FactoryGirl 在创建新模型之前可以检查数据库中是否已存在模型吗？

我有以下工厂设置：

FactoryGirl.define do

  factory :country do |f|
    f.name "USA"
    f.country_code "USA"
    f.currency_code "USD"
  end

  factory :region do |f|
    f.name "East Coast"
    f.country {Country.first}
  end

  factory :state do |f|
    f.name 'CA'
    f.region {Region.first}
    f.country {Country.first}
  end 

end

我想在该地区做什么？状态工厂将检查国家/地区数据库中是否已存在条目，如果是，则使用该条目，并且仅当未找到条目时才创建新模型。

这是我想到的一个示例，但不确定如何创建它：

factory :state do |f|
  f.name 'CA'
  f.region {Region.first || Factory(:region}
  f.country {Country.first || Factory(:state}
end

我想要这样做的原因是将条目注入到我的数据库中，该数据库将填充表单选择字段和字段。这样我就可以用黄瓜进行测试。

I have the following factory setup:

FactoryGirl.define do

  factory :country do |f|
    f.name "USA"
    f.country_code "USA"
    f.currency_code "USD"
  end

  factory :region do |f|
    f.name "East Coast"
    f.country {Country.first}
  end

  factory :state do |f|
    f.name 'CA'
    f.region {Region.first}
    f.country {Country.first}
  end 

end

What I want to do in the region & state factories is to check if an entry already exists in the database for Country, if yes then use that and only if no entries are found should it create a new model.

Here is an example of what I have in mind, but not sure how to create this:

factory :state do |f|
  f.name 'CA'
  f.region {Region.first || Factory(:region}
  f.country {Country.first || Factory(:state}
end

The reason why I want to do this is to inject entries into my database which will populate form select fields & so that I can test using cucumber.

您可以使用回调来完成此操作：

FactoryGirl.define do

  factory :country do |f|
    f.name          "USA"
    f.country_code  "USA"
    f.currency_code "USD"
  end

  factory :region do |f|
    f.name "East Coast"
    after_build {|r| r.country = (Country.first || Factory(:country))}
  end

  factory :state do |f|
    f.name 'CA'
    after_build do |s|
      s.region  = Region.first  || Factory(:region)
      s.country = Country.first || Factory(:country)
    end
  end 

end

You could use callbacks to accomplish this:

FactoryGirl.define do

  factory :country do |f|
    f.name          "USA"
    f.country_code  "USA"
    f.currency_code "USD"
  end

  factory :region do |f|
    f.name "East Coast"
    after_build {|r| r.country = (Country.first || Factory(:country))}
  end

  factory :state do |f|
    f.name 'CA'
    after_build do |s|
      s.region  = Region.first  || Factory(:region)
      s.country = Country.first || Factory(:country)
    end
  end 

end
