Question

我正在他们网站上进行Django教程。当我输入python manage.py makemigrations polls时，django会以No changes detected in app 'polls'进行响应。如果我python manage.py makemigrations polls

也一样

我在'polls.apps.PollsConfig'的{{1}}中添加了mysite/settings.py（我也只尝试过INSTALLED_APPS）
我的'polls'不为空
polls/models.py已添加到path('polls/', include('polls.urls')),
我尝试删除迁移文件夹内容，* pycache ，*。pyc和db.sqlite3

我的错误在哪里？

PS：我在Stackoverflow上阅读了有关此主题的所有主题，尝试了所有方法，但没有任何效果

bahs $ ./manage.py makemigrations
No changes detected

也：来自settings.py：

bash $ ./manage.py makemigrations
No changes detected

polls / models.py


INSTALLED_APPS = [
    'polls', # also tried with 'polls.apps.PollsConfig'
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]

# polls/models.py
from django.db import models


class Question(models.Model):
    question_text = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')


class Choice(models.Model):
    question = models.ForeignKey(Question, on_delete=models.CASCADE)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(default=0)

然后运行python manage.py makemigrations民意调查

下一步：python manage.py migration --fake APPNAME零

Django迁移时在Django教程中说“未检测到更改”
