Modify attributes about rabl

[nesquena]

Doing this should be very easy. Don't yield a block to attribute, just do:

node :small_image_url do |tour|
 root_url + tour.small_image_url
end

node :large_image_url do |tour|
 root_url + tour.small_image_url
end

To create custom nodes and transform values just use the node method which yields the object. Close this once you try.

Interesting idea though, I don't mind the attribute block transformation idea. Also not sure how you will get root_url my recommendation is setting it to an instance variable to pass the data along or find another way to access it. RABL is currently unable to access route urls directly as you are trying to do here. Interesting to see all the different use cases

Thanks for the quick reply, that code really helped. This is what I ended up doing (in case this helps anyone).

collection @tours
attributes :created_at, :days_required, :description, :fee_description, :fee_scale, :id, :name, :published, :updated_at, :lat, :lng

node :small_image_url do |tour|
 @root_url + tour.small_image_url
end
node :large_image_url do |tour|
 @root_url + tour.large_image_url
end

I did as you suggested adding creating a @root_url. I was under the impression that you could access view helpers, however I would have to say, I spend about 10 hours (maybe less) getting everything work and this method took me about an hour to flesh out the same, much cleaner solution. Thanks a bunch.

p.s. Why does my markdown never work!

It wouldnt be hard to add helpers to rabl, I personally never ran into the need to use helpers yet in my RABL, although getting it to work with view helpers should be trivial. Might be a good feature, I will add an issue, thanks.

Np. I'll try to help with documentation if I get a chance if you need someone, cause this gem is pretty amazing.

Added the issue here, will try to get to it soon: #19

Glad you like it, it has made our lives building APIs much easier. I would love any help you could provide with documentation or code. This gem is still very young but I think it has a lot of potential if I can get others to help pitch in.
