HttpResponseRedirect
---------------------
The first argument to the constructor is required – the path to redirect to. This can be a fully
qualified URL (e.g.'http://www.yahoo.com/search/')
or an absolute path with no domain (e.g. '/search/')。
参数既可以使用完整的url，也可以是绝对路径
return HttpResponseRedirect('/commons/invoice_return/index/?message=error') #跳转到index界面
---------------------
redirect
---------------------
return redirect(reverse('commons.views.invoice_return_index', args=[])) #跳转到index界面
redirect 类似HttpResponseRedirect的用法，也可以使用 字符串的url格式 /..inidex/？a=add
---------------------
render_to_response
HttpResponse("<p>数据添加成功！</p>")
render(request,"index.html")You called this URL via POST, but the URL doesn't end in a slash and you have APPEND_SLASH set
将from的action地址改为/结尾的就可以了 或者 修改settings:APPEND_SLASH=False
