Rspec格式将参数发布到String值

Question

当我发送一个对象json时,里面的所有字段都改为字符串,在控制器中断开我的验证,我得到以下错误.

Api::V1::BillsController POST #create when logged in 
     Failure/Error: post :create, { bill: bill_attributes }
     Apipie::ParamInvalid:
       Invalid parameter 'value' value "41.64794235693306": Must be Float
     # ./app/controllers/concerns/exception_aspects.rb:4:in exception_wrapper
     # ./spec/controllers/api/v1/bills_controller_spec.rb:135:in block (4 levels) in <top (required)>

我尝试的测试表明 request.headers['Content-Type'] = 'application/json'

let(:bill_attributes) { FactoryGirl.attributes_for :bill }

before(:each) do
   request.headers['Content-Type'] = 'application/json'
   post :create, { bill: bill_attributes }
end

it "when is valid description" do
    expect(json_response[:description]).to eq(bill_attributes[:description])
end

我的工厂是

FactoryGirl.define do
 factory :bill do
  description { FFaker::Lorem.phrase }
  value { (rand() * 100).to_f }
 end
end

我的控制器验证是

api :POST, "/bills", "Add a new bill to an event"
description "Add a new bill"
param :bill, Hash, :required => true, :action_aware => true do
    param :description, String, "Bill description"
    param :bill_photo, Hash, :required => false do
        param :base64image, String, "Base 64 image file"
    end
    param :value, Float, "Amount of the bill"
end

我试图改变验证:从价值Float到:number,但问题仍然存在

我正在使用rails 4.2.3和rspec 3.3.0

Answer 1

post :create, params: {}, as: :json

这适用于Rails 5.0.3和rspec-rails 3.6.0

Rails控制器规范现在继承自ActionDispatch :: IntegrationTest而不是ActionController :: TestCase.但是RSpec控制器规范仍然使用不推荐使用的ActionController :: TestCase. 相关的Rails在这里提交

我添加了 json 格式来发布请求，它的效果就像魅力一样

before(:each) do
   post :create, { bill: bill_attributes, format: :json }
end
