__init __()获得了意外的关键字参数'required'

问题描述

由于某种原因，Django不允许将参数required=False传递给我的表单字段.

For some reason, Django is not letting pass the parameter required=False to my form fields.

这是我的表格:

class InstrumentSearch(forms.ModelForm):
    groups = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple, required=False)
    time = forms.TimeInput(required=False)
    date = forms.DateField(required=False)
    notes = forms.TextInput(required=False)

错误就在线上

time = forms.TimeInput(required=False)

根据此处的Django文档，这应该绝对可以.

According to the Django Documentation here, this should absolutely work.

推荐答案

像 TimeInput 继承自窗口小部件(通过TextInput)，它接受一个字典中的属性作为attrs参数. TextInput的示例显示对必填项的使用:

Looks to me like TimeInput inherits from Widget (via TextInput), which accepts attributes in one dictionary as the attrs argument. The examples with TextInput show use of required:

>>> name = forms.TextInput(attrs={'required': False})

相比之下，TimeField和CharField之类的Field子类确实接受您使用的关键字参数.

By contrast, Field subclasses such as TimeField and CharField do accept keyword arguments like you use.
