undefined method `deconstantize' for nil:NilClass about grape-active_model_serializers HOT 11 CLOSED

Thanks for providing that project, @ivan-garanin

I dug into our source code via your project and it looks like neither this gem or active_model_serializers have great support for non-ActiveRecord ORMs. Both gems key off of collection resources responding to a to_ary method that ActiveRecord has implemented for collections, but Sequel does not.

That said, I implemented some basic support for sequel that you can try out.
#74

I tested this against your project:

gem 'grape-active_model_serializers',
  github: 'ruby-grape/grape-active_model_serializers',
  branch: 'support-sequel'

Let me know if it works for you!

v1.5.1 has been released!

from grape-active_model_serializers.

Here is my base grape file

module Nsi
  class API < Grape::API
    format :json
    formatter :json, Grape::Formatter::ActiveModelSerializers

    mount Nsi::DictionaryResource
    mount Nsi::ParameterResource
    mount Nsi::DictionaryParameterResource

    add_swagger_documentation :format => :json,
                              :hide_documentation_path => true,
                              :mount_path => 'swagger_doc'
  end
end

same error without option

each_serialize: DictionarySerializer

from grape-active_model_serializers.

Looks like i have got anonymous class a = Class.new; a.name => nil in Grape::ActiveModelSerializers::SerializerResolver in instance initialization something like Grape::ActiveModelSerializers::SerializerResolver.new(Class.new, opts)

hm... I already have got it there...

module Grape
  module Formatter
    module ActiveModelSerializers
      class << self
        def call(resource, env)
          # !!!! resource.class.name => nil, resource.class => #<Class:0x005...>
          options = build_options(resource, env)
          serializer = fetch_serializer(resource, options)

          if serializer
            ::ActiveModelSerializers::Adapter.create(
              serializer, options
            ).to_json
          else
            Grape::Formatter::Json.call(resource, env)
          end
        end

        def build_options(resource, env)
          Grape::ActiveModelSerializers::OptionsBuilder.new(
            resource, env
          ).options
        end

        def fetch_serializer(resource, options)
          Grape::ActiveModelSerializers::SerializerResolver.new(
            resource, options
          ).serializer
        end
      end
    end
  end
end
