Creating associations in Sequelize migration












0















Nodejs. Sequelize 4.41. Try to make 2 models with relation many-to-many through another table. Running with sequelize-cli, for example...



sequelize model:generate --name Camera --attributes name:string,sn:string


Here is models



// Camera model

'use strict';

module.exports = (sequelize, DataTypes) => {
const Сamera = sequelize.define('Сamera', {
name: DataTypes.STRING,
sn: DataTypes.STRING
}, {});
Сamera.associate = function(models) {
// associations can be defined here
Camera.belongsToMany(models.Relay, {through: 'CameraRelay'});
};
return Сamera;
};


And



// Relay model

'use strict';

module.exports = (sequelize, DataTypes) => {
const Relay = sequelize.define('Relay', {
name: DataTypes.STRING,
sn: DataTypes.STRING,
channel: DataTypes.INTEGER
}, {});
Relay.associate = function(models) {
// associations can be defined here
Relay.belongsToMany(models.Camera, {through: 'CameraRelay'});
};
return Relay;
};


In documentation there are phrase




Belongs-To-Many associations are used to connect sources with multiple targets. Furthermore the targets can also have connections to multiple sources.



Project.belongsToMany(User, {through: 'UserProject'});
User.belongsToMany(Project, {through: 'UserProject'});



This will
create a new model called UserProject with the equivalent foreign keys
projectId and userId.




Migrations is



// create-relay

'use strict';
module.exports = {
up: (queryInterface, Sequelize) => {
return queryInterface.createTable('Relays', {
id: {
allowNull: false,
autoIncrement: true,
primaryKey: true,
type: Sequelize.INTEGER
},
name: {
type: Sequelize.STRING
},
sn: {
type: Sequelize.STRING
},
channel: {
type: Sequelize.INTEGER
},
createdAt: {
allowNull: false,
type: Sequelize.DATE
},
updatedAt: {
allowNull: false,
type: Sequelize.DATE
}
});
},
down: (queryInterface, Sequelize) => {
return queryInterface.dropTable('Relays');
}
};


And



//create camera
'use strict';
module.exports = {
up: (queryInterface, Sequelize) => {
return queryInterface.createTable('Сameras', {
id: {
allowNull: false,
autoIncrement: true,
primaryKey: true,
type: Sequelize.INTEGER
},
name: {
type: Sequelize.STRING
},
sn: {
type: Sequelize.STRING
},
createdAt: {
allowNull: false,
type: Sequelize.DATE
},
updatedAt: {
allowNull: false,
type: Sequelize.DATE
}
});
},
down: (queryInterface, Sequelize) => {
return queryInterface.dropTable('Сameras');
}
};


Why it doesn't create model CameraRelay and doesn't create migration for same model when I running migrate?
