My app is saving a socket related information into a socketlist table. The idea is if the entry with the socket_id does not exist, then create an entry in postgres table. otherwise to do nothing. Here is the code:
await SocketList.findOrCreate({ where: {socket_id : socket_id, active: true}, default: {event_id: event_id, user_id: user_id, server_id: server_id}});
sequelizejs 4.42.0 is used. The socketlist table is empty but the above code throws the error below:
Executing (325bc621-414d-4e3f-9f2b-230f66537631): START TRANSACTION;

Here is the model definition:
const SocketList = db.define('socketlist', {
id: {type: Sql.INTEGER,
primaryKey:true,
min: 1
},
user_id: { type: Sql.INTEGER
},
socket_id: {type: Sql.STRING,
unique: true,
min: 1
},
event_id: {type: Sql.INTEGER,
min: 1
},
server_id: {type: Sql.STRING
},
active: {type: Sql.BOOLEAN,
defaultValue: true,
},
}....
答案 0 :(得分：1)
you have to create data include id what about try this?
id: {
type: Sql.INTEGER,
primaryKey:true,
autoIncrement: true
}
