花了接近一上午的时间,终于解决了。

但是数据库只存在django内置的几张表,其他的app里面的model表没有新建,查了很多答案,但是都没有成功,总结如下:
1.可能是app名没有注册到setting.py的install_app中
2.执行迁移命令时加上app名称,python manage.py migrations appname

"""
最终把这个问题翻译成英文,在*上搜到了答案:
数据model是我在公司通过数据库反向生成的,所以在class Meta 类中会有字段managed=False, 官方文档对这个字段的解释是"If False, no database table creation or deletion operations will be performed for this model.",之前建立视图也是将这个字段改为False,
所以在迁移到另一个数据库的时候不会生成表,于是将managed设置为True就完美解决了这个问题。
