I’ve got a model attribute whose type is ‘json’ that I’d like to edit within RailsAdmin’s interface. Based on the name of your gem it seems like a good fit - but I don’t know how to use it ? I did try installing it hoping that through the ‘magic of rails’ (perhaps via introspection) it would just work - but it did not.

How does one use this gem ?

Thanks

I'm sorry, I didn't got the time to write a proper readme and release. I'm also not sure if this package runs properly on current releases of ruby, rails and rails-admin. Please advice! I do use it in 2 production apps without any problems though :)

Some notes to get you on the way:

• You can give the column where you're storing json a type of text instead of json. I don't have any experience with the json-type, but text will work fine.
• You'd have to do the parsing (when you're rendering a page in the frontend) yourself, this is only a interface for RailsAdmin to structure a json-blob.
• In initializers/rails_admin.rb, add the following config for your column (components_json in my case)

field :components_json, :json_editor do
  label 'Components'
  help ''

  schema do
    model 'image' do |c|
      c.label 'Image'
      c.field :image, :picker do |f|
        f.picker model: Image, preview_image_field: :cdn_url
      end
      c.field :caption, :string
      c.field :size, :enum do |f|
        f.enum ['large', 'small']
      end
      c.field :modal_enabled, :boolean do |f|
        f.label 'Fullscreen'
      end
    end

    model 'quote' do |c|
      c.field :body, :text
      c.field :cite, :string
    end

    model 'image-text-list' do |c|
      c.label 'List of images and text'
      c.field :items, :list do |f|
        f.list ['image-text-list-item']
      end
    end

    model 'inset' do |c|
      c.label 'Inset'
      c.field :body, :text
      c.field :components, :list do |f|
        f.list ['image-text-list'], max_length:1
      end
    end

    model 'video' do |c|
      c.label 'Video'
      c.field :vimeo_url, :string
    end

    # and so on...
  end
end

I think those are the options and types you have. I'll be happy to assist further on (and hopefully make a proper release of this any time soon..)

You could also take a look at lib/rails_admin_json_editor.rb and app/views/rails_admin_json_editor/main/component_fields for further options.
