我一直在尝试将日期字段制作成一个表单，以便在呈现时显示当前日期。但是我未能找到解决这个问题的适当方法。
请在下面找到代码。

现在，当表单呈现时，没有任何反应。我想要的是"创建日期"中的日期应设置为今天的日期。但是，用户可以保持原样，也可以选择他/她选择的日期。但要求是日期字段应预先填充当前日期。
请在下面找到网络表单的屏幕截图。
网络表单
保存当前使用 auto_now=True
class DateField(auto_now=False， auto_now_add=False， **options(¶ 一个日期，在 Python 中由 datetime.date 实例表示。有一些额外的可选参数：
DateField.auto_now¶ 每次保存对象时自动将字段设置为现在。对于"上次修改"时间戳很有用。请注意，始终使用当前日期;它不仅仅是您可以覆盖的默认值
要在表单中显示当前日期，请使用：
form = CreateManufacturerForm(initial={'createddate': datetime.now()})
因此，经过许多令人沮丧的时间，在朋友Houda的帮助下，我终于能够解决问题。这就是我所做的。
views.py
在代码的GET部分，我写了以下内容。
initial_data = {
'createddate' : date.today().strftime("%Y-%m-%d"),
}
form = CreateManufacturerForm(initial = initial_data)
模板.html文件
我更改了以下内容
<input type="date" id="createddate" name = "createddate" class="form-control" autofocus required="true" value = '{{ form.createddate.value }}'>
我不确定这是否是最好的解决方案。但至少我让它工作了。我相信这个问题与 HTML 的日期格式有关
input type = 'date'
它只允许"YYYY-mm-dd">
谢谢大家。
