如何将数据库查询集对象从基于类的视图(类SignUp(generic.CreateView))传递到Django中的模板

from django.views.generic import CreateView
from .models import SignUp
from django.shortcuts import render

class SignUpView(CreateView):
    model = SignUp
    template_name = 'signup.html'

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['signups'] = SignUp.objects.all()  # 获取SignUp模型的所有对象
        return context

{% for signup in signups %}
    <p>{{ signup.field_name }}</p>
{% endfor %}
