Django UnicodeDecode錯誤

Question

首先，我嘗試了所有可以在SO和Google上找到的方法，但都沒有成功，所以在這裏問。

我在學習django並正在做一個測試項目。一切都很順利，但創建superuser後，當我試圖登錄到管理面板，它顯示UnicodeDecodeError。我嘗試了幾種方法，但不斷收到錯誤。我在使用python 3的windows 7 32位上使用django 1.11。
我創建了一個應用程序students並註冊了該應用程序。然後跑到migrate。

學生/ 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 + ")" 

學生/ 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()), 
] 

有人可以幫助我解決這個問題？

這裏是traceback。

Answer 1

模型中的文件，並查看文件

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

from __future__ import unicode_literals 

的頂部添加這些太行，設置海峽方法相同：

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

，重試運行。

Answer 2

5月this幫助。

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

Answer 3

嘗試編碼爲utf-8。

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


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

但是，它似乎是一個特定環境問題。
