如何使用一个提交按钮在django中提交多个易碎的表单？

from django import forms

class MainForm(forms.Form):
    field1 = forms.CharField()
    field2 = forms.CharField()
    field3 = forms.CharField()

from django.shortcuts import render

def my_view(request):
    if request.method == 'POST':
        main_form = MainForm(request.POST)
        if main_form.is_valid():
            # 执行提交操作
            pass
    else:
        main_form = MainForm()

    return render(request, 'my_template.html', {'main_form': main_form})

<form method="post">
  {% csrf_token %}
  {{ main_form.field1 }}
  {{ main_form.field2 }}
  {{ main_form.field3 }}
  <input type="submit" value="提交">
</form>
