Question

我正在为表单使用基于类的视图，但图像不在db中上传，没有显示任何错误。这是我的models.py

class ProductCreateModel(models.Model):
    user            = models.ForeignKey('accounts.SellerProfileModel',
                    related_name='product_seller',
                    on_delete=models.CASCADE,editable=False)
    title           = models.CharField(max_length=120)
    slug            = models/.SlugField(max_length=255,unique=True,blank=True)
    description     = models.TextField(max_length=250)
    orignal_price   = models.DecimalField(decimal_places=2, max_digits=8)
    discount        = models.DecimalField(decimal_places=2,max_digits=4)
    discount_price  = models.DecimalField(decimal_places=2,max_digits=8)
    image1           = models.ImageField(upload_to=upload_image_path,blank=True,null=True)

这是我的forms.py

from django import forms
from .models import ProductCreateModel
class ProductCreateForm(forms.ModelForm):
    class Meta:
        model = ProductCreateModel
       fields = '__all__'

这是我的views.py

class ProductCreateView(views.LoginRequiredMixin,ActiveSellerOnlyMixin,generic.CreateView,):
template_name = 'products/create_new_product.html'
model = ProductCreateModel
form_class = ProductCreateForm
success_url = reverse_lazy('home')
def form_valid(self, form):

    product = form.save(commit=False)
    user =  get_current_user(self.request)
    image1 = form.cleaned_data['image1']
    form.instance.user = request.user
    return super(ProductCreateView, self).form_valid(form)
    # product.save()

现在表单已成功提交，但图片为空。

Answer 1

 <form class="firstform" method="POST"> {% csrf_token %} {% bootstrap_form form %} <input type="submit" class="btn btn default" value="Submit"> </form>

到

 <form class="firstform"  enctype="multipart/form-data" method="POST"> {% csrf_token %} {% bootstrap_form form %} <input type="submit" class="btn btn default" value="Submit"> </form>

在html中添加enctype="multipart/form-data"表单。

当您编写客户端代码时，当您的表单包含任何multipart/form-data元素时，您需要知道的只是<input type="file">。如果您想知道为什么会看到here。
