如何抑制Django中的弃用警告？ [英] How to suppress the deprecation warnings in Django?

问题描述

每次我使用 django-admin 命令 - 即使在TAB完成 - 它会抛出一个 RemovedInDjango19Warning （如果我使用测试命令，还有更多）。我如何禁止这些警告？

我在Python 3.4（在虚拟环境中）使用Django 1.8。

据我所知，所有这些警告来自图书馆，而不是我的代码，这里有一些例子：

• ... / lib / python3.4 / importlib / _bootstrap.py：321：RemovedInDjango19警告：django.contrib.contenttypes.generic已被弃用，将在Django 1.9中删除。其内容已被移动到django.contrib.contenttypes的字段，表单和管理子模块。
return f（* args，** kwds）




• ... / lib / python3 .4 / site-packages / django / contrib / admin / util.py：7：RemovedInDjango19警告：django.contrib.admin.util模块已被重命名。改用django.contrib.admin.utils。
改用django.contrib.admin.utils，RemovedInDjango19Warning）




• ... / lib / python3.4 / site-packages / django / templatetags / future.py：25：RemovedInDjango19警告：从``future``库加载``url``标签已被弃用，将在Django 1.9中删除。改用默认的``url``标签。
RemovedInDjango19Warning）

解决方案

在查看我Django 1.8项目的其他依赖关系中的弃用警告时，使用

  python -Wd manage.py runserver 
  

，我可以通过暂时添加

过滤掉Django的弃用警告pre> 导入警告
从django.utils.deprecation import RemovedInDjango110警告
warnings.filterwarnings（action =ignore，category = RemovedInDjango110Warning）


到我的 settings.py （可能在任何加载的模块中启动）。我不知道如何将过滤器作为一个额外的 -W 选项，即

  python -Wd -Wi :: RemovedInDjango110警告manage.py runserver 
  

导致忽略无效的-W选项：未知警告类别：RemovedInDjango110警告。

Every time I'm using the django-admin command — even on TAB–completion — it throws a RemovedInDjango19Warning (and a lot more if I use the test command). How can I suppress those warnings?

I'm using Django 1.8 with Python 3.4 (in a virtual environment).

As far as I can tell, all those warnings come from libraries not from my code, here are some examples:

• …/lib/python3.4/importlib/_bootstrap.py:321: RemovedInDjango19Warning: django.contrib.contenttypes.generic is deprecated and will be removed in Django 1.9. Its contents have been moved to the fields, forms, and admin submodules of django.contrib.contenttypes. return f(*args, **kwds)

• …/lib/python3.4/site-packages/django/contrib/admin/util.py:7: RemovedInDjango19Warning: The django.contrib.admin.util module has been renamed. Use django.contrib.admin.utils instead. "Use django.contrib.admin.utils instead.", RemovedInDjango19Warning)

• …/lib/python3.4/site-packages/django/templatetags/future.py:25: RemovedInDjango19Warning: Loading the ``url`` tag from the ``future`` library is deprecated and will be removed in Django 1.9. Use the default ``url`` tag instead. RemovedInDjango19Warning)

解决方案

While reviewing deprecation warnings in other dependencies of my Django 1.8 project, using

python -Wd manage.py runserver

, I was able to filter out Django deprecation warnings by temporarily adding

import warnings
from django.utils.deprecation import RemovedInDjango110Warning
warnings.filterwarnings(action="ignore", category=RemovedInDjango110Warning)

to my settings.py (can presumably be in any module that's loaded at startup). I couldn't figure out how to include the filter as an extra -W option, i.e.

python -Wd -Wi::RemovedInDjango110Warning manage.py runserver

resulted in Invalid -W option ignored: unknown warning category: 'RemovedInDjango110Warning'.
