如何将“ where”和“ on”与“ Op.or”相连？

Question

我的目标是进行多方查询，现在我知道如何使用sql来实现它，代码如下，但是我不知道如何使用续集来实现它。

续集4.42.0 mysql2 1.6.4

课程模式：

'use strict';
module.exports = (sequelize, DataTypes) => {
    const course = sequelize.define('Course', {
        name: {
            allowNull: false,
            type: DataTypes.STRING
        },
        description: {
            type: DataTypes.TEXT
        },
        thumbnail: {
            type: DataTypes.STRING
        },
        program: {
            type: DataTypes.STRING
        },
        free: {
            allowNull: false,
            type: DataTypes.TINYINT
        },
        state: {
            allowNull: false,
            type: DataTypes.TINYINT
        }
    }, {
        tableName: 't_course'
    });

    course.associate = function (models) {
        // 多对多关系映射
        models.Course.belongsToMany( models.Organization, {
            through: models.Organization_Course
        });
    };

    return course;
};

组织模型：

'use strict';

module.exports = (sequelize, DataTypes) => {
    const organization = sequelize.define('Organization', {
        name: {
            allowNull: false,
            type: DataTypes.STRING
        },
        type: {
            allowNull: false,
            type: DataTypes.ENUM,
            values: ['school', 'agency']
        }
    }, {
            tableName: 't_organization',
        }
    );

    organization.associate = function (models) {
        models.Organization.belongsTo(models.District);

        // 多对多关系映射
        models.Organization.belongsToMany( models.Course, {
            through: models.Organization_Course
        });

        models.Organization.hasMany(models.User);
    };

    return organization;
};

Organization_Course模型：

'use strict';

module.exports = (sequelize, DataTypes) => {
    const organization_course = sequelize.define('Organization_Course', {}, {
            tableName: 'r_organization_course',
        }
    );

    // organization_course.associate = function (models) {

    // };

    return organization_course;
};

mysql代码：

SELECT `Course`.`id`, `Course`.`name`, `Course`.`description`, `Course`.`thumbnail`, `Course`.`program`
    , `Course`.`free`, `Course`.`state`, `Course`.`created_at`, `Course`.`updated_at`, `Course`.`deleted_at`
    , `Organizations`.`id` AS `Organizations.id`, `Organizations`.`name` AS `Organizations.name`, `Organizations`.`type` AS `Organizations.type`, `Organizations`.`created_at` AS `Organizations.created_at`, `Organizations`.`updated_at` AS `Organizations.updated_at`
    , `Organizations`.`deleted_at` AS `Organizations.deleted_at`, `Organizations`.`district_id` AS `Organizations.district_id`, `Organizations->Organization_Course`.`created_at` AS `Organizations.Organization_Course.created_at`, `Organizations->Organization_Course`.`updated_at` AS `Organizations.Organization_Course.updated_at`, `Organizations->Organization_Course`.`deleted_at` AS `Organizations.Organization_Course.deleted_at`
    , `Organizations->Organization_Course`.`course_id` AS `Organizations.Organization_Course.course_id`, `Organizations->Organization_Course`.`organization_id` AS `Organizations.Organization_Course.organization_id`
FROM `t_course` `Course`
    INNER JOIN (`r_organization_course` `Organizations->Organization_Course`
        INNER JOIN `t_organization` `Organizations`
        ON `Organizations`.`id` = `Organizations->Organization_Course`.`organization_id`
            AND (`Organizations->Organization_Course`.`deleted_at` > '2019-04-12 21:18:04'
                OR `Organizations->Organization_Course`.`deleted_at` IS NULL))
    ON `Course`.`id` = `Organizations->Organization_Course`.`course_id`
        AND ((`Organizations`.`deleted_at` > '2019-04-12 21:18:04'
                OR `Organizations`.`deleted_at` IS NULL)
            AND (`Organizations`.`id` = 3 or `Course`.`free` = 1))
WHERE (`Course`.`deleted_at` > '2019-04-12 21:18:04'
        OR `Course`.`deleted_at` IS NULL);

最重要的部分：AND（Organizations。id = 3或Course。free = 1）） 我不知道如何用续集来实现它。
