未正确读取FIXTURE_DIRS，安装了0个对象来自0个fixture

Question

这是我的设置

FIXTURE_DIRS = (
      os.path.join(BASE_DIR, "fixtures",)
)

$ python manage.py diffsettings | grep fixtures
FIXTURE_DIRS = '/home/user/project/src/fixtures'

奇怪的是，当我运行syncdb的时候，出现了以下情况。它会递归地加载在FIXTURE_DIRS中设置的每一个字符的路径。可是它找不到任何目录，因为这些目录根本就不存在。

$ python manage.py syncdb -v3

Answer 1

这个问题解决了，但我仔细检查了一下我的设置。

FIXTURE_DIRS = (
      os.path.join(BASE_DIR, "fixtures",)
)

应该是这样的：

FIXTURE_DIRS = (
      os.path.join(BASE_DIR, "fixtures",),
)

如果你看不出有什么不同，我在花了几个小时试图弄明白的时候也看不出来。唯一的区别就是一个 ,。看看 os.path.join(BASE_DIR, "fixtures",) 的末尾，现在多了一个 ,。

我预计将来会有其他人遇到这个问题。 所以我提供了这个答案。
