Fixture referencesでfixtureの外部キーをわかりやすく

Rails

Fixture referencesてのをさっき知ったが、これはナイスな予感。

参照先のページのは古くなってて、今は次のような使い方になってる。

<%
fixtures :employees
id = 0
%>

packaging:
  id: <%= id += 1 %>
  name: Packaging
  manager_id: <%= employees(:bob) %>
  
quality_assurance:
  id: <%= id += 1 %>
  name: Quality Assurance
  manager_id: <%= employees(:joe) %>
  
marketing:
  id: <%= id += 1 %>
  name: Marketing
  manager_id: <%= employees(:jane) %>

manager_idが何指してるかわかりやすくなった。

employees(:bob)はemployees.ymlのbobのidを返す。他のフィールドを返したければemployees(:bob, :name)。おおう。
