响应主体未被序列化

Question

我有一个 ActiveModel 序列化程序，可以将字段名称更改为 lowerCamelCase。但是当我尝试在 rspec

上测试它时，它在我的 response.body 上不起作用

ActiveModel::Serializer.setup do |config|
  config.key_format = :lower_camel
end

class DevelopmentAgentsSerializer < ActiveModel::Serializer
  attributes :id, :name, :email, :created_at, :updated_at, :phone
end

class DevelopmentAgentsController < ApplicationController
  def index
    @development_agents = DevelopmentAgent.all

    render json: @development_agents
   end
 end

it "returns a list of development agents" do
  get :index, format: :json

  expect(JSON.parse(response.body)).to eq(JSON.parse({development_agents: serialized_development_agent}.to_json))  
end

预期：{"development_agents"=>[{"id"=>3, "name"=>"Some name", "email"=>nil, "createdAt"=>"2019-08-06T17:30:47.372-03:00", "updatedAt"=>"2019-08-06T17:30:47.372-03:00", "phone"=>"(21)999999999"}]}

得到： {"development_agents"=>[{"id"=>3, "name"=>"Some name", "email"=>nil, "created_at"=>"2019-08-06T17:30:47.372-03:00", "updated_at"=>"2019-08-06T17:30:47.372-03:00", "phone"=>"(21)999999999"}]}

按照惯例，序列化程序的名称是单数的，即 DevelopmentAgentSerializer 而不是 DevelopmentAgentsSerializer（不要忘记也更改文件名）。如果不遵循此约定，将不会使用您定义的序列化程序，并且响应将只是 @development_agents.as_json

响应主体未被序列化
