在 Django 中保存 ModelForm 后获取主键 [英] Get Primary Key after Saving a ModelForm in Django

问题描述

如何在保存 ModelForm 后获取主键?表单经过验证并保存后，我想将用户重定向到需要联系人主键的 contact_details 视图.

How do I get the primary key after saving a ModelForm? After the form has been validated and saved, I would like to redirect the user to the contact_details view which requires the primary key of the contact.

def contact_create(request):
    if request.method == 'POST':
        form = ContactForm(request.POST)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect(reverse(contact_details, args=(form.pk,)))
    else:
        form = ContactForm()

推荐答案

ModelForm 的保存 方法返回保存的对象.

The ModelForm's save method returns the saved object.

试试这个:

def contact_create(request):
    if request.method == 'POST':
        form = ContactForm(request.POST)
        if form.is_valid():
            new_contact = form.save()
            return HttpResponseRedirect(reverse(contact_details, args=(new_contact.pk,)))
    else:
        form = ContactForm()
