When I try to create a new Conversation item Sequelize will return an object with id: null
eventhough there is an valid id in the database. How can I get Sequelize to return the last inserted id to the newly created item?
Conversation.create({
type: 'private',
createdBy: 1,
}).then(conversation => {
reply(conversation);
});
Will return
{
"type": "conversations",
"id": null,
"createdBy": 1,
"created_at": "2016-03-18T01:47:48.000Z"
}
My code:
const Conversation = model.define('Conversation', {
id: {
type: Sequelize.INTEGER,
primaryKey: true,
},
type: {
type: Sequelize.ENUM,
values: ['private', 'group'],
validate: {
isIn: ['private', 'group'],
},
},
createdBy: {
type: Sequelize.INTEGER,
field: 'created_by',
},
}, {
tableName: 'conversations',
timestamps: true,
createdAt: 'created_at',
updatedAt: false,
getterMethods: {
type: () => 'conversations',
},
});
const User = model.define('User', {
id: {
type: Sequelize.INTEGER,
primaryKey: true,
},
firstName: {
type: Sequelize.STRING,
field: 'first_name',
allowNull: false,
},
lastName: {
type: Sequelize.STRING,
field: 'last_name',
allowNull: true,
},
email: {
type: Sequelize.STRING,
allowNull: false,
},
profileImg: {
type: Sequelize.STRING,
field: 'profile_img',
allowNull: false,
},
password: Sequelize.STRING,
}, {
tableName: 'users',
timestamps: true,
createdAt: 'created_at',
updatedAt: 'updated_at',
getterMethods: {
type: () => 'users',
},
});
Conversation.belongsToMany(User, {
foreignKey: 'conversation_id',
otherKey: 'user_id',
through: 'conversation_user',
timestamps: false,
});
User.belongsToMany(Conversation, {
as: 'conversations',
foreignKey: 'user_id',
otherKey: 'conversation_id',
through: 'conversation_user',
timestamps: false,
});
You can use JSON datatype of field in Sequelize (this corresponds to JSON datatype in PostgreSQL). const User = sequelize. define('User', { name: { type: DataTypes. STRING, allowNull: false }, age: { type: DataTypes.
sequelize fails to load a model if a nested include has a where clause that returns no models.. to ensure it doesnt fail completely, you can set a required: false clause along with the where clause.. this makes sequelize return a blank array instead of failing the load completely.. Save this answer.
A very useful shortcut: the create method Sequelize provides the create method, which combines the build and save methods shown above into a single method: const jane = await User.create({ name: "Jane" }); // Jane exists in the database now!
Yo need to put autoIncrement: true
in id
field:
id: {
type: Sequelize.INTEGER,
primaryKey: true,
autoIncrement: true,
}
Personally I would advice to skip the id
column as sequalize
does it automatically for you and works nicely.
hope it helps :)
