Suggestion for dsl

[jeroenvandijk]

I've created this hack for hypertemplate: https://gist.github.com/1113898

It allows for having something like the following:

notifications {
  members(:collection => @notifications, :root => false) do |notification|
    id           notification.id
    title        notification.title
  end
}

This will return something like the following

{ "notifications":
  [
    {
      "id": 2,
      "title": "some title",
    }
  ]
}

Would je be willing to add something like this?

Of course! Is it backwards compatible?
The patch for json is also welcome!

Interesting, glad I read this first.

I had an issue, perhaps I was using the normal syntax improperly.

parent_model_name {
  id parent_model.id
  name parent_model.name

  @child_models.each do |child|
    child_model_name {
      id      child.id
      attr1   child.attr1
    }
  end
}

was producing JSON like this:

{ "child_model_name":
  [
    {
      "id": 1,
      "attr1": "some attr 1",
    },
    {
      "id": 2,
      "attr1": "another attr 1",
    }
  ]
}

Which was as expected. But if there was only one "child model" I would receive this (JSON)

{ "child_model_name":
  {
    "id": 1,
    "attr1": "some attr 1",
  }
}

Not as a JSON array. I was expecting it to return me an Array regardless if it only had one element. This of course works fine in XML.

Switching my hypertemplate syntax to:

id parent_model.id
name parent_model.name

members(:collection => @child_models, :root => 'child_model_name') do |child|
  id      child.id
  attr1   child.attr1
end

Seemed to address the issue, properly wrapping the single child in an array.

I excluded the parent model wrapper stuff in my late code samples.

I think this is my misunderstanding, what I needed could be accomplished regardless of the hack, I believe.

I just needed to use the members call regardless, though I was under the impression that 'members' is a deprecated method. If that is true, then how would you get this behavior? AR:Collection?
