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

**报错如下：**

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> <p>2</p> <p>3</p> </td> 
   <td> <p><code>&nbsp;&nbsp;</code><code>File&nbsp;"D:\Envs\django-xadmin\lib\site-packages\xadmin-0.6.1-py3.6.egg\xadmin\models.py",&nbsp;line&nbsp;8,&nbsp;in&nbsp;&lt;module&gt;</code></p> <p><code>&nbsp;&nbsp;&nbsp;&nbsp;</code><code>from&nbsp;django.core.urlresolvers&nbsp;import&nbsp;NoReverseMatch,&nbsp;reverse</code></p> <p><code>ModuleNotFoundError:&nbsp;No&nbsp;module&nbsp;named&nbsp;'django.core.urlresolvers'</code></p> </td> 
  </tr> 
 </tbody> 
</table>

**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：

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> </td> 
   <td> <p><code>from&nbsp;django.urls&nbsp;import&nbsp;NoReverseMatch,&nbsp;reverse</code></p> </td> 
  </tr> 
 </tbody> 
</table>

**2、django2.0中需要给外键ForeignKey指定on\_delete参数**

**报错如下：**

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> <p>2</p> <p>3</p> <p>4</p> <p>5</p> </td> 
   <td> <p><code>&nbsp;&nbsp;</code><code>File&nbsp;"D:\Envs\django-xadmin\lib\site-packages\xadmin-0.6.1-py3.6.egg\xadmin\models.py",&nbsp;line&nbsp;45,&nbsp;in&nbsp;&lt;module&gt;</code></p> <p><code>&nbsp;&nbsp;&nbsp;&nbsp;</code><code>class&nbsp;Bookmark(models.Model):</code></p> <p><code>&nbsp;&nbsp;</code><code>File&nbsp;"D:\Envs\django-xadmin\lib\site-packages\xadmin-0.6.1-py3.6.egg\xadmin\models.py",&nbsp;line&nbsp;49,&nbsp;in&nbsp;Bookmark</code></p> <p><code>&nbsp;&nbsp;&nbsp;&nbsp;</code><code>content_type&nbsp;=&nbsp;models.ForeignKey(ContentType)</code></p> <p><code>TypeError:&nbsp;__init__()&nbsp;missing&nbsp;1&nbsp;required&nbsp;positional&nbsp;argument:&nbsp;'on_delete'</code></p> </td> 
  </tr> 
 </tbody> 
</table>

**解决方法：**

把content\_type = models.ForeignKey(ContentType)修改为：

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> </td> 
   <td> <p><code>content_type&nbsp;=&nbsp;models.ForeignKey(ContentType,on_delete=models.CASCADE)</code></p> </td>

  </tr> 
 </tbody> 
</table>

**解决方法：**

把forms.Field.\_\_init\_\_(self, required, widget, label, initial, help\_text, \*args, \*\*kwargs) 修改成：

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> </td>

  <tr> 
   <td> <p>1</p> <p>2</p> </td> 
   <td> <p><code>from&nbsp;django.db.models.sql.query&nbsp;import&nbsp;LOOKUP_SEP</code></p> <p><code>from&nbsp;django.db.models.sql.constants&nbsp;import&nbsp;QUERY_TERMS</code></p> </td>
