SECRET_KEY錯誤與環境變量

我正在通過the TaskBuster Django教程工作，其目標是幫助爲項目建立良好的開發設置過程。SECRET_KEY錯誤與環境變量

當我運行命令回聲$ SECRET_KEY

在任何我的「開發」環境或我的「測試」環境我得到的結果相同，所以我相信我的$ ENVIROMENTS /斌/ postactivate和predeativate變量正確設置。

我base.py文件夾包含

# Build paths inside the project like this: os.path.join(BASE_DIR, ...) 
import os 

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

def get_env_variable(var_name): 
    try: 
     return os.environ[var_name] 
    except KeyError: 
     error_msg = "Set the %s environment variable" % var_name 
     raise ImproperlyConfigured(error_msg) 

SECRET_KEY = get_env_variable('SECRET_KEY')

然而，當我嘗試運行我得到這個輸出的測試。

django.core.exceptions.ImproperlyConfigured: Set the SECRET_KEY environment variable

這使我相信，有一些問題與祕密密鑰，但我「米不清楚應該怎麼解決。

是os.environ [VAR_NAME]返回錯誤值的回報？如何看什麼正在恢復，所以我可以將它指向什麼，我寧願它返回？我是正確的道路上搞清楚了這一點？

這裏是我使用當前

測試文件

from selenium import webdriver 
from django.core.urlresolvers import reverse 
from django.contrib.staticfiles.testing import LiveServerTestCase 


class HomeNewVisitorTest(LiveServerTestCase): 

    def setUp(self): 
     self.browser = webdriver.Firefox() 
     self.browser.implicitly_wait(3) 

    def tearDown(self): 
     self.browser.quit() 

    def get_full_url(self, namespace): 
     return self.live_server_url + reverse(namespace) 

    def test_home_title(self): 
     self.browser.get(self.get_full_url("home")) 
     self.assertIn("TaskBuster", self.browser.title) 

    def test_h1_css(self): 
     self.browser.get(self.get_full_url("home")) 
     h1 = self.browser.find_element_by_tag_name("h1") 
     self.assertEqual(h1.value_of_css_property("color"), 
         "rgba(200, 50, 255, 1)")

您沒有名爲SECRET_KEY的環境變量。您需要在運行程序之前將其設置。

在Unix

export SECRET_KEY="password"

在Windows

set SECRET_KEY="password"

值得一提的是，當你關閉終端變量將消失。如果你想尋找他們，那麼有辦法。

感謝您的回答。我是否誤解了$ echo $ SECRET_KEY返回的命令？我認爲這是我postactivate文件中的祕密密鑰。 – aisflat439

不，'echo $ SECRET_KEY'事實上會返回環境變量。如果我沒有記錯的話，taskbuster教程會告訴你爲這些環境設置不同的Python環境和不同的設置文件。確保在測試環境中使用'export DJANGO_SETTINGS_MODULE =「taskbuster.settings.testing」設置環境變量DJANGO_SETTINGS_MODULE。你可能只需要在教程中稍微回溯一下。 – Andreas

我去檢查我的_test/bin/postactivate_文件，發現我犯的錯誤。安德烈亞斯和帕特里克都在正確的地方。我設置了SECRET_KEY變量，但忽略**導出**，所以我可以回顯它，但其他程序無法訪問它。謝謝你的幫助！這個問題很難解決，因爲我在_dev/bin/postactivate_中正確地完成了它。 – aisflat439
