factory-bot

问题 What is the purpose of transient do in FactoryBot factories? I've seen a lot of factories that begin with something like below. factory :car do owner nil other_attribute nil end ... I've found some information on this blog: http://blog.thefrontiergroup.com.au/2014/12/using-factorygirl-easily-create-complex-data-sets-rails/ But I still don't fully understand how and why to do this. My experience with FactoryBot is minimal. Could anyone with some experience using FactoryBot share some insight?

问题 Similar to the problem described here: http://rpheath.com/posts/411-how-to-use-factory-girl-with-rspec in Short (shorten'd code): spec_helper: config.use_transactional_fixtures = true config.use_instantiated_fixtures = false factories.rb: Factory.define :state do f.name "NY" end in my spec before(:each) do @static_model = Factory(:state) # with validate uniqueness of state name end error: duplicate entry name "NY" etc. Question: Shouldn't rspec clear database before each spec example and

问题 I have got a class, that is the base of some other classes that specializes the behavior: class Task < ActiveRecord::Base attr_accessible :type, :name, :command validates_presence_of :type, :name, :command # some methods I would like to test end The class CounterTask inherits from Task class CounterTask < Task end This all works fine until I am trying to test the base class, since it must have a type. FactoryGirl.define do factory :task do sequence(:name) { |n| "name_#{n}" } sequence(:command

问题 I have an ActiveRecord Model, PricePackage. That has a before_create call back. This call back uses a 3rd party API to make a remote connection. I am using factory girl and would like to stub out this api so that when new factories are built during testing the remote calls are not made. I am using Rspec for mocks and stubs. The problem i'm having is that the Rspec methods are not available within my factories.rb model: class PricePackage < ActiveRecord::Base has_many :users before_create

问题 In a Rails application, given three models User, Article and Reviewer with the following relationships and validations: class User < ActiveRecord::Base has_many :articles has_many :reviewers end class Reviewer < ActiveRecord::Base belongs_to :user belongs_to :article end class Article < ActiveRecord::Base belongs_to :user has_many :reviewers validate :has_reviewers? def has_reviewers? errors.add(:base, "article must have at least one reviewer.") if self.reviewers.blank? end end And the

问题 Suppose I have a model user , which has a uniqueness constraint on the email field If I call Factory(:user) once all is well, but if I call it a second time it'll fail with an "entry already exists" error. I'm currently using a simple helper to search for an existing entry in the DB before creating the factory...and calling any factory I make through that helper. It works, but it's not entirely elegant, and considering how common I assume this problem must be, I'm guessing there's a better

问题 I have the following models: class Ad < ActiveRecord::Base belongs_to :page has_one :image has_one :logo end class Page < ActiveRecord::Base has_many :logos has_many :images has_many :ads end class Image < ActiveRecord::Base belongs_to :page has_many :ads end And I have defined the following Factories: factory :page do url 'test.com' end factory :image do width 200 height 200 page end factory :ad do background 'rgb(255,0,0)' page image end When I try to do this: ad = FactoryGirl.create(:ad) I

问题 I am trying to get factory girl to run with rspec in my rails 4.1.1 app. Problem is when I run rspec in my command line, i get Failure/Error: verse = build(:verse) ArgumentError: Factory not registered: verse . I am at loss because I checked the factory girl getting started page and many answers here on SO andI still can't fix this issue. in my Gemfile: gem 'rails', '4.1.1' group :development, :test do gem 'rspec-rails' gem "factory_girl_rails" end my spec_helper.rb file: require 'factory

问题 I have been playing with Rails for a couple of years now and have produced a couple of passable apps that are in production. I've always avoided doing any testing though and I have decided to rectify that. I'm trying to write some tests for an app that I wrote for work that is already up and running but undergoing constant revision. I'm concerned that any changes will break things so I want to get some tests up and running. I've read the RSpec book, watched a few screencasts but am struggling
