使用Django表单提交时出现错误

Question

I want to post data from 2 django forms but I can't save data to my db. Why is it? After I pushed submit button, I see message "it is required" below my price input box.

My views

def addproduct(request):

   user = request.user
   product_form = ProductForm(request.POST or None)
   product_image_form = ProductImageForm(request.POST or None)

   if product_form.is_valid() and product_image_form.is_valid():
      product = product_form.save(commit=False)
      product.user = request.user
      product.slug = slugify(product_form.cleaned_data['title'])
      product.featured = False
      product.active = False
      product.save()
      product_image = product_image_form.save(commit=False)
      product_image.featured = False
      product_image.save()
      return HttpResponseRedirect('/products/%s'%(product.slug))

My Models

class Product(models.Model):
   user = models.ForeignKey(settings.AUTH_USER_MODEL, blank=True, null=True)
   title = models.CharField(max_length=120)
   description = models.TextField(null=True, blank=True)
   price = models.DecimalField(decimal_places=0, max_digits=100, default=0)
   slug = models.SlugField(unique=True)

class ProductImage(models.Model):
   product = models.ForeignKey(Product)
   image = models.ImageField(upload_to='products/images/')
   featured = models.BooleanField(default=False)

My forms

from django import forms
from .models import Product, ProductImage

class ProductForm(forms.ModelForm):
   class Meta:
       model = Product
       fields = ('title', 'description', 'price')

class ProductImageForm(forms.ModelForm):
   class Meta:
       model = ProductImage
       fields = ('image', 'featured')

Answer 1

You get "This field is required" error not below the price input box but above image selector. You forget to pass request.FILES argument to the ProductImageForm :

product_image_form = ProductImageForm(request.POST or None,
                                      request.FILES or None)

And don't forget to specify enctype attribute in your <form> tag:

<form method="post" enctype="multipart/form-data">
