如何将不同的模型作为额外的字段添加到ModelForm？

from django import forms
from .models import YourModel

class YourModelForm(forms.ModelForm):
    class Meta:
        model = YourModel
        fields = '__all__'

class YourModelForm(forms.ModelForm):
    extra_field = forms.CharField(max_length=100)

    class Meta:
        model = YourModel
        fields = '__all__'

from django.shortcuts import render, redirect
from .forms import YourModelForm

def your_view(request):
    if request.method == 'POST':
        form = YourModelForm(request.POST)
        if form.is_valid():
            # 处理表单数据
            form.save()
            return redirect('success')
    else:
        form = YourModelForm()
    
    return render(request, 'your_template.html', {'form': form})
