Seems quite strange. This object from contentful looks pretty straight forward to me :)

Quick workaround: format.json { render json: districts.map(&:raw) } but without cache.

with cache: i need to return the #raw data in my cache

      Rails.cache.fetch(some_key) do
        all.load.map(&:raw)
      end

and then i lose the attribute accessors in my rails views, right?

.raw also removes all nested DynamicEntry stuff. This is pretty much a show-stopper for me :(

Hey @Frexuz,

The 0.x version of the CDA SDK is not serializable.

Please update to a newer release, 1.x (works with contentful_model 0.2.0) and 2.x (works with current master) are properly serializable.

Cheers

[Frexuz]

Not sure what's going on here :)

When im installing or updating contentful_mode, i get these versions

    contentful (0.12.0)
      http (~> 1.0)
      json (~> 1.8)
      multi_json (~> 1)
    contentful-management (1.10.1)
      http (> 1.0, < 3.0)
      json (~> 1.8)
      multi_json (~> 1)
    contentful_model (0.2.0)
      activesupport
      contentful (~> 0.9)
      contentful-management (~> 1.0)
      redcarpet
      require_all

So I can't update to 1.x because of ~> 0.9

So i tried master, but then I get this error on boot.

Hi @Frexuz,

Please add gem 'require_all', '~> 1.0' to your Gemfile.

This dependency will be removed in the next release. Which I'm expecting to release within April, as I'm starting active development again in this gem next week.

Cheers

[dlitvakb]

Current master has require_all removed.

Release of 1.0.0 version is scheduled for May 2nd.

Cheers
