如何在django CBV(基于类的视图)createviews中上传图片

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

from django.db import models

class MyModel(models.Model):
    image = models.ImageField(upload_to='images/')

from django.urls import path
from .views import MyModelCreateView

urlpatterns = [
    path('create/', MyModelCreateView.as_view(), name='mymodel_create'),
]

from django import forms
from .models import MyModel

class MyModelForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = ['image']

from django.views.generic.edit import CreateView
from .models import MyModel
from .forms import MyModelForm

class MyModelCreateView(CreateView):
    model = MyModel
    form_class = MyModelForm
    template_name = 'mymodel_create.html'
    success_url = '/success/'

    def form_valid(self, form):
        form.instance.user = self.request.user
        return super().form_valid(form)

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