无法访问Django REST视图

Question

我正在阅读Django Rest Framework上的一些内容，但是发现很难实现。有一个名为“highscores.html”的页面，在加载时应该向RESTful服务发出GET请求。它返回该用户的高分列表。下面相关的代码给出：

views.py：

from gamestore.serializers import ScoreSerializer 
from rest_framework.decorators import api_view 
from rest_framework.response import Response 

..

# display high scores 
@api_view(['GET']) 
def highscores(request, id): 

     print("INSIDE HIGH SCORES") 
     userobj = request.user 
     gameobj = Games.objects.get(pk=id) 
     scoreobj = Scores.objects.filter(game=gameobj, player=userobj) 

     if request.method == 'GET': 
       #print(scoreobj[0].game) 
       serializer = ScoreSerializer(scoreobj) 
       return Response(serializer.data, template_name='gamestore/highscores.html') 

models.py：

from django.contrib.auth.models import User 
from django.db import models 

class Usertypes(models.Model): 
     user = models.OneToOneField(User) 
     usertype = models.TextField() 

     def __unicode__(self): 
       return self.user_name 

class Games(models.Model): 
     name = models.CharField(max_length=100,unique=True) 
     category = models.CharField(max_length=100) 
     url = models.URLField() 
     developer = models.ForeignKey(User) 
     price = models.FloatField() 

     def __unicode__(self): 
       return self.name 

class Scores(models.Model): 
     game = models.ForeignKey(Games) 
     player = models.ForeignKey(User) 
     registration_date = models.DateField(auto_now=False, auto_now_add=False) 
     gamestate = models.TextField(blank=True, null=True) 
     high_score_1 = models.PositiveIntegerField(default=0) 
     high_score_2 = models.PositiveIntegerField(default=0) 
     high_score_3 = models.PositiveIntegerField(default=0) 
     high_score_4 = models.PositiveIntegerField(default=0) 
     high_score_5 = models.PositiveIntegerField(default=0) 
     last_score = models.PositiveIntegerField(default=0) 


     def __unicode__(self): 
       return self.game 

serializers.py：

from rest_framework import serializers 
from gamestore.models import Scores 

    class ScoreSerializer(serializers.ModelSerializer): 

      class Meta: 
        model = Scores 
        fields = ('game', 'player', 'high_score_1', 'high_score_2', 'high_score_3', 'high_score_4', 'high_score_5') 

个

highscores.html：

$(document).ready(function(){ 
     var game = $(this); 
     var id = document.getElementById("gameid").value; 
     alert(id); 
     var csrftoken = getCookie('csrftoken'); 
     $.ajax({ 
      type : "GET", 
      url : "/highscores/", 
      data : {'id': id}, 
      dataType : "json", 
      success : function(data){ 
      console.log(data); 
     } 
     }); 
     event.preventDefault(); 

}）;

其实，我完全被整个话题弄糊涂了，并且无法理解如何在highscore.html文件的“highscores”视图中呈现Response。当我用服务器运行这个时，我得到一个404 Not Found错误。显然，“高分”视图甚至没有被访问，因为“INSIDE HIGH SCORES”行没有显示在服务器中。作为教程，我遵循这篇文章，https://realpython.com/blog/python/django-rest-framework-quick-start/#drf-setup这似乎很简单，但我不明白很多东西，如呈现输出，其格式（如JSON）等。有人可以帮忙吗？即使链接到一个易于理解的初学者文档也是有用的。提前致谢！

编辑：

urls.py：

from django.conf.urls import patterns, include, url 
from django.contrib import admin 
import gamestore.views 

urlpatterns = patterns('', 
     # Examples: 
     # url(r'^$', 'wsdProject.views.home', name='home'), 
     # url(r'^blog/', include('blog.urls')), 

     url(r'^admin/', include(admin.site.urls)), 
     url(r'^$','gamestore.views.home'),

     url(r'^highscores/(?P<id>\d+)/','gamestore.views.highscores'), 
     url(r'^gamestore/', include('gamestore.urls', namespace="gamestore")), 
     url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')) 
)

欧凯，你有这样的URL规则url(r'^highscores/(?P<id>\d+)/'。

所以在你的Ajax调用，您的网址只是"/highscores/"，并且您使用GET参数发送id，所以你的最终网址看起来像"/highscores/?id=some_id"，这是错误的。你的网址应该是这样的"/highscores/some_id"。你需要追加ID。 "/highscores/"+id

$(document).ready(function(){ 
           var game = $(this); 
           var id = document.getElementById("gameid").value; 
           alert(id); 
           var csrftoken = getCookie('csrftoken'); 
           $.ajax({ 
             type : "GET", 
             url : "/highscores/"+id, 

             dataType : "json", 
             success : function(data){ 
               console.log(data); 
             } 
           }); 
           event.preventDefault(); 
         }); 

而且，在你看来，你发送的HTML模板响应，它应该是JSON响应。只需删除template_name参数。

return Response(serializer.data)
