Question

我为移动应用程序制作了一个简单的python3 django服务器。但是在views.py中，我在测试时遇到了错误。

这是功能之一。

from django.shortcuts import render
from django.http import HttpResponse
from django.http import JsonResponse
from bns_info.models import Character, Dungeon, Tactics, Team
import json
import hashlib
import time

def login(request):
    if request.method == 'POST':
        data = request.body.decode("utf-8")
        receivedData = json.loads(data)

        receivedName = receivedData['characterName']
        character = Character.objects.get(name=receivedName)
        team = Team.objects.filter(teamNum=character['teamNum'])
        teamDungeonType = Dungeon.objects.filter(dType=team['dType'])

        retValue = {character['teamNum']:teamDungeonType['dType']}
        return JsonResponse(retValue, safe=False)

    else:
        return HttpResponse('Request is not POST method.')

这是我的模型设计。

class Character(models.Model):
    name = models.TextField(blank=True, null=True)
    teamNum = models.IntegerField(db_column='teamNum', blank=True, null=True)  # Field name made lowercase.
    id = models.IntegerField(blank=True, primary_key=True)

    class Meta:
        db_table = 'Character'

我收到的错误很少，这就是消息。

Internal Server Error: /login/ Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/django/core/handlers/exception.py", line 41, in inner response = get_response(request) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/django/core/handlers/base.py", line 187, in _get_response response = self.process_exception_by_middleware(e, request) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/django/core/handlers/base.py", line 185, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/Users/Dalek_Sec/BnS_Info/Server/appServer/bns_info/views.py", line 18, in login character = Character.objects.filter(name=receivedName) NameError: name 'Character' is not defined [04/Jun/2017 21:11:54] "POST /login/ HTTP/1.1" 500 60733

我认为这足以让我定义＆＃39;字符＆＃39;在模型中但django说Character没有定义。问题是什么???

像这样编辑您的视图，

def login(request): 
    if request.method == 'POST': 
        data = request.body.decode("utf-8")
        receivedData = json.loads(data)
        receivedName = receivedData['characterName'] 
        character = Character.objects.get(name=receivedName) 
        team = Team.objects.get(teamNum=character.teamNum) 
        teamDungeonType = Dungeon.objects.get(dType=team.dType) 
        retValue = {character.teamNum : teamDungeonType.dType} 
        return JsonResponse(retValue, safe=False) 
    else: 
        return HttpResponse('Request is not POST method.')

Django - 名称视图调用模型对象时出错
