如何在Django中处理上传的图片？

from django.db import models

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

from django import forms

class MyForm(forms.Form):
    image = forms.ImageField()

from django.shortcuts import render
from .forms import MyForm

def upload_image(request):
    if request.method == 'POST':
        form = MyForm(request.POST, request.FILES)
        if form.is_valid():
            image = form.cleaned_data['image']
            my_model = MyModel(image=image)
            my_model.save()
            return render(request, 'success.html')
    else:
        form = MyForm()
    return render(request, 'upload.html', {'form': form})

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