Question

我正在创建单元测试py文件（tests.py），然后我收到以下错误消息。你能否告诉我如何解决它。

pydev debugger: warning: psyco not available for speedups (the debugger will still work correctly, but a bit slower)

OK

对正确方向的任何指导表示赞赏。

UPDATES1 我添加了我的tests.py源代码

# -*- encoding:utf-8 -*-

from django.contrib.gis.geos import GEOSGeometry
from django.test.testcases import TestCase
from django.utils import simplejson as json
import unittest
import utils

class RSCapTestCase(TestCase):

    fixtures = [ 'rs.json' ]

    def test_001_normal(self):

        response = self.client.get('/service/rs/cap', {})
        cap = json.loads(response.content)

        self.assertEqual(response.status_code, 200)
        self.assertEqual(cap['version'], '1.0')
        self.assertEqual(len(cap['rs']), 3)
        self.assertEqual(cap['rs'][0], 'r1')
        self.assertEqual(cap['updateSequence'], '0001')

    def test_002_version(self):

        response = self.client.get('/service/rs/cap/1.0', {})
        cap = json.loads(response.content)

        self.assertEqual(response.status_code, 200)
        self.assertEqual(cap['version'], '1.0')
        self.assertEqual(len(cap['rs']), 3)
        self.assertEqual(cap['rs'][0], 'r1')
        self.assertEqual(cap['updateSequence'], '0001')

    def test_003_version_sequence(self):

        response = self.client.get('/service/rs/cap/1.0/0001', {})
        cap = json.loads(response.content)

        self.assertEqual(response.status_code, 200)
        self.assertEqual(cap['version'], '1.0')
        self.assertEqual(len(cap['rs']), 3)
        self.assertEqual(cap['rs'][0], 'r1')
        self.assertEqual(cap['updateSequence'], '0001')

UPDATES2 我添加了以下代码

_ _ init _ _.py（与tests.py相同的文件夹）

import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'py23.settings'

执行tests.py

时，这是控制台

Finding files... done.
Importing test modules ... done.

FAILED (errors=43)

Answer 1

以下是我在不对代码进行任何更改的情况下解决此问题的方法：

进入Eclipse中的项目属性
转到“PyDev - PYTHONPATH”然后转到“字符串替换变量”选项卡
点击“添加变量”
名称：“DJANGO_SETTINGS_MODULE”，值：设置模块的位置（如eros的答案中的“py23.settings”）

这至少对我有用。

Answer 2

我只需添加以下内容：

import os
from os.path import abspath, dirname
import sys

# Set up django
project_dir = abspath(dirname(dirname(__file__)))
sys.path.insert(0, project_dir)
os.environ['DJANGO_SETTINGS_MODULE'] = 'py23.settings'

python：GeoDjango：Eclipse：在单元测试期间，引发ImportError，“无法导入设置'％s'（是否在sys.path上？是否有语法错误？）
