django2.0集成xadmin0.6报错集锦

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
    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：

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
    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：

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：

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
    from django.db.models.sql.query import LOOKUP_SEP, QUERY_TERMS
ImportError: cannot import name 'QUERY_TERMS'

解决方法：

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

修改为：

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
    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：

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：
