}
}, { freezeTableName: true });
Users.associate = function(models) {
Users.hasOne(models.login, {
foreignKey: 'user_id',
as: 'loginDetails'
});
};
Users.associate = function(models) {
Users.hasMany(models.customer_query, {
foreignKey: 'user_id',
as: 'queryDetails'
});
};
return Users;
};

isEmail: true
},
password: {

foreignKey: 'role_id',
onDelete: 'CASCADE'
});
};
return Login;
};

questionDetails.associate = function(models) {
questionDetails.belongsTo(models.users, {
foreignKey: 'created_by',
onDelete: 'CASCADE'
});
};
return questionDetails;
};

You only have to define associate once. When you define it the second time you're actually overwriting it. So for the User model you should actually do...
Users.associate = function(models) {
Users.hasOne(models.login, {
foreignKey: 'user_id',
as: 'loginDetails'
});
Users.hasMany(models.customer_query, {
foreignKey: 'user_id',
as: 'queryDetails'
});
};
Do similarly for your login model as you are also overwriting the associate function there.
Good luck! :)
