python - form.save() 之前的行没有保存正确的值

Question

我有一个模型形式的视图，ModelForm它并不真正包含模型中的所有字段。其他字段我使用了form.field = value之前的方法form.save()，但所有这些字段都保存为默认值。没有人接受我试图给予的价值。这是代码：

def PostAd(request):
    ad_post_form = AdPostForm()
    if request.user.is_authenticated:
        obj = Account.objects.get(user=request.user)
        if request.method == "POST":
            ad_post_form = AdPostForm(request.POST, request.FILES)
            if ad_post_form.is_valid():
                ad_post_form.created_by = request.user
                if obj.role == 'admin':
                    ad_post_form.is_active = True
                ad_post_form.save()
                return redirect('home')
        else:
            ad_post_form = AdPostForm(request.POST, request.FILES)
    else:
        if request.method == "POST":
            ad_post_form = AdPostForm(request.POST, request.FILES)
            if ad_post_form.is_valid():
                otp_number = random.randint(100000, 999999)
                ad_post_form.otp = otp_number
                ad_post_form.is_activated = False
                ad_post_form.save()
                current_id = ad_post_form.id
                current_contact_email = request.POST.get('contact_email')
                email_url_active = str(settings.URL_LOCAL) + 'new_ad/adidnumberis' + str(
                    current_id) + '/needactivate/activate/' + str(otp_number) + '/'
                email_msg = "Please Confirm adding the Ad to Jehlum. Click link " + email_url_active
                email = EmailMessage('Active Email', email_msg, to=[current_contact_email])
                email.send()
                return redirect('home')

            else:
                ad_post_form = AdPostForm()

    context = {
        'ad_post_form': ad_post_form,
    }

    return render(request, 'pages/post-ad.html', context)

问题是ad_post_form.is_active = True被保存为 False（默认）也ad_post_form.otp = otp_number被保存为 0（默认），我需要给出我在这里分配的特定值。

您需要获取模型实例并在那里设置属性。你可以通过使用 commit=False 调用 save 来做到这一点。

if ad_post_form.is_valid():
    ad_post = ad_post_form.save(commit=False)
    ad_post.created_by = request.user
    ...
    ad_post.save()
