必須先判斷is_valid(),才能獲取值.clean()

創建form對象時,從數據庫取值初始化:

    username = fields.CharField()
    user_type = fields.IntegerField(
        widget=widgets.Select(choices=[])
    )

    def __init__(self,*args, **kwargs):
        # 執行父類的構造方法
        super(InitialForm,self).__init__(*args, **kwargs)

        self.fields[
 
‘user_type‘].widget.choices = models.UserType.objects.all().values_list(‘id‘,‘caption‘)
