在基于类的视图中重写GET请求时，如何引用表单？

from django.views.generic.edit import FormView
from .forms import YourForm

class YourView(FormView):
    form_class = YourForm
    template_name = 'your_template.html'
    
    def get(self, request, *args, **kwargs):
        form = self.get_form()
        return self.render_to_response(self.get_context_data(form=form))
