django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APP
时间: 2024-04-13 14:13:27 浏览: 170
S is not configured. You either define the 'DJANGO_SETTINGS_MODULE' environment variable or call settings.configure() before accessing settings. Can you help me fix this error?

这个错误是由于没有正确配置 Django 的设置所导致的。在你的代码中,`from School.show.models import Testinfo` 尝试导入模型 `Testinfo`,但是在导入过程中出现了配置错误。
这个错误通常发生在没有正确设置 Django 的环境变量或调用 `settings.configure()` 方法之前访问设置时。在 Django 中,你需要设置环境变量 `DJANGO_SETTINGS_MODULE` 来指定你的项目的设置模块。
你可以尝试以下解决方案:
1. 确保你的 Django 项目的根目录下有一个名为 `manage.py` 的文件。你应该在该文件所在的目录下运行命令,而不是直接运行模型文件。
2. 检查你的环境变量是否正确设置了 `DJANGO_SETTINGS_MODULE`。你可以通过在命令行中运行 `echo %DJANGO_SETTINGS_MODULE%` 来检查它是否已设置。
3. 确保你在运行模型文件之前调用了 `django.setup()` 方法。这将设置 Django 的配置并加载应用程序。
```python
import django
django.setup()
# 然后才能导入模型
from School.show.models import Testinfo
```
请确保按照正确的方式运行你的 Django 项目,并且已经正确配置了环境变量和调用了必要的方法。如果问题仍然存在,请提供更多的代码和详细信息,以便我们能够更好地帮助你解决问题。

这个错误提示是因为在你的代码中调用了 Django 的模型但是没有正确配置 Django 的设置。你需要确保在使用 Django 模型前,正确配置了 Django 的设置,可以通过以下两种方式之一来实现:
1.设置环境变量 DJANGO_SETTINGS_MODULE,例如:
```
export DJANGO_SETTINGS_MODULE=myproject.settings
```
2.在代码中手动配置 Django 的设置,例如:
```
import os
import django
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings')
django.setup()
```
其中,myproject.settings 是你的 Django 项目的设置文件。
