How does group by works in sequelize?

Question

I am looking for group by queries through Sequelize and cannot seem to find any documentation.

I think you looking for something like this:

 Table.findAll({
   attributes: ['column1', 
     sequelize.fn('count', sequelize.col('column2'))], 
   group: ["Table.column1"]
 }).success(function (result) { });

Update: Newer versions of Sequelize uses .then instead of .success.

 Table.findAll({
   attributes: ['column1', 
     sequelize.fn('count', sequelize.col('column2'))], 
   group: ["Table.column1"]
 }).then(function (result) { });
