我正在学习如何在 Rails 中进行测试,并且正在为我的问题模型编写一个工厂:
require 'factory_bot'
FactoryBot.define do
factory :question do
sequence(:content) { |n| "question#{n}" }
source "BBC"
year "1999"
end
end

问题是我有一段has_many :choices关系,我的问题应该有 5 个选择。所以我想知道如何在工厂机器人上做到这一点。没有从文档中得到它,因此将不胜感激任何帮助。谢谢!
这是我的问题模型:
class Question < ApplicationRecord
belongs_to :question_status
belongs_to :user
has_many :choices
accepts_nested_attributes_for :choices, limit: 5
validates :content, :source, :year, presence: true
validate :check_number_of_choices,
def check_number_of_choices
if self.choices.size != 5
self.errors.add :choices, I18n.t("errors.messages.number_of_choices")
end
end
end

我选择的型号:
class Choice < ApplicationRecord
belongs_to :question
validates :content, presence: true, allow_blank: false
end

我的工厂代码:
FactoryBot.define do
factory :question_status do
name "Pending"
end
factory :choice do
sequence(:content) { |n| "choice #{n}" }
question
end
factory :question do
sequence(:content) { |n| "question #{n}" }
source "BBC"
year "1999"
user
question_status
before :create do |question|
create_list :choice, 5, question: question
end
end

我的功能测试(它仍然什么也不做,但由于我的验证,它已经无法创建问题):
require 'rails_helper'
RSpec.feature "Evaluating Questions" do
before do
puts "before"
@john = FactoryBot.create(:user)
login_as(@john, :scope => :user)
@questions = FactoryBot.create_list(:question, 5)
visit questions_path
end
scenario "A user evaluates a question correctly" do
puts "scenario"
end
end

select这里可能发生的情况是,与集合代理一起使用choices导致 Rails 在验证期间再次尝试从数据库加载集合,但它们尚未被持久化。select尝试从您的验证中删除
if self.choices.size != 5

无论如何,可能select实际上并不需要,因为Choice模型已经验证了内容必须存在。在构建列表时,您可能还需要将选项分配给问题
before :create do |question|
question.choices = build_list :choice, 5, question: question
end
