How do I tell backbone that the model is not new
backbone-model, backbone.js, javascript
Solution
Backbone determines the newness of a model by checking if an id is set :
isNew `model.isNew()`
Has this model been saved to the server yet? If the model does not yet have an `id`, it is considered to be new.
And when you save a model,
- if it is new, a POST request will be emitted,
- if it is an update (an id has been set), a PUT request will be sent
Backbone Sync documentation
And as noted by @JayC in the comments :
If there's an issue that the id can't literally be `id`, you can use `idAttribute` to say which is the "identity" or key field.
Problem
I have an object that's also saved in the server and I'm creating a Backbone model from that object. But when I save the model, it's doing a PUT request, which is not what I want. How to tell Backbone that the data is already in the server without doing a fetch?
