如何解决有没有办法让用户在 Django 网站上发帖之前先付款？？

这是我的模型

from django.db import models
from django.contrib.auth.models import User
from django.conf import settings
from django.urls import reverse


class Escort(models.Model):
    name = models.CharField(max_length=40)
    author = models.ForeignKey(User,on_delete=models.CASCADE)
    bio = models.TextField()
    phone = models.CharField(max_length=14)
    ethnicity = models.CharField(max_length=20)
    orientation = models.CharField(max_length=20)
    location = models.CharField(max_length=40)
    area = models.TextField()
    skin_color = models.CharField(max_length=40)
    hair_color = models.CharField(max_length=40)
    services = models.CharField(max_length=255)
    paid = models.BooleanField(default=False)

    def __str__(self):
        return self.name + ''~'' + str(self.author)

    def get_absolute_url(self):
        return reverse(''escort-details'',args=(str(self.id)))

这些是我的观点

from django.shortcuts import render
from django.views.generic import ListView,DetailView,CreateView
from .models import Escort



#def home(request):
    #return render(request,''home.html'',{})


class HomeView(ListView):
    model = Escort
    template_name = ''home.html''

class EscortDetailView(DetailView):
    model = Escort
    template_name = ''escort_details.html''

class AddEscortView(CreateView):
    model = Escort
    template_name = ''add_escort.html''
    fields = ''__all__''

这些是我的网址

from django.urls import path
from . import views

from .views import HomeView,EscortDetailView,AddEscortView

urlpatterns = [
    #path('''',views.home,name="home"),path('''',HomeView.as_view(),path(''escort/<int:pk>'',EscortDetailView.as_view(),name="escort-details"),path(''postad/'',AddEscortView.as_view(),name="add-escort"),]

对于四个视图我也有四个模板

我主要做的是创建一个网站来宣传护送服务。我希望用户注册/登录并单击链接“PostAd”并重定向到带有护送表单的页面。在为护送（护送模型）填写所有信息后，用户将需要先付款，然后广告/帖子才会出现在主页上（护送的 ul 将在主页中使用 HTML 进行组织）。谁能从这里给我建议？

解决方法

template <typename T>class Callback{private:    std::vector<std::function <void (T)>> func;public:    virtual void operator += (std::function<void (T)> _func)    {        func.push_back(_func);    }};

Callback<int> Test;

Callback< <(int,int,int)> > Test;

template <typename... Ts>//                ^^^^^^ Parameter packclass Callback{private:    std::vector<std::function <void (Ts...)>> func;//                                   ^^^^^//                                   Parameter pack expansionpublic:    virtual void operator += (std::function<void (Ts...)> _func)//                                                ^^^^^//                             Parameter pack expansion                 {        func.push_back(_func);    }};
