未定义的方法`permit＆＃39; for＆＃34; 1＆＃34;：String

Question

运行RSpec时出现此错误，我不知道它对我有什么要求？我不知道为什么说permit未定义？这1:string事发生了什么？如果有人有想法，我很乐意知道。为清楚起见，这是我的错误和代码。

CONTROLLER:

  class SubscribersController < ApplicationController
def index
  @subscriber = Subscriber.all
end

def new
  @subscriber = Subscriber.new
end

def create
  @subscriber = Subscriber.create(subscriber_params)
  if @subscriber.save
    flash[:notice] = "Subscriber Has Been Successfully Created"
    redirect_to new_subscriber_path(:subscriber)
  else
    render "new"
  end
end

def search
  @subscriber = Subscriber.new
end

def visit
  @subscriber = Subscriber.find_by_phone_number(params[:phone_number])
  if @subscriber
    @subscriber.visit += 1
    @subscriber.save
    flash[:notice] = "thanks"
    redirect_to subscribers_search_path(:subscriber)
  else
    render "search"
  end
end


private

def subscriber_params
 params.require(:subscriber).permit(:first_name, :last_name, :email, :phone_number)
end
end

TEST：

  require "rails_helper"

  describe SubscribersController do
  include Devise::TestHelpers

  let(:user) { FactoryGirl.create(:user)}


  it "creates a new subscriber" do
    sign_in(user)
    subscriber = FactoryGirl.create(:subscriber)
    expect { post :create, :subscriber =>  subscriber }.to    change(Subscriber, :count).by(1)
  end
end

SUBSCIRBER OBJECT

我认为这里的问题是，当您在规范中提交请求时，您提供的是ruby对象而不是值的哈希值。请尝试使用以下内容：

subscriber = FactoryGirl.attributes_for(:subscriber)
expect { post :create, :subscriber => subscriber }.to ...
