Python Django Form ｜ Group Model ｜ MultiSelect ｜使用MultiSelect小部件仅从表单中获取单个值

我试图从模板中获取用户的输入，我在Django Auth模型中的组模型中显示模板中的组列表，并期望多个值.

from django.contrib.auth.models import Group

class MyForm(forms.ModelForm):
    
    the_choices = forms.ModelMultipleChoiceField(queryset=Group.objects.all(),
                                                 required=False, 
                                                 widget=forms.CheckboxSelectMultiple)

    class Meta:
        model = Group
        exclude = ['name', 'permissions']

    
    def __init__(self, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)

views.py

from .forms import MyForm
from django.shortcuts import render
from django.views.generic import View

class see(View):

    def __init__(self):
        pass

    def get(self, request):
        context ={}
        context['form']= MyForm()
        return render(request, "home.html", context)
    
    def post(self, request):
        print(request.POST.get('the_choices'))

        return HttpResponse('Great!')

控制台中的输出

请参考图2，我希望控制台中有1和2(首选组名)，但它只返回2.
