Django Createview外键字段的默认值

Django Createview外键字段的默认值

由于您是在URL中存储学校的子d，因此最好不要在表格中添加“学校”字段。然后，您可以使用以下

form_valid

方法设置学校：

from django.shortcuts import get_object_or_404class StudentCreateView(CreateView):    fields = ("name","age",)  # don't include 'school' here    ...    def form_valid(self, form):        school = get_object_or_404(School, slug=self.kwargs['school'])        form.instance.school = school        return super(StudentCreateView, self).form_valid(form)
