Rspec POST 导致未定义的方法“key?”对于:创建:符号

Rspec POST results in undefined method `key?' for :create:Symbol

在测试我的控制器时,我在 Rspec 中有一个规范,使用 factorygirl 作为数据;

describe 'POST #create' do
  context 'with valid attributes' do
    it 'saves the new child in the database' do
        expect{
          post '/children', :create, person: attributes_for(:child)
      }.to change(Person, :count).by(1)
    end

我收到一个错误

1) PeopleController POST #create with valid attributes saves the new child in the database Failure/Error: post '/children', :create, person: attributes_for(:child) NoMethodError: undefined method key?' for :create:Symbol # ./spec/controllers/people_controller_spec.rb:46:inblock (5 levels) in ' # ./spec/controllers/people_controller_spec.rb:45:in `block (4 levels) in '

我的控制器(这是无关紧要的一切,非常抱歉)

class PeopleController < ApplicationController
before_action :set_person, only: [:show, :edit, :update, :destroy]
before_action :set_type

def full_name
    [Person.christian_name, Person.surname].join ' '
end

def index
  @people = type_class.all
end

def new
    @person = type_class.new
end

def update
end

def show
end

def edit
end

def create
    if @person_type == 'Child'
    @person = Child.new(person_params)
    else
        @person = CareGiver.new(person_params)
    end
    if @person.save
        redirect_to @person
    else
        render 'new'
    end
end

def destroy
end

private

    def person_params
        if @person_type == 'Child'
            params.require(:child).permit(:type, :christian_name, :surname, :dob, :gender)
        else
            params.require(:care_giver).permit(:type, :christian_name, :surname, :email,
                                           :password, :password_confirmation)

        end

    end

    def set_type
        @person_type = type
    end

    def type
        Person.types.include?(params[:type]) ? params[:type] : "Person"
    end

    def people_types
        %w[Person Child Provider CareGiver]
    end

    def type_class
        type.constantize if type.in? people_types
    end

    def set_person
        @person = type_class.find(params[:id])
    end
end

这是将不同类型的人保存到一个 table (sti)。 似乎没有参数传递给控制器​​。当我此时使用调试器时,我可以创建一个 Child 对象,但 post 不会传递它。我添加了 '/children' 以获得正确的路线(尽管我读到 rspec 控制器测试绕过路线堆栈) 我盯着它看了好几个小时,我的胃里有一种你不知道为什么的感觉! 感谢您的帮助

  def set_type
    @person_type = type
end

def type
    Person.types.include?(params[:type]) ? params[:type] : "Person"
end

在我的控制器中找到此代码。 type 方法没有设置@person_type 可以使用的值。我摆脱了方法类型,并将 set_type 更改为

def set_type
        @person_type = params[:person][:type]
    end

不确定这是否安全?但现在测试通过了。 p.s。所有其他测试都失败了!!
