Question

it "renders index page" do
  projects_user = FactoryGirl.create(:projects_user)
  get :index, id: projects_user.id
  expect(response).to render_template :index
end

这是我的控制器测试，当我运行它时说：验证失败：国家不能为空

我是stackoverflow和ruby soo的新手，我得到的任何帮助都很棒

FilesController：

class FilesController < ApplicationController
  before_filter :authenticate_user!

  def index
    @pu = ProjectsUser.find(params[:id])
    debugger
    @files = UserFile.includes(:user).where(project_id: @pu.id)
  end

  def new
    @file = UserFile.new
  end

  def create
    @file = UserFile.new(file_params)
    if @file.save
      flash[:success] = "File successfully uploaded!"
      redirect_to files_path
    else
      @files = UserFile.includes(:user).where(user_id: current_user.id)
      render :index
    end
  end

  def destroy
    @file = UserFile.find(params[:file_id])
    if @file.destroy
      flash[:success] = "File successfully deleted!"
      redirect_to files_path
    else
      flash[:error] = "File could not be deleted."
      redirect_to files_path
    end
  end

  protected

  def file_params
    params.require(:user_file).permit(:file, :user_id, :created_at, :updated_at, :project_id)
  end
end

国家控制员：

class CountriesController < ApplicationController
  def states
    @states = State.where(country_id: params[:id]).all
    return render :json => {success: true, status: 200, data: @states}
  end
end

国家模式：

class Country < ActiveRecord::Base
  validates :name, presence: true
  has_many :states
  has_many :users
  has_and_belongs_to_many :projects

  validates :name, presence: true
end

国家工厂：

require 'ffaker'

FactoryGirl.define do 
  factory :country do
    name {FFaker::AddressUS.country}
  end
end

输出错误：

Answer 1

问题出在

之内

  projects_user = FactoryGirl.create(:projects_user)

创建代码（您定义此工厂的地方）未设置国家/地区，这就是您收到错误的原因。

Ruby on rails，验证失败：国家不能为空
