[SOLVED] Iced coffee script with multiple callbacks

Iced coffee script with multiple callbacks

I'm using Iced coffescript with upshot js when I am refreshing multiple data sources. The refresh method has TWo call backs one for success and one for error and I want to wait for each call to make either callback.

I can't see how to do this with idced coffescript without making an additional function. My question is - is there a more elegant way that I can defer to one of multiple callbacks?

This is the code I have currently:

refreshMe = (key, value, result) =>
    value.refresh(
    (success)=>
            result success
    ,
    (fail, reason, error)=>
        result undefined, fail
    )
@refresh = () =>                
success={}
fail={}
await
    for key, value of @dataSources
    refreshMe key, value, defer success[key], fail[key]

Solution

This is the only way I have found to do it too. I'm using it in Backbone and wrap (for example) a model's @save function with an @icedSave:

# An IcedCoffeescript friendly version of save
icedSave: (callback) ->
    @save {},
        success: (model, response) -> callback(true, model, response)
        error: (model, response) -> callback(false, model, response)
