Django:TemplateDoesNotExist(rest_framework/api.html)

Question

在我的视图函数中,我想返回一个json对象(data1)和一些text/html(form).这可能吗？

我的代码

@api_view(['POST'])
@permission_classes((AllowAny,))
def create_user(request):
    if request.is_ajax():
        if request.method == 'POST':
            serializer = SignupSerializer(data=request.data)
            print 'ser'
            print serializer
            if not serializer.is_valid():
                return Response(serializer.errors,\
                                status=status.HTTP_400_BAD_REQUEST)
            else:
                serializer.save()
                data={'status': 'Created','message': 'Verification email has been sent to your email. Please verify your account.'}
                return Response(data, template_name='register.html')
    else:
        return HttpResponse('hello world')

当我调用url时,我得到状态代码500,错误如下所示

TemplateDoesNotExist rest_framework/api.html

当我作为API检查时,我得到200 ok状态的响应.这表明我无法获取我的HTML页面

我应该如何根据要求获取我的HTML

提前致谢

Answer 1

确保你有rest_framework你的设置INSTALLED_APPS

Answer 2

This is my attempt to explain the problem and collect everyone else's responses into a single list. Thanks to everyone for giving me shoulders to stand on!

I believe this happens because Django REST Framework wants to render a template (rest_framework/api.html), but the template can't be found. It seems there are two approaches to fix this:

Approach 1: Make templates work

Ensure REST Framework is included in INSTALLED_APPS in settings.py:

INSTALLED_APPS = [
    ...
    'rest_framework',
    ...
]

And ensure APP_DIRS is True in your template configuration (it defaults to False if not specified). This allows Django to look for templates in installed applications. Here's a minimal configuration that seems to work, though you might have more config here:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'APP_DIRS': True,
    },
]

Approach 2: Return a JSON response

If you tell REST Framework to render a JSON response then it doesn't need to use a template so you don't need to change the APP_DIRS settings as mentioned above. It also seems like you might not even need to list rest_framework in INSTALLED_APPS, though it might be necessary to have it there for other reasons.

You can do this globally in settings.py:

REST_FRAMEWORK = {
    'DEFAULT_RENDERER_CLASSES': [
        'rest_framework.renderers.JSONRenderer',
    ]
}

Or if you're using the @api_view decorator then you can specify JSONRenderer on each view:

@api_view(['GET'])
@renderer_classes([JSONRenderer])
def some_view(request):
    return Response({'status': 'yay'})

See the REST Framework renderers documentation for details.

Answer 3

我也有同样的问题。确保在“已安装的应用程序”中的设置中安装了 rest_framework

Answer 4

确保您安装了pip install djangorestframeworkrest_framework并将其包含在setting.py中

INSTALLED_APPS = [
    'rest_framework',
]

Answer 5

''' 尝试其中之一肯定会对您有所帮助：

1：将rest_framework添加到settings.py应用程序列表中，有时您的应用程序列出的顺序可能是原因。'''

INSTALLED_APPS = [
    'rest_framework',
    ...
]

''' 2：检查您的模板设置。请参阅后端、DIR 和 APP_DIRS。如果您自定义了rest-framework模板，请检查您定义的路径是否正确，设置 APP_DIRS: True 。在大多数情况下，这将得到解决。'''

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [BASE_DIR, os.path.join(BASE_DIR, 'templates')],
        'APP_DIRS': True,
        ....
    }
]

''' 3：检查默认渲染器类设置：'''

REST_FRAMEWORK = {
    'DEFAULT_RENDERER_CLASSES': [
        'rest_framework.renderers.JSONRenderer',
        ...
    ]
}

''' 4：如果您在基于函数的视图上使用 api_view 装饰器，请确保您已正确提供渲染器。IE

@renderer_classes([JSONRenderer]) '''

Answer 6

确保您将以下内容添加到rest_framework您的文件中：installed_appssettings.py

INSTALLED_APPS = [
    'rest_framework',
]

Answer 7

我从旧的Django版本升级到Django 2.0时遇到了这个问题.我settings.py根本没有TEMPLATE指令,所以我从新的django-admin.py startproject ...运行中抓住了以下内容:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

settings.py如果您没有TEMPLATES指令,请将其添加到您的settings.py.为我工作.

Answer 8

我遇到了同样的问题，发现 rest_framework 没有添加到 settings.py 中已安装的应用程序中。添加它解决了我的问题。

Answer 9

setting.py如果没有添加rest_framework，则添加rest_framework

前任：

INSTALLED_APPS = ["rest_framework"]
