'DateField'对象没有属性'value_from_datadict'

Question

我一直在到处研究这个问题的答案，但我只是想在我的models.py上创建的DateField中添加一个小部件，在那里您可以看到实际的日历，就好像您直接通过输入类型=date的html来做一样。由于我有几个日期字段，这就成了一个问题，因为它们都需要与表单和小部件的其余部分具有相同的格式。感觉问题已经得到了答案，但我找到的答案或东西都没有返回正确的答案。

Answer 1

为小部件使用了错误的类。把

'Fecha': forms.DateField(widget=NumberInput(attrs={'type':'date'})),

'Fecha': forms.DateInput(widget=NumberInput(attrs={'type':'date'})),
^^^^^^^^^

forms.DateField用于声明表单的字段。它没有验证所需的方法value_from_datadict()。forms.DateInput是用于日期输入的小部件。它有所需的方法。
