  Gobbled up my code. Maybe I got it right this time.

  @@@ruby class DataMapper::Collection def to_collected_json

  ['[', self.collect{|o| o.attributes.to_json}.join(', '), ']'].join
  
  

  end end

  One more try. Otherwise, see: http://pastie.org/305933.

  class DataMapper::Collection
    def to_collected_json
      ['[', self.collect{|o| o.attributes.to_json}.join(', '), ']'].join
    end
  end

  • Tag changed from “collection, json, serialization” to “collection, dm-serializer, json, serialization”

  A better way at the moment is Post.all.to_a.to_json

  That way it keeps the to_json options interface (you can specify :methods, :only, etc...)

  I must be doing something wrong.

  
  >> Post.all.to_a.to_json
   ~ SELECT "id", "url", "title" FROM "posts" ORDER BY "id", "title"
  => "[\"#<Post:0x286f4dc>\"]"

  >> Food.all(:limit => 2).to_a.to_json
  => "[{ "food_id": "01A10026", "name": "Beer, Ale", "description": "Alcoholic beverage made by brewing and fermenting " },{ "food_id": "01A10027", "name": "Beer, Bitter", "description": "Alcoholic beverage made by brewing and fermenting " }]"
  

  
  $ gem list | grep dm-serializer
  dm-serializer (0.9.6, 0.9.2)
  

  (though it's possible that isn't the actual 0.9.6 - I have a bit of a frakenstein setup at the moment because I've been hacking dm-serializer)

  as an aside - this only really works for JSON at the moment.

  Would merb-datamapper (0.9.9) be getting in the way of the behavior you're showing? I have the same dm-serializer gem installed: 0.9.6.

  I wouldn't have thought so

  
  $ gem list | grep merb_datamapper
  merb_datamapper (0.9.12, 0.9.10)
  

  Let me double check what I actually have installed, I'll get back to you. I suspect my hack works with the edge version of dm-serializer.

  Aside from that, we still need to get it working normally though :]

  I have fixed in my branch:

  http://github.com/xaviershay/dm-...

  in short, the json gem was adding Object#to_json which meant the Proxy that sits infront of Collection was not delegating it.

  • Title changed from “DataMapper::Collection Should Serialize to JSON” to “[PATCH] DataMapper::Collection Should Serialize to JSON”
  • Tag changed from “collection, dm-serializer, json, serialization” to “collection, dm-serializer, json, patch, serialization”

  • Title changed from “[PATCH] DataMapper::Collection Should Serialize to JSON” to “[FIXED] DataMapper::Collection Should Serialize to JSON”
  • Tag changed from “collection, dm-serializer, json, patch, serialization” to “collection, dm-serializer, json, serialization”

  This is now fixed in sam/dm-more, so will be in the 0.9.8 gem
