from django import forms

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

from django.shortcuts import render

def my_view(request):
    if request.method == 'POST':
        form = MyForm(request.POST, request.FILES)
        if form.is_valid():
            # 处理表单数据
            # ...
        else:
            # 表单验证失败，重新渲染表单页面，并将错误信息传递给模板
            return render(request, 'my_template.html', {'form': form})
    else:
        form = MyForm()
    
    return render(request, 'my_template.html', {'form': form})

<form method="post" enctype="multipart/form-data">
  {% csrf_token %}
  {{ form.as_p }}
  {% if form.errors %}
    <ul class="errorlist">
      {% for field in form %}
        {% for error in field.errors %}
          <li>{{ error }}</li>
        {% endfor %}
      {% endfor %}
    </ul>
