can you try this:
sequelize = new Sequelize('dashboard_development', 'dashboard', null, {
dialect: "postgres",
port: 5432,
define: {
underscored: true,
timestamps: false
},
sync: { force: true },
omitNull: true
})
Question
I'm moving the JSON api of my Rails app to Node.js. I'm using Sequelize as the ORM to access my data in my postgres DB.
However, when I try to use the findOrCreate() and it needs to create an record, something weird happen:
INSERT INTO "gameweeks" ("id","number","gw_pts","transfers","transfers_malus","team_id","captain_id","vice_captain_id","in_bank","team_value","overall_rank") VALUES (NULL,16,NULL,NULL,NULL,6,NULL,NULL,NULL,NULL,NULL) RETURNING *;
Executing (default): SELECT * FROM "gameweeks" WHERE "gameweeks"."team_id"=12 AND "gameweeks"."number"=16 LIMIT 1;
It seems it tries to create a record without any id and thus it throw the error
error: null value in column "id" violates not-null constraint
When it doesn't need to create a record (update or just read data) it works fine.
here is my code:
sequelize options
sequelize = new Sequelize('dashboard_development', 'dashboard', null, {
dialect: "postgres",
port: 5432,
define: {
underscored: true,
timestamps: false
},
sync: { force: true }
})
Model
gameweek.js:
module.exports = function(sequelize, DataTypes) {
return sequelize.define('gameweek', {
number: DataTypes.INTEGER,
gw_pts: DataTypes.INTEGER,
transfers: DataTypes.INTEGER,
transfers_malus: DataTypes.INTEGER,
team_id: DataTypes.INTEGER,
captain_id: DataTypes.INTEGER,
vice_captain_id: DataTypes.INTEGER,
in_bank: DataTypes.FLOAT,
team_value: DataTypes.FLOAT,
overall_rank: DataTypes.INTEGER
});
};
its associations:
global.db.Gameweek.belongsTo(global.db.Team)
.hasMany(global.db.Player, {as: "substitutes", joinTableName: "gameweeks_substitutes"})
.hasMany(global.db.Player, {joinTableName: "gameweeks_players"})
.belongsTo(global.db.Player, {as: "captain", foreignKey: "captain_id"})
.belongsTo(global.db.Player, {as: "vice_captain", foreignKey: "vice_captain_id"})
and the code where I use findOrCreate:
db.Team.find({where: {fpl_id: fplTeamId}}).complete(function (err, team){
if (err) throw err;
db.Gameweek.findOrCreate({team_id: team.id, number: gwNumber}).complete(function (err, gameweek, created) {
if (err) throw err;
// Do stuff with the returned gameweek
})
})
Can anybody help or point me in the right direction?
Thanks!
