Writing and running tests. ImportError: No module named generic

Question

我是 tests in Django 的新手。我需要写一对。

Django 版本 1.9.7。 OS: Linux version 4.2.0-42-generic (buildd@lgw01-54) (gcc version 5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu2) ) #49-Ubuntu SMP Tue Jun 28 21:26:26 UTC 2016

我的简单测试代码是：

cat animal/tests.py

from django.test import TestCase
from animal.models import Animal 

class AnimalTestCase(TestCase):
    def say_hello(self):
        print('Hello, World!')

我是这样执行的./manage.py test animal

并出现以下错误：

Traceback (most recent call last):
  File "./manage.py", line 13, in <module>
    execute_from_command_line(sys.argv)
  File "/path-to-venv/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 353, in execute_from_command_line
    utility.execute()
  File "/path-to-venv/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 327, in execute
    django.setup()
  File "/path-to-venv/local/lib/python2.7/site-packages/django/__init__.py", line 18, in setup
    apps.populate(settings.INSTALLED_APPS)
  File "/path-to-venv/local/lib/python2.7/site-packages/django/apps/registry.py", line 85, in populate
    app_config = AppConfig.create(entry)
  File "/path-to-venv/local/lib/python2.7/site-packages/django/apps/config.py", line 90, in create
    module = import_module(entry)
  File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
  File "/path-to-venv/local/lib/python2.7/site-packages/autofixture/__init__.py", line 5, in <module>
    from autofixture.base import AutoFixture
  File "/path-to-venv/local/lib/python2.7/site-packages/autofixture/base.py", line 7, in <module> 
    from django.contrib.contenttypes.generic import GenericRelation
ImportError: No module named generic

我做错了什么？

Answer 1

您安装的 django-autofixture 版本不支持 Django 1.9，因为它的 GenericRelation.

导入已过时

尝试升级到最新版本。该项目的 changelist 表示在版本 0.11.0 中添加了 Django 1.9 支持。

为了让 Django 在您的 AnimalTestCase 中运行您的方法，您需要重命名它，使其以 test_:

开头

class AnimalTestCase(TestCase):
    def test_say_hello(self):
        print('Hello, World!')

Answer 2

你导入错误，正确的导入来自

django.contrib.contenttypes.fields import GenericRelation

但这似乎实际上来自 django auto-fixtures 而不是您自己的代码。好消息是您不需要自动夹具来进行这种简单的测试。就跟它说再见吧。
