Looking at the source code, it seams clear how ember-model does the DELETE
operation:
deleteRecord: function(record) {
var primaryKey = get(record.constructor, 'primaryKey'),
url = this.buildURL(record.constructor, get(record, primaryKey)),
self = this;
return this.ajax(url, record.toJSON(), "DELETE").then(function(data) {
self.didDeleteRecord(record, data);
});
}
basically the resulting format is: DELETE /books/123 + JSON body
.
If your backend expects something else then the only way to change it would be to rewrite the deleteRecord
for your custom needs. But IMO the simplest thing you could do is to just ignore the JSON body
.
Hope it helps.
