Django : InlineFomsets with FileField, overwrite forms.ModelForm Function

I have a model Product and a model Document. The document has a foreign key to the product.

I want the user to upload multiple files in the same form for adding/editing Product.

I modified and example from net, it is working, but not with a FileField.

I know that I need to add request.File but until now I didn't added where is needed, because is not working.

models

class Product( models.Model):       #default attributes     name = models.CharField(max_length=200,db_index=True)     short_description = models.CharField(max_length=160)     description = models.TextField()    class Document(models.Model):        product = models.ForeignKey('products.Product', on_delete=models.CASCADE)      document = models.FileField(upload_to=upload_to)

forms

class DocumentModelForm(forms.ModelForm):     class Meta:         model = Document         fields = ['document']      DocumentInlineFormSet = forms.inlineformset_factory(     Product,     Document,     fields=('document', 'id'),     extra=0,     can_delete=False,     min_num=1, validate_min=True,  max_num=3, validate_max=True,

)

class ProductModelForm(forms.ModelForm):     class Meta:         model = Product         fields = [          'name',          'short_description',          'description',      ]    def __init__(self, *args, **kwargs):      super().__init__(*args, **kwargs)      self.checks = DocumentInlineFormSet(          instance=self.instance, prefix='checks',          data=self.data if self.is_bound else None)    def is_valid(self, commit=True):      product_valid = super().is_valid()      checks_valid = self.checks.is_valid()      return product_valid and checks_valid    def save(self,commit=True):      product = super().save(commit=commit)      product._checks = self.checks.save(commit=commit)      return product

template

<form method="POST" action="" enctype="multipart/form-data">      {% csrf_token %}      {{ form}}      {{ form.checks.management_form }}          {{ form.checks }}         <input type="submit" class="button" value="Submit">   </form>
