sequelize findAll sort order in nodejs


I'm trying to output all object list from database with sequelize as follow and want to get data are sorted out as I added id in where clause.

exports.getStaticCompanies = function () {
    return Company.findAll({
        where: {
            id: [46128, 2865, 49569,  1488,   45600,   61991,  1418,  61919,   53326,   61680]
        },
        attributes: ['id', 'logo_version', 'logo_content_type', 'name', 'updated_at']
    });
};

But the problem is after rendering, all data are sorted out as follow.

46128, 53326, 2865, 1488, 45600, 61680, 49569, 1418, ....

As I found, it's neither sorted by id nor name. Please help me how to solve it.


Solution

  • In sequelize you can easily add order by clauses.

    exports.getStaticCompanies = function () {
        return Company.findAll({
            where: {
                id: [46128, 2865, 49569,  1488,   45600,   61991,  1418,  61919,   53326,   61680]
            }, 
            // Add order conditions here....
            order: [
                ['id', 'DESC'],
                ['name', 'ASC'],
            ],
            attributes: ['id', 'logo_version', 'logo_content_type', 'name', 'updated_at']
        });
    };
    

    See how I've added the order array of objects?

    order: [
          ['COLUMN_NAME_EXAMPLE', 'ASC'], // Sorts by COLUMN_NAME_EXAMPLE in ascending order
    ],
    

    Edit:

    You might have to order the objects once they've been recieved inside the .then() promise. Checkout this question about ordering an array of objects based on a custom order:
