Backbone JS: how to disable sync for delete?
backbone.js, destroy, model
Solution
Since all the `destroy` method does is send a DELETE request and triggers `destroy`, simply triggering `destroy` is exactly what you're looking for.
model.trigger('destroy', model, model.collection, options);
Yeah, it feels a bit hackish, but that's pretty much all the Backbone code does anyway. If you want, and if you have a base model you extend from, you could add this as a method on that base model, and it might not feel quite so hackish.
Problem
I am dealing with a threaded comments collection, and when I delete a comment that has children, I do `model.destroy()` for this comment, and on the server side all its branches get deleted. I wrote a function that once a node is deleted from the tree, looks for all orphans and removes them too. So when I find orphans, I run `model.destroy()` on them too but because they're already deleted on the server, sync returns errors. Is there a way to disable sync for some `destroy()` calls?
