Django项目TemplateDoesNotExist报错求助，模板路径配置异常

项目结构 #

├── manage.py
├── myProjet
│   ├── __init__.py
│   ├── settings.py
│   ├── templates
│   ├── urls.py
│   ├── wsgi.py
│   └── wsgi.pyc
├── app1
├── templates

当前settings.py配置 #

BASE_DIR =  os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'app1',
]


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

触发报错的视图函数 #

def SignupPage(request):
    if request.method=='POST':
        uname=request.POST.get('username')
        email=request.POST.get('email')
        pass1=request.POST.get('password1')
        pass2=request.POST.get('password2')

        if pass1!=pass2:
            return HttpResponse("Your password and confrom password are not Same!!")
        else:
            my_user=User.objects.create_user(uname,email,pass1)
            my_user.save()
            return redirect('login')
        
    return render (request,'signup.html')

错误信息 #

TemplateDoesNotExist at /

解决步骤 #

• 修正TEMPLATES中的DIRS路径配置：将'DIRS': [ os.path.join( 'templates')], 修改为 'DIRS': [os.path.join(BASE_DIR, 'templates')],。BASE_DIR代表manage.py所在的根目录，结合'templates'就能准确定位到根目录下的templates文件夹，而非子目录里的模板路径。
• 确认模板文件位置：确保signup.html文件存放在根目录的/templates文件夹内，路径对应为/templates/signup.html。
• 重启Django开发服务器：修改settings.py后，需要重启服务器让配置生效。

如果需要使用myProjet/templates目录下的模板（非当前需求），可将DIRS配置改为os.path.join(BASE_DIR, 'myProjet', 'templates')。
