ActiveModelSerializers :camel_lower 配置不工作

Question

我想利用 AMS 创建 json 数据以在我的测试套件中作为 GraphQL 变量传递。显然，它支持 :camel_lower，它将像 :some_field 这样的散列键转换为 :someField，但我似乎无法让它工作。这是相关代码：

/config/initializers/active_model_serializers.rb:

ActiveModelSerializers.config.key_transform = :camel_lower

/app/serializers/service_serializer.rb:

class ServiceSerializer < ApplicationSerializer
  attributes :id, :name, :time_increment
end

rails 控制台：

ActiveModelSerializers.config.key_transform
 => :camel_lower 
s = Service.new(name: 'Test', time_increment: 10)
 => #<Service id: nil, name: "Test", time_increment: 10, created_at: nil, updated_at: nil> 
ss = ServiceSerializer.new(s)
 => #<ServiceSerializer:0x00007f3771dd9dc0 @object=#<Service id: nil, name: "Test", time_increment: 10, created_at: nil, updated_at: nil>, @instance_options={}, @root=nil, @scope=nil> 
ss.as_json
 => {:id=>nil, :name=>"Test", :time_increment=>10}

我期待的结果是：

 => {:id=>nil, :name=>"Test", :timeIncrement=>10}

Answer 1

ActiveModelSerializers 长时间处于某种维护状态，似乎没有收到任何更新。

我个人的选择是 blueprinter gem or jsonapi-serializers。 blueprinter 更接近 AMS。

使用起来非常容易

# Gemfile
gem 'blueprinter'

和通常的

bundle install

创建序列化程序非常简单

# e.g. app/blueprinter/service_blueprint.rb
class ServiceBlueprint < Blueprinter::Base
  # identifier :id

  fields :id, :name, :time_increment
end

添加一个classLowerCamelTransformer

# e.g. app/blueprinter/lower_camel_transformer.rb
class LowerCamelTransformer < Blueprinter::Transformer
  def transform(hash, _object, _options)
    hash.transform_keys! { |key| key.to_s.camelize(:lower).to_sym }
  end
end

并在 config/initializers/blueprinter.rb

Blueprinter.configure do |config|
  config.default_transformers = [LowerCamelTransformer]
end

测试一下

s = Service.find(1)
puts ServiceBlueprint.render(s)
# Will give you a nice output with lower camel case

Answer 2

使用

ActiveModelSerializers.config.adapter = :json 它对我有用

ActiveModelSerializers :camel_lower 配置不工作

ActiveModelSerializers :camel_lower configuration not working
