为什么我的函数返回的是对象标识而不是'ip'变量？

Question

在保存用户注册表单时，我希望保存用户的ip地址，但我的视图函数不会返回字符串。 我获取get\u client\u signup\u ip函数的对象标识：

<function get_client_signup_ip at 0x04461810>

表单.py：

    from django import forms
from captcha.fields import ReCaptchaField

from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm

from django.http import HttpRequest

from django.contrib.gis.geoip2 import GeoIP2

from . import views

from .models import CustomUser

class UserCreateForm(UserCreationForm):
    email = forms.EmailField(required=True)
    captcha = ReCaptchaField()

    class Meta:
        model = CustomUser # this makes the UserCreateForm always save data to the custom user model
        fields = ("username", "email", "password1", "password2")


    def save(self, commit=True, request=True): # user object (customuser) form is called to save with commit=true, so it gets teh ip and saves.
        user = super(UserCreateForm, self).save(commit=False)
        user.email = self.cleaned_data["email"]
        user.origin_ip = views.get_client_signup_ip(request)
        if commit:
            user.save()
        return user

视图.py

def get_client_signup_ip(request):
    g = GeoIP2()
    x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR')
    if x_forwarded_for:
        ip = x_forwarded_for
        ip2 = '192.227.139.106'
        city = g.city(ip2)
    else:
        ip = request.META.get('REMOTE_ADDR')
        ip2 = '192.227.139.106'
        city = g.city(ip2)

    return ip

网址.py

from django.urls import path

from . import views

urlpatterns = [
    path('signup/', views.SignUp.as_view(), name='signup'),
    path('signup/', views.get_client_ip, name='signup_ipaddress')

]

我希望在用户的origin\u ip字段中看到一个ip地址。相反，我得到了get\u client\u sign up函数的字符串表示形式。你知道吗

如何让视图函数get\u client\u sign\u ip返回字符串？你知道吗

Answer 1

要获取值，需要将其作为方法调用，而不是views.get_client_signup_ip。你知道吗

user.origin_ip = views.get_client_signup_ip(request)

另外，为了简单地从函数中获取ip，您不需要从方法中获得HttpResponse(ip)。你知道吗

def get_client_signup_ip(request):
    ..........

    return ip
