Rails宝典八十一式：Rails2.0之Fixtures尝鲜

关键字: Rails 2.0 Fixtures

Rails 2.0中Fixtures简单多了,看个例子：

# products.yml
couch:
  name: Couch
  price: 399.99
  manufacturer: lazyboy
  categories: furniture
tv_stand:
  name: TV Stand
  price: 149.95
  manufacturer: highdeph
  categories: furniture, electronics

# manufacturers.yml
lazyboy:
  name: LazyBoy
highdeph:
  name: HighDeph

# categories.yml
furniture:
  name: Furniture
electronics:
  name: Electronics

可以看出：
1，不用再给每条记录指定id了，系统自动添加一个fixture name的integer hash值
2，不用再给created_xx和updated_xx指定值了，自动由Time.now填充
3，当引用其他记录的id时，我们只需指定fixture name即可，而不用指定外键id了
