在Django中以html格式将数据存储到数据库

Question

form.valid不起作用，当我使用html表单填写数据应存储在数据库中的表单以及如何上传图像，如何在html页面中定义表单时，我的代码中是否有任何错误，如下给出了我的models.py，views.py，forms.py，我搜索了很多论坛，但无法获得答案

models.py

class Deal(models.Model):
    Deal_Category = models.CharField(max_length=30, choices=(('F','Fashion'),
                                                    ('T', 'Travel') ))
    Deal_Title = models.CharField(max_length=30,blank=True)
    Deal_Redemption = models.CharField(max_length=50,blank=True)
    Deal_Start = models.DateField()
    Deal_End =models.DateField()
    Deal_Details = models.CharField(max_length=50,blank =True)
    Deal_Location= models.CharField(max_length=50,blank =True)
    Deal_Terms = models.CharField(max_length=50,blank =True)
    #Images = models.ImageField(upload_to='static/image',blank=True)

forms.py

class DealForm(forms.ModelForm):
    class Meta():
        model= Deal
        fields=('Deal_Category','Deal_Title','Deal_Redemption','Deal_Start','Deal_End','Deal_Details',
                'Deal_Location','Deal_Terms')

views.py

def deal_form(request):
    print("Deal")
    if request.method == 'POST':
        print("user")
        form = DealForm(data=request.POST )
        print("Deal1")
        if form.is_valid():
            print("Deal2")
            form.save(commit=True)
            print("Deal4")
        return render(request, 'advertizer/adver_create_coupon.html')
