Sequelize.js delete query?

For anyone using Sequelize version 3 and above, use:

Model.destroy({
    where: {
        // criteria
    }
})

Sequelize Documentation - Sequelize Tutorial

I've searched deep into the code, step by step into the following files:

https://github.com/sdepold/sequelize/blob/master/test/Model/destroy.js

https://github.com/sdepold/sequelize/blob/master/lib/model.js#L140

https://github.com/sdepold/sequelize/blob/master/lib/query-interface.js#L207-217

https://github.com/sdepold/sequelize/blob/master/lib/connectors/mysql/query-generator.js

What I found:

There isn't a deleteAll method, there's a destroy() method you can call on a record, for example:

Project.find(123).on('success', function(project) {
  project.destroy().on('success', function(u) {
    if (u && u.deletedAt) {
      // successfully deleted the project
    }
  })
})

Don't know if the question is still relevant but I have found the following on Sequelize's documentation.

User.destroy('`name` LIKE "J%"').success(function() {
    // We just deleted all rows that have a name starting with "J"
})

Hope it helps!

This example shows how to you promises instead of callback.

Model.destroy({
   where: {
      id: 123 //this will be your id that you want to delete
   }
}).then(function(rowDeleted){ // rowDeleted will return number of rows deleted
  if(rowDeleted === 1){
     console.log('Deleted successfully');
   }
}, function(err){
    console.log(err); 
});
