工厂女孩 - 如何创建记录层次结构?

Question

尝试为嵌套区域记录创建工厂。我为此目的使用祖先宝石。区域是 Place 的关联实体

地方工厂：

factory :place, traits: [:pageable] do
...
association :region, factory: :nested_regions
end

地区工厂：

factory :region do
level 'area'
factory :nested_regions do  |r|
# create South Hampton region sequence
continent = FactoryGirl.create(:region, 
level: Region.levels[:continent], 
name: 'Europe ')
country = FactoryGirl.create(:region, 
level: Region.levels[:country],
name: 'United Kingdom', 
parent: continent)
state = FactoryGirl.create(:region, 
level: Region.levels[:state], 
name: 'England',
parent: country)
county = FactoryGirl.create(:region, 
level: Region.levels[:county], 
name: 'Hampshire', 
parent: state)
name 'Southampton'
parent county
end
end 

当我将调试放入：nested_regions工厂时，我看到这些区域层次结构已经创建，但在 Place 的before_validation钩子中Region.all只返回"南安普顿"区域。使用 FactoryGirl 实例化整个区域层次结构的正确方法是什么？

不要为此目的使用变量。为每个级别创建单独的工厂，并按如下方式使用它：

factory :region do
name 'Region'
factory :county
association :parent, factory: :region
level 'county'
end
factory :area
association :parent, factory: :county
level 'Area'
name 'area'      
end  
end
