Can't upload file in Django

Created UpdateView and can't update the model with the file upload using forms. Provided the code below. print(form.cleaned_data) returns file None in the traceback

models.py

`from django.db import models

# Create your models here.
class DashModel(models.Model):
    name = models.CharField(max_length=220)
    file = models.FileField(null=True, blank=True)`

forms.py

`from django import forms 
from .models import *

class AddModel(forms.ModelForm):

    class Meta:
        model = DashModel
        fields = ('name','file')

        widgets = {
            'name' : forms.TextInput(attrs={'class':'form-control'}),
            'file' : forms.FileInput,
        }`

views.py

`class DashModelUpdateView(UpdateView):
    template_name = 'dashboard/update_model.html'
    form_class = AddModel
    success_url = '/dashboard/search-models/'
    queryset = DashModel.objects.all()

    def form_valid(self,form):
        print(form.cleaned_data)
        form.save()
        return super().form_valid(form)`

Traceback

`[14/Apr/2021 01:00:00] "GET /dashboard/1/update/ HTTP/1.1" 200 16091
{'name': 'Some Name', 'file': None}`

Add enctype="multipart/form-data" to your form:

<form method="post" enctype="multipart/form-data">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Upload</button>
</form>

Note that request.FILES will only contain data if the request method was POST, at least one file field was actually posted, and the that posted the request has the attribute enctype="multipart/form-data". Otherwise, request.FILES will be empty.

Document.
