Backbone model.save() not appending ID to end of URL

Question

I have an issue with a backbone PUT request returning 405 (Method not allowed). This is happening because the model.save() in the code is not sending to the model url with the ID of the model on the end. This is the PUT. ``` Remote Address:::1:670 Request URL:http://localhost:670/api/contacts Request Method:PUT Status Code:405 Method Not Allowed Request Headersview source Accept:application/json, text/javascript, */*; q=0.01 Accept-Encoding:gzip,deflate,sdch Accept-Language:en-GB,en-US;q=0.8,en;q=0.6 Authorization:Bearer YLPwKSpBsBrFUemRHdjz....

Accepted Answer

Setting `Model.url` just gives the model a constant URL. If you want the model ID appended, then you need to specify `Model.urlRoot` instead. This will generate URLs of the form "/api/contacts/id":

```
var ContactModel = Backbone.Model.extend({
  urlRoot: "http://localhost:670/api/contacts"        
});
```

Alternatively, if the model is stored in a collection, then you could set `Collection.url` to the same. See the notes for `Model.url`:

Delegates to Collection#url to generate the URL, so make sure that you have it defined, or a urlRoot property, if all models of this class share a common root URL. A model with an id of 101, stored in a Backbone.Collection with a url of "/documents/7/notes", would have this URL: "/documents/7/notes/101"
