Question

I’ve got this code currently:

handleSubmit: function(e)
{
    var to_bucket = this.$('.transaction_bucket').val();

    // Move all the transactions for this bucket to the selected bucket
    window.app.model.active_transactions.each(
        function(transaction)
        {
            transaction.set({bucket_id: to_bucket});
            transaction.save();
        }
    );

    this.model.destroy({success: function() { window.app.model.buckets.fetch();}});
}

How can I modify this so that the destroy only triggers once all the _.each ajax transactions happen? If I had one previous ajax request, I would just use the success: parameter, but I can’t do that here.

What’s the right way to do this in backbone?

Answer 1

One possible solution would be to create a custom API method that took the transactions as parameters and did the job on the server side. This would reduce https requests and increase performance as well.
