Django UnicodeDecode错误

标签: python django django-models

首先,我已经尝试了所有可以找到SO和google的方法,但没有一个工作,所以问这里。

我正在学习django并做一个测试项目。一切进展顺利但在我尝试登录管理面板后创建superuser时显示UnicodeDecodeError。我尝试了几种方法,但不断收到错误。我在使用python 3的32位Windows 7上使用django 1.11 我创建了一个应用students并注册了该应用。然后运行migrate

学生/ models.py

from django.db import models

class Students(models.Model):
    roll = models.IntegerField(primary_key=True)
    name = models.CharField(max_length=200)
    dept = models.CharField(max_length=200)
    inst = models.CharField(max_length=200)

    def __str__(self):
        return self.name + "("+ self.dept + ")"

学生/ views.py

from django.shortcuts import render
from django.views.generic.base import View
from students.models import Students

class StudentListView(View):
    def get(self,request):
        students = Students.objects.all()
        return render(request,'students/index.html',{'students':students})

urls.py

from django.conf.urls import url
from django.contrib import admin
from students.views import StudentListView

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^students/',StudentListView.as_view()),
]

有人可以帮我解决问题吗?

3 个答案:

答案 0 :(得分:1)

将这些行添加到模型文件的顶部并查看文件

# -*- encoding: utf-8 -*-

from __future__ import unicode_literals

也可以将 str 方法设置为:

def __str__(self):
   return "(%s)" % self.name

现在,再试一次。

答案 1 :(得分:0)

可以this帮助。

def __unicode__(self):
    return u"{} ({})".format(self.name, self.dept)

答案 2 :(得分:0)

尝试编码为utf-8。

# -*- encoding: utf-8 -*-
from __future__ import unicode_literals


def __unicode__(self):
    return u"{} ({})".format(self.name, self.dept)

但是,它似乎是一个特定于环境的问题。
