模板未在Django中加载 [英] Templates not loading in Django

问题描述

问题:模板无法随视图一起加载....

Problem: template not loading with view ....

我一直在遵循django教程，希望能使我创建的一些模板正常工作.看起来像这样.

I've been following a django tutorial, hoping to get some templates working that I created. It looks like this.

app/templates
└── app
    └── profile.html

设置文件如下:

"""

本教程提到了定义模板目录，因此我定义了:

The tutorial mentioned defining a template dir so I defined:

TEMPLATE_DIRS = [os.path.join(BASE_DIR, 'templates')]

但是，这没有用，所以我还看到了模板节中的DIRs选项，我将其设置为与上面添加的TEMPLATE_DIRS相同的值.

However, that didn't work so I also saw the DIRs option in the template stanza to I set that to the same value as TEMPLATE_DIRS that I added above.

我仍然看不到这里的任何变化.我显然缺少关于配置的一些信息，这些信息应该指向模板，但是我对此感到困惑.

I still don't see any change here. I am obviously missing something about the config that should point to the template but I'm stumped as to what that is at the moment.

视图:

from django.shortcuts import render, HttpResponse
import requests
import json

# Create your views here.

def index(request):
    return HttpResponse('Hello World!')

def second_view(request):
    return HttpResponse('This is the second view!')

def profile(request):
    jsonList = []
    req = requests.get('https://api.github.com/users/<username_here>')
    jsonList.append(json.loads(req.content.decode()))
    parsedData = []
    userData = {}
    for data in jsonList:
        userData['name'] = data['name']
        userData['email'] = data['email']
        userData['public_gists'] = data['public_gists']
        userData['public_repos'] = data['public_repos']
        userData['avatar_url'] = data['avatar_url']
        userData['followers'] = data['followers']
        userData['following'] = data['following']
    parsedData.append(userData)
    return HttpResponse(parsedData)

localhost:8000/app/profile的页面源

The page source of localhost:8000/app/profile

{'followers': 1, 'public_repos': 5, 'avatar_url': 'https://avatars.githubusercontent.com/u/XXXXX', 'email': None, 'following': 4, 'name': None, 'public_gists': 1}

推荐答案

如果您的 templates 文件夹位于项目的根文件夹中，并且您具有这样的 profile.html : templates/app/profile.html ，那么您的视图应类似于:

If your templates folder is in your project root folder and you have profile.html like this: templates/app/profile.html then your view should be something like:

def some_view(request)
    # some code
    return render(request, 'app/profile.html')

您的个人资料视图可能是:

Your profile view could be:

def profile(request)
    # your code
    return render(request, 'app/profile.html', {'data': userData})

现在，在模板 profile.html 中，您可以访问对象 data

Now, in your template profile.html, you can access the object data
