如何在django表单中填充当前用户

from django import forms
from django.contrib.auth.models import User

class MyForm(forms.ModelForm):
    class Meta:
        model = MyModel  # 替换为你自己的模型类
        fields = ['field1', 'field2']  # 替换为你自己的字段列表

from django.shortcuts import render

def my_view(request):
    form = MyForm(request.POST or None)
    if form.is_valid():
        instance = form.save(commit=False)
        instance.user = request.user
        instance.save()
        # 其他处理逻辑
    return render(request, 'my_template.html', {'form': form})
