Questions & Ideas about rabl HOT 9 CLOSED

Hey thanks for your feedback, much appreciated. Here is some thoughts and answers.

1. I am the first to admit my API isn't perfect but the way you demonstrated is how I do it too. I use extends in the object to inherit the properties. I don't view that inheritance case as a place for partials. I tend to use partials exclusively in code blocks when I want access to the json hash for another object. I tend to use extends in most other cases as you showed there. I don't view it as too clumsy but if you have a better approach I am happy to consider it for the future.
2. I like this idea but for implementation reasons (when dealing with a collection of objects) with the way RABL is currently set up having access to the object in a collection directly isn't easily possible. It can only be accessed in a lambda and passed it at the time each object is rendered. I can imagine a refactoring of RABL that could support an current_object helper that achieves the effect but I probably won't be doing that personally anytime soon unless it becomes an essential use case for me. Thanks for the suggestion and I welcome a patch :)
3. I completely agree that child should accept an if lambda. In fact I am pretty sure it does or did. I use child with if blocks in a couple of my APIs. Are you absolutely certain that they don't work? Notice the call to resolve_conditions here: https://github.com/nesquena/rabl/blob/master/lib/rabl/builder.rb#L77. If this doesn't work it is a bug and I will fix that soon hopefully.

Thanks again for your feedback and for trying RABL.

This post was very helpful. It was not immediately clear how to reuse templates from the README.

child (:auto_judge, :if => lambda {|station| station._type == "HumanWorker"}) {....}

gives out <pre><code>(eval):7: syntax error, unexpected ',', expecting ')' child (:auto_judge, :if =&gt; lambda {|station| sta... ^

Is that a space after child? Might be the issue

child(:auto_judge, :if => lambda {|station| station._type == "HumanWorker"}) {....}

should work fine...what ruby are you using?

i'm using 1.9.2
child(:line,:if => lambda {@line!=nil}){... } still no effect??? i'm really stuck on this, am i doing something wrong???

@xecutioner If it really doesn't work, hopefully I can fix it in the next release, I will have to play around. In the meantime try to use:

child @line => :line do
  # ...
end unless @line.nil?

Closing this but adding a link the wiki, the bugs mentioned here should be fixed.

Seems bug is back
child (@products, :if => lambda {|product| product.active?}) do

eval):4: syntax error, unexpected ',', expecting ')'
child (@products, :if => lambda {|product| product.active?}) do

from rabl.

It might be the space before the paranthesis, can you try:

child @products, :if => lambda {|product| product.active?} do
# ...
end
