使用 django-environ 配置不当的 SECRET_KEY 错误

Question

在我的设置中，我使用 django-environ 来设置密钥：

import environ

env = environ.Env()    
SECRET_KEY = env.read_env('SECRET_KEY')  

在我的项目的根目录中，我确实有一个带有实际密钥的 .env 文件：

.env：

SECRET_KEY=qgw6s66n3e$27mmddfua*8yq6n%gz(!mx8e=@zbixk50-h020  

错误将在collectstatic. 这是回溯：

我错过了什么？

Answer 1

我认为你使用它是错误的。根据文档，您首先需要加载.env文件然后使用它。

尝试这个：

import environ
env = environ.Env()
environ.Env.read_env()
SECRET_KEY = env('SECRET_KEY')

还要确保该.env文件位于作为设置文件的目录中。或者，您可以将文件的位置显式传递给read_csv().
