I have a Model and I have configured a Ajax proxy to handle its remote operations.
Initially, I have not used a url property as I wanted to define specific url for all specific APIs.
The create, read and update work just fine, but when I try to delete a record, it raises an error stating that I can not do it without defining the url property.
Therefore, I have set the url just to handle the delete operation.
Delete is a keyword in JS, we use "destroy" for that parameter.
Ops! Sorry, my mistake! Now it is working.
