我正在尝试运行不是由我的应用编写的应用。当我编写python manage.py makemigrations时，我得到：

Traceback (most recent call last):
      File "C:\Users\direwolf\AppData\Local\Programs\Python\Python36-32\lib\site-packages\django\db\backends\utils.py", line 64, in execute

    sqlite3.OperationalError: no such table: django_content_type

    The above exception was the direct cause of the following exception:

.操作错误：无此类表格：django内容类型
更新2：models.py中的产品类别

class Offer(TimeStampMixin, SEOFieldsMixin):
    title = models.CharField(u'Название предложения', max_length=255, blank=False)
    discription = models.TextField(u'Красивое описание оффера', null=False, blank=False)
    cover = models.ImageField(u'Обложка', blank=False, null=False)
    tags = TagAutocompleteField(blank=False, verbose_name='Теги')
    active = models.BooleanField(u'Активный?', default=True)
    publish = models.BooleanField(u'Показывать на сайте?', default=True)

    def preview_image(self):

        # except TypeError:

        get_latest_by = 'created_value'

    def __unicode__(self):
        return u'%s' % self.title

我没有找到管理类只有这个：

from django.contrib import admin

from app.motivity.models import TaskOffer, Offer, UserOffers

class TaskOfferAdmin(admin.TabularInline):
    model = TaskOffer
    exclude = ['meta_title', 'meta_description', 'meta_keywords']

class OfferAdmin(admin.ModelAdmin):
    list_display = ['preview_image','title','tags', 'publish']
    list_display_links = ['title']
    list_filter = ['tags']
    inlines = [TaskOfferAdmin, ]
    fields = ['title', 'discription', 'cover', 'tags']

class UserOfferAdmin(admin.ModelAdmin):
    pass

admin.site.register(UserOffers, UserOfferAdmin)
admin.site.register(Offer, OfferAdmin)

我在Mac OS 10.15.2上使用Python 3.6.5和Django == 2.1.7时遇到了同样的问题。我通过手动创建包含以下列的表django_content_type修复了这个问题：id, app_label, model
在运行python manage.py migrate时出现错误，应该在settings.py文件中的DATABASE键上指定的路径下创建了*.sqlite3文件。

    • 示例：**
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'base_site.sqlite3'),
    }
}

我的Squlite DB文件名是base_site.sqlite3，在项目的BASE_DIR中创建。

    • 应遵循的步骤：**
  • 使用以下命令连接到创建的SQLite DB：
sqlite3 <DB filename>
  • 使用以下命令创建表：
CREATE TABLE IF
NOT EXISTS "django_content_type" (
 "id" integer NOT NULL PRIMARY KEY AUTOINCREMENT,
 "app_label" varchar(100) NOT NULL,
 "model" varchar(100) NOT NULL
);
  • 最后，使用以下命令运行迁移：
python manage.py migrate --fake-initial

这应按预期运行迁移。

如果您的代码在导入时而不是运行时使用contenttypes数据库信息，则会出现此问题。例如，如果您添加了在模块级别或类级别运行的代码，如下所示：

TERM_CONTENT_TYPE = ContentType.objects.get_for_model(Term)

但您只是在运行创建该内容类型表的初始迁移 * 之后 * 才添加此错误，则下一个在新数据库上运行迁移的人将收到此错误。
在这种情况下，解决方案是将这样的代码移到只有在调用方法时才运行的地方，比如视图或其他方法。

只需删除您的db.sqlite3文件....并再次运行命令---〉py manage.py migrate然后，py manage.py makemigrations应用程序名称最后，py manage.py migrate...按照此过程希望您将修复您的prblm

对于测试数据库，简单修复可以是：

# Remove database and the history  cache for of applied migrations
rm db.sqlite3
find . | grep "__pycache__" | xargs sudo rm -rf

# Check that migration are not applied
python manage.py showmigrations

# Then apply fisrt only the admin module migrations
python manage.py migrate admin

# Then apply all others
python manage.py migrate

我认为这应该是一个很好的做法，总是应用管理迁移在第一次，然后其他人以后。
