續集多對多關聯連接表不填充

我在兩個模型之間有多對多關聯Hospital和Contact。在聯繫人記錄中添加，但在關聯表hospitals_contacts中沒有條目。 sequelize生成外鍵contact_id和hospital_id作爲組合主鍵。續集多對多關聯連接表不填充

接觸模型

module.exports = function(sequelize, DataTypes) { 
    var Contact = sequelize.define("Contact", { 

     job_title: DataTypes.STRING, 
     first_name: DataTypes.STRING, 
     last_name: DataTypes.STRING, 
     archived: DataTypes.BOOLEAN, 
     primary_email: { 

      type: DataTypes.STRING, 
      validate: { 
       isEmail: true 
      } 
     }, 
     business_number: DataTypes.STRING, 
     number_extension: DataTypes.STRING, 
     fax_number: DataTypes.STRING 

    }, { 

     underscored:'true', 
     tableName: 'contacts', 
     createdAt: false, 
     updatedAt: false, 

     classMethods: { 
      associate: function(models) { 
       Contact.belongsToMany(models.Hospital, { through: 'hospitals_contacts'});  
       Contact.belongsTo(models.Type); 
       Contact.belongsTo(models.Region) 
      } 
     }, 
    }); 



    return Contact; 
};

醫院模式

module.exports = function(sequelize, DataTypes) { 

    var Hospital = sequelize.define("Hospital", { 

     name: DataTypes.STRING, 
     mak_code: DataTypes.STRING, 
     licensed_tm_lab: DataTypes.BOOLEAN 

    }, { 

     underscored:'true', 
     tableName: 'hospitals',  
     createdAt: false, 
     updatedAt: false, 

     classMethods: { 
      associate: function(models) { 

       Hospital.belongsToMany(models.Contact, { through: 'HospitalsContacts'}); 
       Hospital.belongsTo(models.Address) 
      } 
     } 
    }); 

    return Hospital; 
};

API端點添加聯繫人

var hospitalInstance = models.Hospital; 
var contactData = req.body; 

models.Contact.create({ 
    first_name: contactData.first_name, 
    last_name: contactData.last_name, 
    type_id: contactData.type, 
    job_title: contactData.job_title, 
    primary_email: contactData.email, 
    business_number:contactData.phone_number, 
    fax_number:contactData.fax, 
    number_extension:contactData.extension, 
    region_id: contactData.region, 
    committee_id: contactData.committee, 
    archived: false, 
    hospitalInstance: {id:contactData.hospital} 
    }, 
    { 
     include: [hospitalInstance] 

    });

我建議你嘗試以下方法：

更改你的「穿越」在聯繫的屬性相匹配的一個醫院：HospitalsContacts，所以你必須：

Contact.belongsToMany(models.Hospital, { through: 'HospitalsContacts'}); //Contact 
Hospital.belongsToMany(models.Contact, { through: 'HospitalsContacts'}); //Hospital

現在我假設你已經有了醫院創建並且只是想創建一個與該醫院相關的新聯繫人，這是否正確？如果是這樣的話：

var hospital = (...) 

hospital.createHospitalContact({ 
    first_name: contactData.first_name, 
    last_name: contactData.last_name, 
    type_id: contactData.type, 
    job_title: contactData.job_title, 
    primary_email: contactData.email, 
    business_number:contactData.phone_number, 
    fax_number:contactData.fax, 
    number_extension:contactData.extension, 
    region_id: contactData.region, 
    committee_id: contactData.committee, 
    archived: false, 
}).then(function(contact) { 
    //Do something 
})
