Question

我知道这个问题已被多次询问，但我找不到解决问题的任何解决方案。基本上，我在Django的类视图中有一个方法，该方法调用另一个方法，该方法引发AttributeError：'WSGIRequest' object has no attribute 'send_email'。

这是代码：

class PartyListView(ListView):
    # ...
    # ...

    def approve_party(self, party_id):
        returnObj = {}

        # get the party by id
        party = party_repo.get_party_by_id(party_id)
        if party is None:
            returnObj['message'] = "The requested party doesn't exist."
            jsonObj = json.dumps(returnObj)
            return HttpResponse(jsonObj, status=404, content_type="application/json")

        # change the status to Approved
        party.party_status = Core.PartyStatus.Approved
        party.save()

        # email the party team on the approval
        self.send_email(True, party)

        # return a json success response
        returnObj['message'] = "The party has been approved."
        jsonObj = json.dumps(returnObj)
        return HttpResponse(jsonObj, status=200, content_type="application/json")

    def send_email(self, isApprovalEmail, party):
        username = self.request.user.username
        from_email = username + "@example.com"
        recipient_list = [party.host.student_email]
        cc = ['admin@example.com']

        if isApprovalEmail:
            subject = "APPROVED Party Registration for {}".format(party.party_time)
            body = "approval email"

            email = EmailMessage(subject, body, from_email, recipient_list, cc=cc)
            email.send()
        else:
            subject = "REJECTED Party Registration for {}".format(party.party_time)
            body = "rejection email"

            email = EmailMessage(subject, body, from_email, recipient_list, cc=cc)
            email.send()

    # ...
    # ...

我尝试了以下事项：

重新排列方法send_email的顺序：位于approve_party上方，位于顶部，位于底部。
在不复制任何内容的情况下，在另一个编辑器中重写整个文件。
使用PyCharm将缩进转换为空格选项以确保缩进良好。
在课堂上写下其他虚拟函数，并尝试从approve_party调用它们 - 它们都不起作用。

这里是完整的追溯：

approve_party已在urls.py中注册，如下所示：

urlpatterns = [
    # ...,
    url(r'^parties/approve/([0-9]*$)', views.PartyListView.approve_party, name="Approve Party"),
    # ...
]

您正在错误地使用基于类的视图。基于类的视图应使用as_view方法注册。

url(r'^parties/approve/([0-9]*$)', views.PartyListView.as_view(), name="Approve Party"),

但是，在这种情况下，看起来更简单的是使approve_party和send_email常规函数而不是您的视图方法。

def approve_party(request, party_id):
    returnObj = {}
    ...
    send_email(request, True, party)

    return HttpResponse(jsonObj, status=200, content_type="application/json")

def send_email(request, isApprovalEmail, party):
    username = request.user.username

然后将您的网址格式更改为：

url(r'^parties/approve/([0-9]+$)', views.approve_party, name="approve-party"),

我建议使用[0-9]+代替[0-9]*来确保网址至少包含一个数字，我会避免在网址模式名称中使用空格。
