这真是奇怪。如果我运行此代码(作为鼻子测试),它会打印“-0:34:00.0”,一切都很好
def test_o1(self):
observer = ephem.Observer()
observer.lon, observer.lat = math.radians(73.9), math.radians(40.7)
observer.horizon = '-0:34'
print observer.horizon
但是,如果我这样做:
def test_o2(self):
location = UserLocation()
location.foo()
其中UserLocation是:
# Document is mongoengine.Document
class UserLocation(Document):
[...]
def foo(self):
observer = ephem.Observer()
observer.lon, observer.lat = math.radians(73.9), math.radians(40.7)
observer.horizon = '-0:34'
我明白了:
Traceback (most recent call last):
File "/home/roy/deploy/current/python/local/lib/python2.7/site-packages/nose/case.py", line 197, in runTest
self.test(*self.arg)
File "/home/roy/deploy/current/code/pyza/models/test_user_location.py", line 82, in test_o2
location.foo()
File "/home/roy/deploy/current/code/pyza/models/user_location.py", line 134, in foo
observer.horizon = '-0:34'
TypeError: can only update value with String or number
知道可能会发生什么吗?
答案 0 :(得分:1)
Arrggghhh。我想到了。我的UserLocation源文件以:
开头来自将来导入unicode_literals
显然,_libastro坚持使用ascii字符串,而不是unicode。
