C2A9F9' },
               { user_name: 'user1' },
               { email_address: 'user1@mail.com' }, 
               { phone_number: '554111222' }]
        },
        include: [Phone, Email], // Tables that I want to fetch data from.
    })
    .then(function(data) {
        if (data) { console.log('Number of rows found: ' + data.length, JSON.stringify(data)) }
        else { console.log('No entries found.') }
    })
    .catch(function(data) { console.error('An error occurred while making the query:\n' + data) });

建立关联：

const Profile = sequelize.define('profiles',
    { // Database columns:
        profile_id: {
            type: Sequelize.STRING,
            primaryKey: true
        },
        user_name: {
            type: Sequelize.STRING,
            unique: true
        }
    });

const Email = sequelize.define('profiles_emails',
    { // Database columns:
        entry_id: {
            type: Sequelize.INTEGER,
            primaryKey: true,
            autoIncrement: true
        },
        owner_id: {
            type: Sequelize.STRING,
        },
        email_address: {
            type: Sequelize.STRING,
        }
    });

const Phone = sequelize.define('profiles_phones',
    { // Database columns:
        entry_id: {
            type: Sequelize.INTEGER,
            primaryKey: true,
            autoIncrement: true
        },
        owner_id: {
            type: Sequelize.STRING,
        },
        phone_number: {
            type: Sequelize.STRING,
        }
    });

Profile.hasMany(Email,
    { // Options:
        foreignKey: 'owner_id'
    });

Profile.hasMany(Phone,
    { // Options:
        foreignKey: 'owner_id'
    });

Profile.hasOne(Password,
    { // Options:
        foreignKey: 'owner_id'
    });

// TODO: Finding by email and phone does not work because finding in other tables than the parent table is not programed.
Profile
    .findAll({
       where: {
           [Op.or]: [
               { profile_id: '665C70C2A9F9' },
               { user_name: 'user1' },
               { email_address: 'user1@mail.com' }, 
               { phone_number: '554111222' }]
        },
        include: [Phone, Email], // Tables that I want to fetch data from.
    })
    .then(function(data) {
        if (data) { console.log('Number of rows found: ' + data.length, JSON.stringify(data)) }
        else { console.log('No entries found.') }
    })
    .catch(function(data) { console.error('An error occurred while making the query:\n' + data) });

执行：

const Profile = sequelize.define('profiles',
    { // Database columns:
        profile_id: {
            type: Sequelize.STRING,
            primaryKey: true
        },
        user_name: {
            type: Sequelize.STRING,
            unique: true
        }
    });

const Email = sequelize.define('profiles_emails',
    { // Database columns:
        entry_id: {
            type: Sequelize.INTEGER,
            primaryKey: true,
            autoIncrement: true
        },
        owner_id: {
            type: Sequelize.STRING,
        },
        email_address: {
            type: Sequelize.STRING,
        }
    });

const Phone = sequelize.define('profiles_phones',
    { // Database columns:
        entry_id: {
            type: Sequelize.INTEGER,
            primaryKey: true,
            autoIncrement: true
        },
        owner_id: {
            type: Sequelize.STRING,
        },
        phone_number: {
            type: Sequelize.STRING,
        }
    });

Profile.hasMany(Email,
    { // Options:
        foreignKey: 'owner_id'
    });

Profile.hasMany(Phone,
    { // Options:
        foreignKey: 'owner_id'
    });

Profile.hasOne(Password,
    { // Options:
        foreignKey: 'owner_id'
    });

// TODO: Finding by email and phone does not work because finding in other tables than the parent table is not programed.
Profile
    .findAll({
       where: {
           [Op.or]: [
               { profile_id: '665C70C2A9F9' },
               { user_name: 'user1' },
               { email_address: 'user1@mail.com' }, 
               { phone_number: '554111222' }]
        },
        include: [Phone, Email], // Tables that I want to fetch data from.
    })
    .then(function(data) {
        if (data) { console.log('Number of rows found: ' + data.length, JSON.stringify(data)) }
        else { console.log('No entries found.') }
    })
    .catch(function(data) { console.error('An error occurred while making the query:\n' + data) });

“email_address”和“phone_number”列存储在不同的子表中，并且Sequelize关联已经成功建立

从实用角度解释：我希望能够通过电话和电子邮件获取用户，即使这些标准在不同的相关模块中

你知道怎么做吗？我已经试过了，但没有成功：

根据Vivek Doshi的建议进行更新：

const Profile = sequelize.define('profiles',
    { // Database columns:
        profile_id: {
            type: Sequelize.STRING,
            primaryKey: true
        },
        user_name: {
            type: Sequelize.STRING,
            unique: true
        }
    });

const Email = sequelize.define('profiles_emails',
    { // Database columns:

        },
        owner_id: {
            type: Sequelize.STRING,
        },
        email_address: {
            type: Sequelize.STRING,
        }
    });

const Phone = sequelize.define('profiles_phones',
    { // Database columns:
        entry_id: {
            type: Sequelize.INTEGER,
            primaryKey: true,
            autoIncrement: true
        },
        owner_id: {

        },
        phone_number: {

    });

Profile.hasMany(Phone,
    { // Options:
        foreignKey: 'owner_id'
    });

Profile.hasOne(Password,
    { // Options:

    });

    .findAll({
       where: {
           [Op.or]: [
               { profile_id: '665C70C2A9F9' },
               { user_name: 'user1' },
               { email_address: 'user1@mail.com' }, 
               { phone_number: '554111222' }]
        },
        include: [Phone, Email], // Tables that I want to fetch data from.
    })
    .then(function(data) {
        if (data) { console.log('Number of rows found: ' + data.length, JSON.stringify(data)) }
        else { console.log('No entries found.') }
    })
    .catch(function(data) { console.error('An error occurred while making the query:\n' + data) });

下面是应用的第一个建议：

Profile
    .findAll({
        where: {
            [Op.or]: [
                { profile_id: '665C70C2A9F9' },
                { user_name: 'user1' },
                { '$profiles_emails.email_address$': 'user1@mail.com' },
                { '$profiles_phones.phone_number$': '554111222' }
            ],
        },
        include: [Phone, Email], // Tables that I want to fetch data from.
        limit: 5 // Limit of profiles to look for.
    })
    .then(function(data) {
        if (data) { console.log('Number of rows found: ' + data.length, JSON.stringify(data)) }
        else { console.log('No entries found.') }
    })
    .catch(function(data) { console.error('An error occurred while making the query:\n' + data) });

Profile
    .findAll({
        where: {
            [Op.or]: [
                { profile_id: '665C70C2A9F9' },
                { user_name: 'user1' },
            ],
        },
        include: [{
            model : Phone,
            where : { phone_number: '554111222' } ,
            required : false
        }, {
            model : Email,
            where : { email_address: 'user1@mail.com' } ,
            required : false
        }],
        limit: 5 // Limit of profiles to look for.
    })
    .then(function(data) {
        if (data) { console.log('Number of rows found: ' + data.length, JSON.stringify(data)) }
        else { console.log('No entries found.') }
    })
    .catch(function(data) { console.error('An error occurred while making the query:\n' + data) });

这会导致错误：

Executing (default): SELECT `profiles`.*, `profiles_phones`.`entry_id` AS `profiles_phones.entry_id`, `profiles_phones`.`owner_id` AS `profiles_phones.owner_id`, `profiles_phones`.`phone_number` AS `profiles_phones.phone_number`, `profiles_phones`.`verified` AS `profiles_phones.verified`, `profiles_phones`.`modified_time` AS `profiles_phones.modified_time`, `profiles_phones`.`modified_by` AS `profiles_phones.modified_by`, `profiles_emails`.`entry_id` AS `profiles_emails.entry_id`, `profiles_emails`.`owner_id` AS `profiles_emails.owner_id`, `profiles_emails`.`email_address` AS `profiles_emails.email_address`, `profiles_emails`.`verified` AS `profiles_emails.verified`, `profiles_emails`.`modified_time` AS `profiles_emails.modified_time`, `profiles_emails`.`modified_by` AS `profiles_emails.modified_by` FROM (SELECT `profiles`.`profile_id`, `profiles`.`user_name`, `profiles`.`modified_time`, `profiles`.`modified_by` FROM `profiles` AS `profiles` WHERE (`profiles`.`profile_id` = '665C70C2A9F9' OR `profiles`.`user_name` = 'user1' OR `profiles_emails`.`email_address` = 'user1@mail.com' OR `profiles_phones`.`phone_number` = '554111222') LIMIT 5) AS `profiles` LEFT OUTER JOIN `profiles_phones` AS `profiles_phones` ON `profiles`.`profile_id` = `profiles_phones`.`owner_id` LEFT OUTER JOIN `profiles_emails` AS `profiles_emails` ON `profiles`.`profile_id` = `profiles_emails`.`owner_id`;

An error occurred while making the query:
SequelizeDatabaseError: Unknown column 'profiles_emails.email_address' in 'where clause'

下面是应用的第二个建议：

Profile
    .findAll({
        where: {
            [Op.or]: [
                { profile_id: '665C70C2A9F9' },
                { user_name: 'user1' },
                { '$profiles_emails.email_address$': 'user1@mail.com' },
                { '$profiles_phones.phone_number$': '554111222' }
            ],
        },
        include: [Phone, Email], // Tables that I want to fetch data from.
        limit: 5 // Limit of profiles to look for.
    })
    .then(function(data) {
        if (data) { console.log('Number of rows found: ' + data.length, JSON.stringify(data)) }
        else { console.log('No entries found.') }
    })
    .catch(function(data) { console.error('An error occurred while making the query:\n' + data) });

Profile
    .findAll({
        where: {
            [Op.or]: [
                { profile_id: '665C70C2A9F9' },
                { user_name: 'user1' },
            ],
        },
        include: [{
            model : Phone,
            where : { phone_number: '554111222' } ,
            required : false
        }, {
            model : Email,
            where : { email_address: 'user1@mail.com' } ,
            required : false
        }],
        limit: 5 // Limit of profiles to look for.
    })
    .then(function(data) {
        if (data) { console.log('Number of rows found: ' + data.length, JSON.stringify(data)) }
        else { console.log('No entries found.') }
    })
    .catch(function(data) { console.error('An error occurred while making the query:\n' + data) });

其结果是：

Executing (default): SELECT `profiles`.*, `profiles_phones`.`entry_id` AS `profiles_phones.entry_id`, `profiles_phones`.`owner_id` AS `profiles_phones.owner_id`, `profiles_phones`.`phone_number` AS `profiles_phones.phone_number`, `profiles_phones`.`verified` AS `profiles_phones.verified`, `profiles_phones`.`modified_time` AS `profiles_phones.modified_time`, `profiles_phones`.`modified_by` AS `profiles_phones.modified_by`, `profiles_emails`.`entry_id` AS `profiles_emails.entry_id`, `profiles_emails`.`owner_id` AS `profiles_emails.owner_id`, `profiles_emails`.`email_address` AS `profiles_emails.email_address`, `profiles_emails`.`verified` AS `profiles_emails.verified`, `profiles_emails`.`modified_time` AS `profiles_emails.modified_time`, `profiles_emails`.`modified_by` AS `profiles_emails.modified_by` FROM (SELECT `profiles`.`profile_id`, `profiles`.`user_name`, `profiles`.`modified_time`, `profiles`.`modified_by` FROM `profiles` AS `profiles` WHERE (`profiles`.`profile_id` = 'user1' OR `profiles`.`user_name` = 'jorge') AND ( SELECT `owner_id` FROM `profiles_phones` AS `profiles_phones` WHERE (`profiles_phones`.`phone_number` = '9' AND `profiles_phones`.`owner_id` = `profiles`.`profile_id`) LIMIT 1 ) IS NOT NULL LIMIT 5) AS `profiles` INNER JOIN `profiles_phones` AS `profiles_phones` ON `profiles`.`profile_id` = `profiles_phones`.`owner_id` AND `profiles_phones`.`phone_number` = '9' LEFT OUTER JOIN `profiles_emails` AS `profiles_emails` ON `profiles`.`profile_id` = `profiles_emails`.`owner_id` AND `profiles_emails`.`email_address` = 'user1@mail.com';

这个可以工作并查找行。但它会获取与“main”模型的结果相关联的结果（即，通过userid/user_name查找数据，然后根据匹配的其他数据（电子邮件和电话）来确定这些结果是否伴随）。这不是我现在想要的，我希望能够使用其他表中的条件/列找到一个包含所有数据和相同结构的完整配置文件。

这就是使用Sequelize获得预期结果的方法

Profile
    .findAll({
       where: {
           [Op.or]: [
               { profile_id: '665C70C2A9F9' },
               { user_name: 'user1' }
           ]
        },
        include: [ { 
                model : Phone ,
                where : { phone_number: '554111222' } ,
                required : false // as you want it in OR relation relation
            }, { 
                model : Email
                where : { email_address: 'user1@mail.com' } ,
                required : false // as you want it in OR relation relation
            }]
    })

或

Profile
    .findAll({
       where: {
           [Op.or]: [
               { profile_id: '665C70C2A9F9' },
               { user_name: 'user1' },
               { '$profiles_emails.email_address$': 'user1@mail.com' }, 
               { '$profiles_phones.phone_number$': '554111222' }]
        },
        include: [Phone, Email], // Tables that I want to fetch data from.
    })

非常感谢。但不幸的是，它似乎也不起作用。第一个示例不会导致错误，但仍然无法从列email\u address和phone\u number中找到结果。在最后一个例子中，我得到了“SequelizeDatabaseError:Unknown column'profiles\u emails.email\u address'In'where子句'”。请发布您的错误，Sequalizei生成的原始查询用您的例子的结果更新了我的问题，如果有什么不清楚的地方，请告诉我：）提供的第二种解决方案的问题是，如果添加偏移量并限制where对象中使用的子表的列将是未知列。
