Question

一直在努力写出正确的测试，但我无法弄清楚。

评论属于用户和插座每个插座都有一个用户每个人都有很多评论每个用户都有很多网点

目前我收到此错误：

Failure/Error: let(:outlet) { FactoryGirl.build(:outlet) }

     ActiveRecord::RecordInvalid:
       Validation failed: Username has already been taken, Email has already been taken

我真的不知道还有什么可以尝试。我试过转换我的工厂和测试一堆，但只有不同的错误。任何帮助将不胜感激

工厂：

FactoryGirl.define do
  factory :comment do
    body "This is a comment"
    user
    outlet
  end

  factory :invalid_comment, class: Comment do
    body "This is a comment"
    user nil
    outlet nil
  end  
end

FactoryGirl.define do
  factory :outlet do
    category "vent"
    title "MyString"
    body "MyText"
    urgency 1
    user
  end

  factory :invalid_outlet, class: Outlet do
    category "qualm"
    title ""
    body ""
    urgency 3
    user factory: :user
  end
end

FactoryGirl.define do
    factory :user do
        sequence(:username) { |n| "test_user#{n}" }
        sequence(:email)    { |n| "test_user#{n}@email.com" }
        password "password"
    end

    factory :invalid_user, class: User do
        username ""
        email ""
        password ""
    end
end

测试

describe 'create' do
        context 'with valid attributes' do
            let(:outlet) { FactoryGirl.create(:outlet) }            
            let(:comment_params) { FactoryGirl.attributes_for(:comment) }
            let(:create) { post :create, params: { id: outlet , comment: comment_params } }

            it "creates new comment" do
                puts outlet
                puts comment_params
                expect { create }.to change { Comment.count }.by 1
            end
        end
    end

class CommentsController < ApplicationController

    def new
        @comment = Comment.new
    end

    def create
        @outlet = Outlet.find(params[:id])
        @comment = @outlet.comments.build(comment_params)

        if @comment.save
            redirect_to(@outlet)
        end
    end


    private
    def comment_params
        params.require(:comment).permit(:body, :outlet_id, :user_id)
    end
end

错误表明您生成的用户名/电子邮件与数据库中的名称冲突。如果您在以后的运行中仍然在数据库中创建了一次运行的用户名，则可能会发生这种情况。

如果您还没有使用它，请考虑将DatabaseCleaner gem添加到您的项目中。它提供了各种方法来确保在运行之间重置数据库。

Rspec无法让控制器创建动作
