Python form.save（）前面的行未保存正确的值

我有一个模型表单视图，

ModelForm

实际上并不包含模型中的所有字段。在

form.save（）

之前，我使用了

form.field=value

方法的其他字段，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。代码如下：

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\u post\u表单。is\u active=True

保存为False（默认）

另外，

ad_post_form.otp=otp_number

被保存为0（默认值），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。您可以通过调用save with commit=False来实现这一点

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