無法訪問Django REST視圖

Question

我正在閱讀Django Rest Framework上的一些內容，但是發現很難實現。有一個名爲「highscores.html」的頁面，在加載時應該向RESTful服務發出GET請求。它返回該用戶的高分列表。下面相關的代碼給出：

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') 

個

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(); 

}）;

其實，我完全被整個話題弄糊塗了，並且無法理解如何在highscore.html文件的「highscores」視圖中呈現Response。當我用服務器運行這個時，我得到一個404 Not Found錯誤。顯然，「高分」視圖甚至沒有被訪問，因爲「INSIDE HIGH SCORES」行沒有顯示在服務器中。作爲教程，我遵循這篇文章，https://realpython.com/blog/python/django-rest-framework-quick-start/#drf-setup這似乎很簡單，但我不明白很多東西，如呈現輸出，其格式（如JSON）等。有人可以幫忙嗎？即使鏈接到一個易於理解的初學者文檔也是有用的。提前致謝！

) 

Answer 1

歐凱，你有這樣的URL規則url(r'^highscores/(?P<id>\d+)/'。

所以在你的Ajax調用，您的網址只是"/highscores/"，並且您使用GET參數發送id，所以你的最終網址看起來像"/highscores/?id=some_id"，這是錯誤的。你的網址應該是這樣的"/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，在你看來，你發送的HTML模板響應，它應該是JSON響應。只需刪除template_name參數。

return Response(serializer.data)
