from django import forms

class CalculatorForm(forms.Form):
    OPTIONS = (
        ('add', '加法'),
        ('subtract', '减法'),
        ('multiply', '乘法'),
        ('divide', '除法'),
    )
    operation = forms.MultipleChoiceField(choices=OPTIONS, widget=forms.SelectMultiple)

from django.shortcuts import render
from .forms import CalculatorForm

def calculator(request):
    if request.method == 'POST':
        form = CalculatorForm(request.POST)
        if form.is_valid():
            selected_options = form.cleaned_data['operation']
            # 处理用户选择的选项
            # ...
    else:
        form = CalculatorForm()
    
    return render(request, 'calculator.html', {'form': form})

<form method="post">
