Arguments / constructor

[offthegrass]

with this example from the demo:

mixins: -> [
  ....
  new StorageMixin Values, 'value', => @data().id
]

class StorageMixin extends BlazeComponent
  constructor: (@collection, @fieldName, @selector) ->

I would like to change

new StorageMixin Values

to something like

new StorageMixin @data().collection

so I can do

{{> MyComponent collection='Values'}}

I do want the component to re-render if the collection changes, so do I use args in the MyComponent constructor? what is the correct way to do this?

[offthegrass]

{{#MyComponent args collection='Values'}}

constructor: (args) ->
        @collection = eval(args.hash.collection)

this works.

Why eval there? This looks really wrong, strange, unnecessary?

[rclai]

Use window[args.hash.collection] instead dude.

[mitar]

Oh, you want to access a global symbol? Oh. :-)

I prefer then putting in the top level of a file:

globals = @

And then you can use globals[args.hash.collection].
