错误(1):Django2.1.1版本将django.core.urlresolvers改为了django.urls
异常信息:
ModuleNotFoundError: No module named 'django.core.urlresolvers'
解决方案:
修改site-packages\xadmin-0.6.1-py3.6.egg\xadmin\models.py 将 from django.core.urlresolvers import XXX 修改为 from django.urls import XXX
(2)django2.1.1中需要给外键指定on_delete参数
异常信息:
TypeError: __init__() missing 1 required positional argument: 'on_delete'
解决方案:
把ForeignKey模块 models.ForeignKey(User) 修改为 models.ForeignKey(User,on_delete=models.CASCADE)
(3)django2.1.1的 forms表单初始化只一个参数
异常信息:
TypeError: __init__() takes 1 positional argument but 6 were given
解决方案:
把 forms.Field.__init__(self, required, widget, label, initial, help_text, *args, **kwargs) 修改为 forms.Field.__init__(self)
(4)Settings缺少MIDDLEWARE_CLASSES属性,django2.1.1把MIDDLEWARE_ClASSES改成>MIDDLEWARE
异常信息:
AttributeError: 'Settings' object has no attribute 'MIDDLEWARE_CLASSES'
解决方案:
将xadmin\plugins\language.py 中的: if settings.LANGUAGES and 'django.middleware.locale.LocaleMiddleware' in settings.MIDDLEWARE_ClASSES: 改成: if settings.LANGUAGES and 'django.middleware.locale.LocaleMiddleware' in settings.MIDDLEWARE:
(5)django-formtools导入失败,更新django-formtools版本就好了

ModuleNotFoundError: No module named 'django.contrib.formtools'
解决方案:
pip uninstall django-formtools pip install django-formtools==2.1

另外,Django数据同步过程中遇到的问题:
1、错误信息
raise ImproperlyConfigured('mysqlclient 1.3.13 or newer is required; you have %s.' % Database.__version__) django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3.
解决办法:
C:\Python37\Lib\site-packages\django\db\backends\mysql(python安装目录)打开base.py,注释掉以下内容:
if version < (1, 3, 13): raise ImproperlyConfigured('mysqlclient 1.3.13 or newer is required; you have %s.' % Database.__version__)
2、错误信息:
File "C:\Python37\lib\site-packages\django\db\backends\mysql\operations.py", line 146, in last_executed_query
query = query.decode(errors='replace')
AttributeError: 'str' object has no attribute 'decode'
解决办法:打开此文件把146行的decode修改为encode
