在黄瓜中与factory_girl建立关联的最佳实践是什么?

发布于 2024-08-10 04:17:44 字数 514 浏览 2 评论 0原文

我通常使用此步骤来设置与factory_girl的记录:

Given /^the following (.+) records?:$/ do |factory, table|
  table.hashes.each do |hash|
    Factory(factory, hash)
  end
end

这是我在设置关联时的解决方法:

Given the following group record:
  | id | name |
  | 1  | foo  |
And the following item records:
  | name | group_id |
  | bar  | 1        |
  | baz  | 1        |
  # ...

我知道这很糟糕。从域人员的角度来看,使用 ids 会使整个事情变得脆弱和神秘。

所以,我的问题是——与factory_girl 建立关联以及像上面这样的表参数的最佳实践是什么?

I normally use this step to set up records with factory_girl:

Given /^the following (.+) records?:$/ do |factory, table|
  table.hashes.each do |hash|
    Factory(factory, hash)
  end
end

And here's my work-around when setting up associations:

Given the following group record:
  | id | name |
  | 1  | foo  |
And the following item records:
  | name | group_id |
  | bar  | 1        |
  | baz  | 1        |
  # ...

I know this is bad. Using ids makes the whole thing brittle and cryptic from the vantage of the domain person.

So, my question is -- what would be the best practice to set up an association with factory_girl and a table argument like the one above?

您可以在工厂中定义多个关联。
如下所示:

Factory.define :item do |item|
    item.name          "item_name"
end

Factory.define :group do |group|
    group.name          "group_name"
    group.items         { |items| [ items.association(:item), items.association(:item) ] }
end

执行 Factory(:group) 将创建包含两个项目的组 uplet。

You can define multiple associations in a factory.
Like the following :

Factory.define :item do |item|
    item.name          "item_name"
end

Factory.define :group do |group|
    group.name          "group_name"
    group.items         { |items| [ items.association(:item), items.association(:item) ] }
end

Doing a Factory(:group) will create your group uplet with two items in it.

您可以使用定义的 FactoryGirl Cucumber 步骤:
https://github.com/thoughtbot/factory_girl/blob/master /lib/factory_girl/step_definitions.rb

您只需一个 Cucumber 步骤即可设置您的项目和组:

Given the following items exists:
  | Name     | Group        |
  | Foo      | Name: Bar    |
  | Foam     | Name: Bar    |
  | Food     | Name: Bar    |

这样做时,组“Bar”的创建使用“find_or_create_by”功能,因此第一个调用创建组,接下来的 2 个调用找到已创建的组。

这样,所有 3 个项目将具有相同的组“Bar”,并且您可以根据需要创建任意数量的分组项目。

You can use the defined FactoryGirl Cucumber steps:
https://github.com/thoughtbot/factory_girl/blob/master/lib/factory_girl/step_definitions.rb

You can setup your items and your group(s) in just one Cucumber step:

Given the following items exists:
  | Name     | Group        |
  | Foo      | Name: Bar    |
  | Foam     | Name: Bar    |
  | Food     | Name: Bar    |

When doing it like this, the creation of group 'Bar' is using 'find_or_create_by' functionality, so the first call creates the group, the next 2 calls finds the already created group.

In this way all 3 items will have same group 'Bar', and you can create as many grouped items as you need.
