1、django2.0把from django.core.urlresolvers修改成了django.urls

报错如下：

File "D:\Envs\django-xadmin\lib\site-packages\xadmin-0.6.1-py3.6.egg\xadmin\models.py", line 8, in <module>

from django.core.urlresolvers import NoReverseMatch, reverse

ModuleNotFoundError: No module named 'django.core.urlresolvers'

解决方法：

修改D:\Envs\django-xadmin\lib\site-packages\xadmin-0.6.1-py3.6.egg\xadmin\models.py 文件

把from django.core.urlresolvers import NoReverseMatch, reverse 修改为：

1	`from django.urls import NoReverseMatch, reverse`

2、django2.0中需要给外键ForeignKey指定on_delete参数

报错如下：

File "D:\Envs\django-xadmin\lib\site-packages\xadmin-0.6.1-py3.6.egg\xadmin\models.py", line 45, in <module>

class Bookmark(models.Model):

File "D:\Envs\django-xadmin\lib\site-packages\xadmin-0.6.1-py3.6.egg\xadmin\models.py", line 49, in Bookmark

content_type = models.ForeignKey(ContentType)

TypeError: __init__() missing 1 required positional argument: 'on_delete'

解决方法：

把content_type = models.ForeignKey(ContentType)修改为：

1	`content_type = models.ForeignKey(ContentType,on_delete=models.CASCADE)`

3、 django2.0 forms表单初始化只需要一个参数

报错如下：

model = ModelChoiceField(label=_(u'Target Model'), widget=exwidgets.AdminSelectWidget)

File "D:\Envs\django-xadmin\lib\site-packages\xadmin-0.6.1-py3.6.egg\xadmin\views\dashboard.py", line 284, in __init__

forms.Field.__init__(self, required, widget, label, initial, help_text, *args, **kwargs)

TypeError: __init__() takes 1 positional argument but 6 were given

解决方法：

把forms.Field.__init__(self, required, widget, label, initial, help_text, *args, **kwargs) 修改成：

1	`forms.Field.__init__(self)`

4、导入QUERY_TERMS报错

报错如下：

File "D:\Envs\django-xadmin\lib\site-packages\xadmin-0.6.1-py3.6.egg\xadmin\plugins\filters.py", line 10, in <module>

from django.db.models.sql.query import LOOKUP_SEP, QUERY_TERMS

ImportError: cannot import name 'QUERY_TERMS'

解决方法：

把

from django.db.models.sql.query import LOOKUP_SEP, QUERY_TERMS

修改为：

1 2	`from django.db.models.sql.query import LOOKUP_SEP` `from django.db.models.sql.constants import QUERY_TERMS`

5、Settings缺少MIDDLEWARE_CLASSES属性，django2.0把MIDDLEWARE_ClASSES改成MIDDLEWARE

报错如下：

File "D:\Envs\django-xadmin\lib\site-packages\xadmin-0.6.1-py3.6.egg\xadmin\plugins\language.py", line 24, in <module>

if settings.LANGUAGES and 'django.middleware.locale.LocaleMiddleware' in settings.MIDDLEWARE_CLASSES:

File "D:\Envs\django-xadmin\lib\site-packages\django\conf\__init__.py", line 57, in __getattr__

val = getattr(self._wrapped, name)

AttributeError: 'Settings' object has no attribute 'MIDDLEWARE_CLASSES'

把

if settings.LANGUAGES and 'django.middleware.locale.LocaleMiddleware' in settings.MIDDLEWARE_ClASSES:

修改为：

1	`if settings.LANGUAGES and 'django.middleware.locale.LocaleMiddleware' in settings.MIDDLEWARE:`

6、 django-formtools导入失败，需要更新django-formtools

报错如下：

File "C:\Users\laoyan\Desktop\xadmin-django2\xadmin-django2\demo_app\..\xadmin\plugins\wizard.py", line 12, in <module>

from django.contrib.formtools.wizard.storage import get_storage

ModuleNotFoundError: No module named 'django.contrib.formtools'

卸载django-formtools

pip uninstall django-formtools

重新安装新版本的django-formtools

1	`pip install django-formtools==2.1`
