Sequelize: Error: Error: Table1 is not associated to Table2 - mysql

Question

I am trying to create the following associations using sequelize but I keep getting the following error “Error: Error: customer is not associated to order!”. I have bi-directional associations according to what I found in the documentation. I am confused about what the problem could be because when I look into the database tables I can see the foreign keys. For this example, I am trying to pull the order and customer associated with the particular order. Technically, I could do three seaprate db pull but that seems inefficient as opposed to joins.
'use strict';

var user = sequelize.define('user', {

}, {

// associations can be defined here
this.hasMany(models.order);
}
}
});
user.hook('afterCreate', function(usr, options) {
//hash the password
return user.update({ password: passwd }, {

}
});
});
return user;
};

});
return order;

}, {

}
});
customer.hook('afterCreate', function(cust, options) {
//generate the customer number
return customer.update({ customernumber: custnumber }, {
where: {
id: cust.id
}
});
});
return customer;
};
Here is the constructor and method inside of a repository class I want to join
constructor(model){
super(model.order);
this.currentmodel = model;
}
findById(id){
let that = this;
return new Promise(
function(resolve, reject) {
that.model.find({
where: { id: id },
include: [ that.currentmodel.customer, that.currentmodel.user ]
})
.then(function(order){
resolve(order);
})
.catch(function(err){
reject(err);
})
});
}
I have reviewed the documentation and searched the internet looking for a fix to this issue but I am not finding any answers. Could someone please shed some light on what I could be missing?
For the example above, I am trying to retrieve the user and the customer tied to the order record via the primary key. All of the findBy scenarios I have found so far would be getting a list of orders tied to the customer and user. What do I need to change in order to retrieve the order and customer whose foreign keys are tied to this order?

The problem is probably with how you are setting you association, kindly mention your strategy.
Following is working fine if you use the express index.js file setup and then query http://docs.sequelizejs.com/en/1.7.0/articles/express/
'use strict';
module.exports = function(sequelize, DataTypes) {
var customer = sequelize.define('customer', {
customernumber: DataTypes.STRING(30), //remove
customerspecificationid: DataTypes.INTEGER,
customertypeid: DataTypes.INTEGER,
sportid: DataTypes.INTEGER,
customername: DataTypes.STRING(20), //remove
address: DataTypes.STRING(30),
city: DataTypes.STRING(30),
state: DataTypes.STRING(30),
zipcode: DataTypes.STRING(30),
ordercomplete: DataTypes.BOOLEAN,
isactive: DataTypes.BOOLEAN
}, {
associate: function(models) {
// associations can be defined here
models.customer.hasMany(models.order);
}
});
customer.hook('afterCreate', function(cust, options) {
//generate the customer number
return customer.update({ customernumber: custnumber }, {
where: {
id: cust.id
}
});
});
return customer;
};
'use strict';
module.exports = function(sequelize, DataTypes) {
var order = sequelize.define('order', {
ponumber: DataTypes.STRING(30), //remove
orderdate: DataTypes.DATE,
shippingmethod: DataTypes.STRING(30),
shippingterms: DataTypes.STRING(30),
deliverydate: DataTypes.DATE,
paymentterms: DataTypes.STRING(30),
overridediscount: DataTypes.BOOLEAN,
shippingaddress: DataTypes.STRING(30),
shippingcity: DataTypes.STRING(30),
shippingstate: DataTypes.STRING(20),
shippingzipcode: DataTypes.STRING(10),
isactive: DataTypes.BOOLEAN
}, {
associate: function(models) {
// associations can be defined here
models.order.belongsTo(models.user);
models.order.belongsTo(models.customer);
}
});
order.hook('afterCreate', function(ord, options) {
//generate po number
return order.update({ ponumber: ponumbr }, {
where: {
id: ord.id
}//,
//transaction: options.transaction
});
});
return order;
};
'use strict';
module.exports = function(sequelize, DataTypes) {
var user = sequelize.define('user', {
username: DataTypes.STRING(30), //remove
password: DataTypes.STRING(255),
emailaddress: DataTypes.STRING(255),
firstname: DataTypes.STRING(30),
middlename: DataTypes.STRING(30), //remove
lastname: DataTypes.STRING(30),
approve: DataTypes.BOOLEAN,
roles: DataTypes.STRING(50),
isactive: DataTypes.BOOLEAN
}, {
classMethods: {
associate: function(models) {
// associations can be defined here
models.user.hasMany(models.order);
}
}
});
user.hook('afterCreate', function(usr, options) {
//hash the password
return user.update({ password: passwd }, {
where: {
id: usr.id
}
});
});
return user;
};
// index.js file where you shall associate the routes
var fs = require('fs')
, path = require('path')
, Sequelize = require('sequelize')
, lodash = require('lodash')
, sequelize = new Sequelize('sequelize_test', 'root', 'root')
, db = {}
fs.readdirSync(__dirname)
.filter(function(file) {
return (file.indexOf('.') !== 0) && (file !== 'index.js')
})
.forEach(function(file) {
var model = sequelize.import(path.join(__dirname, file))
db[model.name] = model
})
Object.keys(db).forEach(function(modelName) {
if (db[modelName].options.hasOwnProperty('associate')) {
db[modelName].options.associate(db)
}
})
// sequelize.sync({force: true})
module.exports = lodash.extend({
sequelize: sequelize,
Sequelize: Sequelize
}, db)
Put the above db code in respective files in db folder or whatever you like to name it and then you can use your query
var db = require('./db');
db.order.find({
where: { id: 0 },
include: [ db.customer, db.user ]
})
.then(function(order){
console.log(order)
})
