Django项目中pytest配置失败运行报错，请求排查原因

项目结构 #

backend
  |-foodgram
        |-foodgram
        |-manage.py
  |-api
  |-users
  |-tests
  |-pytest.ini

错误信息 #

ERROR backend/tests/test_user.py - django.core.exceptions.ImproperlyConfigured: Requested setting REST_FRAMEWORK, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

当前pytest.ini配置 #

[pytest]
python_paths = foodgram/
DJANGO_SETTINGS_MODULE = foodgram.settings
norecursedirs = env/*
addopts = -vv -p no:cacheprovider
testpaths = tests/
python_files = test_*.py

修复方案 #

• 调整python_paths路径：你的foodgram.settings模块实际位于backend/foodgram/foodgram/目录下，原配置的python_paths = foodgram/仅指向外层foodgram目录，导致pytest无法找到内层的settings模块。修改后的配置如下：

[pytest]
python_paths = foodgram/foodgram/
DJANGO_SETTINGS_MODULE = foodgram.settings
norecursedirs = env/*
addopts = -vv -p no:cacheprovider
testpaths = tests/
python_files = test_*.py

• 快速验证方式：若不想修改配置文件，可在运行pytest时手动指定环境变量测试：

DJANGO_SETTINGS_MODULE=foodgram.settings pytest

如果此命令能正常执行，即可确认问题源于路径配置错误。

• 运行路径检查：确保在backend目录下执行pytest命令，因为pytest.ini存放于此，pytest会优先读取当前工作目录下的配置文件。
