我添加了一个新应用并创建了一些模型。我已经运行makemigrations并迁移，所有都成功了。但是，当我打开sqlite表时，没有创建任何表。
来自模特的样本：
from __future__ import unicode_literals
from django.db import models
from django.conf import settings

# Create your models here.
from service.models import ServiceContacts
class Subnets(models.Model):
subnet = models.GenericIPAddressField(protocol='IPv4',verbose_name="Subnet",blank=True,null=True)
subnet_mask = models.CharField(max_length=4,verbose_name="Subnet Mask",choices=settings.SUBNET_MASK_CHOICES,blank=True)
subnet_type = models.CharField(max_length=10 ,verbose_name='Subnet Type',choices=settings.SUBNET_TYPE_CHOICES,blank=True)
class Meta:

我应该在那里看到sites_subnets和sites_sitecontacts，以及其他很多。

尝试使用以下过程迁移特定应用。
如果您创建初始迁移，然后运行migrate命令，有时迁移不完全，请尝试使用以下命令进行迁移
python manage.py makemigrations
创建初始迁移，然后使用应用名称
运行migrate命令python manage.py migrate appname
希望这对你有帮助

好的，我做了什么。
python manage.py sqlmigrate sites 0001
这给了我迁移的sql，然后运行
sqlite3 db.sqlite3
打开数据库，然后我只是将sqlmigrate命令的输出复制并粘贴到sql中，现在全部正常工作
