Question

我正在使用Class Based Views来渲染我的模板。到目前为止，这是我的代码：

Views.py：

class CashFlowView(TemplateView):
    template_name = "visualization/cash_flow.html"

    def get_context_data(self, **kwargs):
        context = super(CashFlowView, self).get_context_data(**kwargs)
        return context

    def get(self, request, *args, **kwargs):
        context = self.get_context_data(**kwargs)
        return self.render_to_response(context)

    def render_to_response(self, context, **response_kwargs):
        response_kwargs.setdefault('content_type', self.content_type)
        return self.response_class(
            request=self.request,
            template=self.get_template_names(),
            context=context,
            using=self.template_engine,
            **response_kwargs
        )

urls.py：

from django.conf.urls import url
from django.contrib import admin
from .views import CashFlowView

urlpatterns = [
    url(r'cash-flow', CashFlowView, name='cashflowView')
]

正如您所看到的，我正在使用templateView，但我发现这是一个奇怪的初始化错误。有什么想法吗？：

Internal Server Error: /visualization/cash-flow
Traceback (most recent call last):
  File "/Users/andy/Documents/venv_analytics/lib/python3.4/site-packages/django/core/handlers/exception.py", line 41, in inner
    response = get_response(request)
  File "/Users/andy/Documents/venv_analytics/lib/python3.4/site-packages/django/core/handlers/base.py", line 187, in _get_response
    response = self.process_exception_by_middleware(e, request)

    response = wrapped_callback(request, *callback_args, **callback_kwargs)
TypeError: __init__() takes 1 positional argument but 2 were given

您需要使用其as_view方法传递 TemplateView ：

urlpatterns = [
    url(r'cash-flow', CashFlowView.as_view(), name='cashflowView')
]

TypeError：Init仅占用1个位置参数
