如何使用django表单和模板更新图像输入

# forms.py
from django import forms

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

# views.py
from django.shortcuts import render
from .forms import ImageForm

def update_image(request):
    if request.method == 'POST':
        form = ImageForm(request.POST, request.FILES)
        if form.is_valid():
            image = form.cleaned_data['image']
            # 处理图像保存逻辑
            # 可以使用Django的文件处理功能保存图像文件
    else:
        form = ImageForm()
    
    return render(request, 'update_image.html', {'form': form})

# update_image.html
<form method="post" enctype="multipart/form-data">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">更新图像</button>
</form>
<img src="{{ image_url }}" alt="当前图像">

# urls.py
from django.urls import path
from .views import update_image

urlpatterns = [
    path('update_image/', update_image, name='update_image'),
]
