Question

我为自定义用户和视图编写了一个模型，允许我添加新用户，查看他们的个人资料信息以及登录/退出。但是，在为用户编写视图以更新其个人资料信息时，我发现正在显示的表单要求用户再次填写所有详细信息，即使他们不想更改该特定详细信息。例如，如果用户想要更改他们的姓氏，他们必须再次输入他们的电子邮件，密码，名字等。有没有办法让我自动填充此表单，用户可以只更改他们需要的内容？我已在下面附上我的表格和观点代码。非常感谢任何帮助！

views.py

@login_required(login_url='/login/')
def personal(request):
    """
    Personal data of the user profile
    """
    profile = MyUser.get_full_name #This returns the email address

    if request.method == "POST":
        form = ProfileForm(request.POST, instance=profile)
        if form.is_valid():
            form.save()
            messages.add_message(request, messages.INFO, _("Your profile information has been updated successfully."))

    else:
        form = ProfileForm

    template = "update_profile.html"
    data = { 'section': 'personal', 'form': form, }
    return render_to_response(template, data, context_instance=RequestContext(request))

forms.py

class ProfileForm(forms.ModelForm):
    """
    Profile Form. Composed by all the Profile model fields.
    """
    class Meta:
        model = MyUser
        exclude = ('is_active', 'is_admin', 'last_login')

你可以使用instance kwarg在GET上将当前的个人资料传递给你的表格（我看到你已经在POST上传递了它）。此外，在使用POST更改数据库后，请不要忘记执行HTTP重定向。像这样：

    form = ProfileForm(request.POST, instance=profile)
if request.method == 'POST:
    if form.is_valid():
        form.save()
        messages.add_message(request, messages.INFO, _("Your profile information has been updated successfully."))
        # TODO You need to do a redirect here
else:
        form = ProfileForm(instance=profile)
