使用视图中的表单集更新3个表单

from django import forms
from django.forms import formset_factory

# 创建3个表单类
class Form1(forms.Form):
    field1 = forms.CharField()

class Form2(forms.Form):
    field2 = forms.CharField()

class Form3(forms.Form):
    field3 = forms.CharField()

# 创建表单集类
FormSet = formset_factory(Form1, Form2, Form3)

# 视图函数
def update_forms(request):
    if request.method == 'POST':
        formset = FormSet(request.POST)
        if formset.is_valid():
            formset.save()
            # 数据保存成功的处理逻辑
    else:
        formset = FormSet()
    
    return render(request, 'update_forms.html', {'formset': formset})

# 模板 update_forms.html
<form method="post">
    {% csrf_token %}
    {{ formset.management_form }}
    {% for form in formset %}
        {{ form }}
    {% endfor %}
    <input type="submit" value="提交">
</form>
