class UserInfo(models.Model):    name = models.CharField(max_length=32)    ut = models.ForeignKey('UserType', on_delete=models.CASCADE)

创建数据库

python manage.py makemigrationspython manage.py migrate

插入表数据

修改 views.py

def initial(request):    from app01 import models    if request.method == 'GET':        nid = request.GET.get('nid')        m = models.UserInfo.objects.filter(id=nid).first()        dic = {'username': m.name, 'user_type': m.ut_id}        obj = forms.InitialForm(dic)        return render(request, 'initial.html', {'obj': obj})

修改 forms.py

class InitialForm(DForms.Form):    username = fields.CharField()    user_type = fields.IntegerField(        widget=widgets.Select(choices=[])    )    def __init__(self, *args, **kwargs):        # 执行父类构造方法        super(InitialForm, self).__init__(*args, **kwargs)        self.fields['user_type'].widget.choices = models.UserType.objects.all().values_list('id', 'caption')

在 templates 文件夹下创建 initial.html

    
            {
   { obj.username }}    {
   { obj.user_type }}

访问 ，根据 nid=2 参数初始化
