昇腾开源生态专区

在嵌入式设备上部署一直没问题，而部署在Linux Centos7 上出现此问题，一般是因为版本问题导致。
解决方法 安装 pip3 install Django==1.11.1
然而又出现下面 ImportError: cannot import name patterns
vim touch/extra_apps/DjangoUeditor/urls.py

# coding:utf-8
from django import VERSION

if VERSION[0:2] > (1, 3):
from django.conf.urls import patterns, url
else:
from django.conf.urls.defaults import patterns, url

from .views import get_ueditor_controller

urlpatterns = [
url(r'^controller/$', get_ueditor_controller)
]

改为：

# coding:utf-8
from django import VERSION

if VERSION[0:2] > (1, 3):
from django.conf.urls import url
else:
from django.conf.urls.defaults import url

from .views import get_ueditor_controller

urlpatterns = [
url(r'^controller/$', get_ueditor_controller)
]

 

由于版本问题，顺而可能引起以下问题

render_to_string() got an unexpected keyword argument 'context_instance'

解决方法：

context must be a dict rather than RequestContext.
就是context变为
{
"context":context
}

由于版本升级，之前代码中

return render_to_response('info_count.html', {}, context_instance=RequestContext(request))

应该 改写为类似这种：

from django.shortcuts import render

return render(request, "info_main.html", {'time_refresh': time_refresh,
'time_refresh_long': time_refresh_long,
'time_refresh_net': time_refresh_net,
'version': version})
