无法使用 nosegae 导入 django 包
我正在尝试开始使用 nosegae,但是我遇到了一个问题,即在使用 django 时,我似乎无法让它通过即使是最简单的情况。
当没有 --without-sandbox
标志运行时,以下两个测试都会失败
def test_import_django ():
import django
def test_import_django_http ():
import django.http
Traceback (most recent call last):
File "C:\Python27\lib\site-packages\nose-1.1.2-py2.7.egg\nose\case.py", line 1

v_appserver.py", line 2219, in FindPathHook
return self._imp.find_module(submodule, [path_entry])
但是,如果我确实使用 --without-sandbox
至少第一个测试通过了
myproj.tests.test_import_django ... ok
myproj.tests.test_import_django_http ... ERROR
======================================================================
ERROR: myproj.tests.test_import_django_http

AttributeError: 'str' object has no attribute 'find_module'
有人遇到过并知道吗我怎样才能克服这个问题?
编辑
看来问题是递归导入,
def test_import_pdb ():
import pdb
pdb.set_trace ()
堆栈跟踪的一部分是
File "C:\Python27\lib\pdb.py", line 72, in __init__
import readline
注意到django.http<的
__init__
中的导入
/code> 也是堆栈跟踪的一部分
I am trying to get started with using nosegae, however I run into the issue that I can't seem to get it to pass even the simplest of cases when using django.
when running without the --without-sandbox
flag both the following tests fail
def test_import_django ():
import django
def test_import_django_http ():
import django.http
Traceback (most recent call last):
File "C:\Python27\lib\site-packages\nose-1.1.2-py2.7.egg\nose\case.py", line 1

File "C:\Program Files (x86)\Google\google_appengine\google\appengine\tools\de

return func(self, *args, **kwargs)

search_path)

File "C:\Program Files (x86)\Google\google_appengine\google\appengine\tools\de

v_appserver.py", line 2219, in FindPathHook
return self._imp.find_module(submodule, [path_entry])
Howevere if I do use --without-sandbox
at least the first test passes
myproj.tests.test_import_django ... ok
myproj.tests.test_import_django_http ... ERROR
======================================================================
ERROR: myproj.tests.test_import_django_http

AttributeError: 'str' object has no attribute 'find_module'
Has anyone encountered and know how I can go about past this?
Edit
It seems that the issue is recursive imports
def test_import_pdb ():
import pdb
pdb.set_trace ()
part of the stack trace is
File "C:\Python27\lib\pdb.py", line 72, in __init__
import readline
notice that an import
in __init__
of django.http
is also part of the stack trace

阅读 https://docs.djangoproject.com/en/dev/topics/testing/< /a> 关于 Django 测试。
据我所知,最好使用 django 附带的 unittest 或 doctest,因为它对 django 特定的测试有一些改进,例如表单字段输出测试和一些数据库功能。然而,这不是必需的,如果您想继续使用鼻子 - 认为您错过了 django 环境设置:
之外运行测试
这行代码需要在 ./manage.py --test UPD
是的,我之前的想法是错误的。所以我只是深入研究了鼻子和鼻子盖的来源,以及我的想法 - 检查鼻子版本中的 HardenedModulesHook 定义,因为在鼻子的躯干中我发现了以下内容:
这给出了以下内容 - 当 nosGAE 插件
begin()
方法被执行->调用 self._install_hook(dev_appserver.HardenedModulesHook) 来声明混合钩子类并创建它的实例,如 self.hook = Hook(sys.modules, self._path) 。 <- 有HardenedModulesHook.__init__
被调用,第二个参数为神秘的“_path”,但是在 NOSE 中,默认情况下这个参数应该是“imp”模块 ->这使得你有一个例外:所以我认为这可能是鼻子盖的问题:(
Read https://docs.djangoproject.com/en/dev/topics/testing/ about Django testing.
As I know it's better to use unittest or doctest shipped with django as it have several improvements for django-specific testing like form field output testing and some database features. Hovewer it's not essential and if you want to continue using nose - think you missed django environment setup:
This lines needed to run your tests outside of ./manage.py --test
UPD
Yeah my previous thought's were wrong. So I just digged into sources of nose and nose-gae, and what I think - check HardenedModulesHook definition in your nose version, cause in trunk of nose I've found following:
That gives following - when noseGAE plugin
begin()
method is executed -> thereself._install_hook(dev_appserver.HardenedModulesHook)
is called which declares mixed-hook class and creates it's instance likeself.hook = Hook(sys.modules, self._path)
. <- There isHardenedModulesHook.__init__
called with second argument as mystic '_path' however in NOSE this argument should be 'imp' module by default -> That makes an exception you've got:So I think it might be a problem with nose-gae :(
