Question

(Rails 3 + backbone 0.53)
I am fetching data from my API on “/payments” url and it returns different kinds of payment data.

So the user can for example delete, let’s say a credit-card entry and it is synced backed to the server on

"/credit_cards".

The problem is that if I use Backbone.Sync with the syntax

Backbone.Sync('delete', @options.credit_cards.get('id')) 

it gives me an “A “url” property or function must be specified” error.

This makes sense as the model e.g.:

@options.credit_cards.get('id') 

does not exist in this case because credit_cards doesn’t store any data. I just wanna do a standard DELETE with Backbone.sync á la

"/credit_cards/:id" 

but just by specifying the id (which I receive from /payments) not the model (but the model/collection has the url…)

So my question is: 1.)
is there a way in backbone to use backbone.sync without actually storing data in a collection/model, more like a simple ajax request with jQuery.
Example:

Backbone.Sync('delete', "specify_a_url_here_with/#{id}"))

instead of using Backbone.Sync & $.ajax requests mixed.

2.) does that make sense at all or is there a better alternative.

Thanks a lot! I really love SO! Hope the question isn’t to weird. Phil

Answer 1

You can pass “url” and “data” to Backbone.Sync in “options”.

Backbone.sync(method, model, options) returns a $.ajax(params) where params.url and params.data reflect your model unless you exlicitly pass them in options.

So

Backbone.sync('delete', false, {url : "/credit_cards/1", data : ''}) 

should work.
