我必须在接受嵌套属性的地方建模。我想构建一个测试以确保嵌套属性不能为空白等。我真的不明白如何进行测试。
我的两个简单模型:
# SeoMapping Model
class SeoMapping < ActiveRecord::Base
belongs_to :mappingtable, :polymorphic => true
attr_accessible :seo_url
validates :seo_url, :presence => true, :uniqueness => true
end
# Page Model
class Page < ActiveRecord::Base
has_one :seo_mappings, :as => :mappingtable, :dependent => :destroy
accepts_nested_attributes_for :seo_mappings
attr_accessible :content, :h1, :meta_description, :title, :seo_mappings_attributes
.........
end
这是我的 Page 和 Seo 工厂:
FactoryGirl.define do
factory :page do |f|
seo_mapping
f.title { Faker::Name.name }
f.h1 { Faker::Lorem.words(5) }
f.meta_description { Faker::Lorem.words(10) }
f.content { Faker::Lorem.words(30) }
end
end
FactoryGirl.define do
factory :seo_mapping do |f|
f.seo_url { Faker::Internet.domain_word }
end
end
我的测试:
require 'spec_helper'
describe Page do
it "has a valid factory" do
expect(create(:page)).to be_valid
end
# Cant get this spec to work?
it "it is invalid without a seo_url" do
page = build(:page)
seo_mapping = build(:seo_mapping, seo_url: nil)
page.seo_mapping.should_not be_valid
# expect(build(:page, :seo_mapping_attributes[:seo_url] => nil)).to_not be_valid
end
it "is invalid without a title" do
expect(build(:page, title: nil)).to_not be_valid
end
...............
end
