url(r'^rentacar/list/$', extension_views.rentacar_list),

我正在使用模板作为模型并定义模板对象，然后从我的模板应用程序中获取它。是否有任何简便的方法来呈现我的模板。

异常位置：rentacar_list中的D：\ buggy \ extension \ views.py，第766行

模板模型

    class Meta():
        db_table = "template"

Answer 1

此错误即将到来，因为我正在导入我的客户模型模板并内置在模板中

from template.models import Template
from django.template import Context, Template
def func1(request):

  template = **Template**.objects.get(template_default__exact=1)

def func2(request):            
      template = **Template** ("""link{{ request.get_host }}{% url 'detail' driver_id=driver_id %}""")

相同的模板名称，但具有不同的导入。一个是内置导入，第二个是模型导入，这就是为什么发生属性错误的原因。

特别感谢：

这些伟人解决了这个答案。

Django类型对象'Template'没有属性'objects'？
