Django中的这个模板有什么问题？

Question

from django.shortcuts import render 
from django.http import HttpResponse   #http response sends back html/basic webpage 
from django.conf.urls import include 
from django.template import loader 
from .models import Album 

# Create your views here. 
'''def index(request): 
    all_objects = Album.objects.all() 
    html = '' 
    for album in all_objects: 
     url = "/music/" + str(album.id) + "/" 
     html += '<a href = "' + url + '">' + album.album_title + '</a><br>' 
    return HttpResponse(html) 
''' 
def index(request): 
    all_albums = Album.objects.all() 
    #template = loader.get_template('music/index.html') 
    context = {'all_albums': all_albums} 
    return render(request, 'music/index.html', context) 
    #return HttpResponse(template.render(context, request)) 

def detail(request, album_id): 
    return HttpResponse("<h2>Details of Album with id:" + str(album_id)+ "</h2>") 

产生完全正确的模板。 当我添加不存在的相册模板。 这是我添加了2个相册，并与我的数据库同步，当我冲浪到第三个模板页面时，我应该得到404错误。 而对于这个代码是 -

from django.http import Http404 
from django.shortcuts import render 
from django.http import HttpResponse 
from django.template import loader 
from .models import Album 


def index(request): 
    all_albums = Album.objects.all() 
    #template = loader.get_template('music/index.html') 
    context = {'all_albums': all_albums} 
    return render(request, 'music/index.html', context) 
    #return HttpResponse(template.render(context, request)) 
    #render has an inbuilt http return type 

def detail(request, album_id): 
    try: 
     album = Album.objects.get(pk=album_id) 
    except Album.DoesNotExist: 
     raise Http404("Album does not exist") 
    return render(request, 'music/detail.html', {'album':album}) 

当我进入http://127.0.0.1:8000/music/3/它产生一个404错误，我想做的事，但是当我在http://127.0.0.1:8000/music/2/键入它开始给错误是“在/音乐/ 2/TemplateDoesNotExist”。 这究竟是为什么？

Answer 1

的问题是，你的模板文件details.html应该是detail.html，detail后无s，如您views.py，它被提及作为music/detail.html。

或

你可以在你views.py更改为music/details.html。

模板名称应匹配。
