在 Django 中验证表单后如何更新模型的一个属性？

Question

我有模型

class Tutor(models.Model):
    name = models.CharField(max_length=100)
    qualification = models.CharField(max_length=100)
    experience = models.CharField(max_length=200)
    tution_fee = models.CharField(max_length=100)
    about = models.CharField(max_length=1000)
    demo_classes_link = models.CharField(max_length=1000)
    contact_number = models.CharField(max_length=10)
    email_id = models.EmailField(null=True, blank=True)
    material = models.CharField(max_length=1000)
    status = models.BooleanField(null=True, blank=True)

和一个表格

class GeeksForm(forms.ModelForm):
    # specify the name of model to use
    class Meta:
        model = Tutor
        fields = "__all__"

现在我已经使用 POST API 表单验证了所有数据。

def registration(request) :
    form = GeeksForm(request.POST)
    # Check if the form is valid:
    if form.is_valid():
        number = request.POST['contact_number']
        print(number)
        r = requests.get('http://apilayer.net/api/validate?access_key=***********&number=*******&country_code=+91&format=1', params=request.GET)
        if r.status_code == 200:
            form['status'] = 1 # I want to update this once is form is validated, django throws an error.
            form.save()
            return HttpResponse('Yay, it worked')
        currentID = form.auto_id
        print(currentID)
       # form = GeeksForm()
    else :
        print("Invalid")   
    return render(request, 'Tutorform.html', {'form': form})

表单验证成功后如何在 Django 中更新模型的状态参数？

Answer 1

将form['status'] = 1更改为form.cleaned_data['status'] = True

验证表单时，其数据也会被“清理”（即 consolidated into one uniform format），并存储在名为 cleaned_data 的字典中，该字典在保存表单时使用。你应该在那里编辑它。

不过，我不完全确定，BooleanField 可能需要 True 而不是 1。

也可以先保存实例，然后再编辑状态：

instance = form.save()
instance.status = True
instance.save()

Answer 2

检索基础模型实例，更改字段值并保存表单。

if r.status_code == 200:
    myform = form.save(commit=False) #returns model instance object
    myform.status = True
    myform.save()
    return HttpResponse('Yay, it worked')
