在/ django的TemplateDoesNotExist

Question

出错了

views.py：

def index(request):
        user = request.user
        return render(request, 'main_app/index.html',{'user': user})

试过这个：

'DIRS': [os.path.join(BASE_DIR, 'templates')],

但没有帮助

CMD：

Internal Server Error: /

    response = get_response(request)

    raise TemplateDoesNotExist(template_name, chain=chain)

文件结构：

Django 2.0

Settings.py

INSTALLED_APPS = [
# 'main_app.apps.MainAppConfig',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'main_app'

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

Answer 1

BASE_DIR是根目录 您需要一个名为

的个人应用程序的PROJECT_APP_PATH

class AudioField(serializers.FileField):
    def to_internal_value(self, data):
        if isinstance(data, basestring):
            data = re.sub(r"^data\:.+base64\,(.+)$", r"\1", data)

            # Try to base64 decode the data url.
            try:
                decoded = base64.b64decode(data)
            except TypeError:
                raise serializers.ValidationError(_('Not a valid file'))

            file_name, file_ext, mime_type = self.i_need_the_file_extension_mimetype(decoded)


            data = ContentFile(decoded, name=file_name)

            return super(AudioField, self).to_internal_value(data)

快乐编码

Answer 2

您应该将模板从main_app/templates移动到嵌套的子文件夹main_app/templates/main_app。

例如，在django tutorial

中对此进行了解释

Answer 3

def索引（请求）： 表格= RegisterationForm（） 上下文= { ” } 返回render（request，'index.html'，上下文）
