序列化一对多查询（包含）产生与X不相关的Y

Question

so i'm having problems with sequelize's one to many relationship, my associations are defined like this:

X.hasMany(Y, { as: 'Ys' });
Y.belongsTo(X, { as: 'X' });

and my findAll is here:

return X.findAll(
        {
            where: {
                something: something,
            },
            include: [{ model: db.Y, as: 'Ys' }]
        }
    );

and this is producing the error:

"error": "Y (Ys) is not associated to X!"

Not quite sure what i'm doing wrong here :/

Answer 1

There's some confusion on your associations

logically 'X' has many 'Ys', association should be X.hasMany(Y, {as: 'Ys'});

'Y' belongs to 'X' should be Y.hasMany(X, {as: 'X'});
