Flask中，出现了递归的import错误
代码：
/Users/crifan/dev/dev_root/daryun/Projects/RunningFast/sourcecode/RunningFast-Server/runningfast/resources/Task.py
from User import location_fields, user_fields location_fields = { } user_fields = { } |
/Users/crifan/dev/dev_root/daryun/Projects/RunningFast/sourcecode/RunningFast-Server/runningfast/resources/User.py
from Task import task_fields bill_fields = { } task_fields = { } |
错误：
Traceback (most recent call last): File “db_manager.py”, line 4, in <module> from runningfast.app import db, app, gLog File “/root/RunningFast/staging/runningfast/app.py”, line 116, in <module> from runningfast.resources.RegisterLogin import * File “/root/RunningFast/staging/runningfast/resources/RegisterLogin.py”, line 16, in <module> from User import user_fields File “/root/RunningFast/staging/runningfast/resources/User.py”, line 14, in <module> from Task import task_fields File “/root/RunningFast/staging/runningfast/resources/Task.py”, line 15, in <module> from User import location_fields, user_fields ImportError: cannot import name location_fields |

【总结】
最后，去直接的把对应的模块内的全局变量定义，全部移动到一个文件内，然后上述两个文件都引用同一个文件，就可以解决递归import的问题了：
/Users/crifan/dev/dev_root/daryun/Projects/RunningFast/sourcecode/RunningFast-Server/runningfast/resources/User.py
from runningfast.models import * |
/Users/crifan/dev/dev_root/daryun/Projects/RunningFast/sourcecode/RunningFast-Server/runningfast/resources/Task.py
from runningfast.models import * |
/Users/crifan/dev/dev_root/daryun/Projects/RunningFast/sourcecode/RunningFast-Server/runningfast/models/__init__.py
bill_fields = { } task_fields = { } location_fields = { } user_fields = { } |
