Django 创建模型实例时未设置BooleanField默认值

当创建具有

布尔字段
my_boolean_字段
且
默认值设置为
True
的模型实例时，我得到一个错误：

my_boolean_field is required

不应该设置为默认值吗

models.py

管理员

更改模型表单中的字段定义，以指定
require=False

class MyModelCreationForm(UserCreationForm):   

    my_boolean_field = forms.BooleanField(initial=False, required=False)

    class Meta:
        model = User

关于

注
由于默认情况下所有字段子类都具有required=True，因此此处的验证条件很重要。如果您希望在表单中包含一个布尔值，该布尔值可以是真的，也可以是假的（例如，选中或未选中的复选框），则必须记住在创建布尔字段时输入required=False

好的，我想如果用户没有设置它，它会被设置为默认值。
class MyModelCreationForm(UserCreationForm):   

    my_boolean_field = forms.BooleanField(initial=False)

    class Meta:
        model = User

class MyModelChangeForm(UserChangeForm):

    my_boolean_field = forms.BooleanField(initial=False)

    class Meta:
        model = User


class MyModelAdmin(UserAdmin):

    form = MyModelChangeForm
    add_form = MyModelCreationForm

    list_filter = ()
    list_display = ('username', 'my_boolean_field')

    fieldsets = (
        (None, {'fields': ('username', 'my_boolean_field', 'password' )}),
    )


    add_fieldsets = (
        (None, {
            'classes': ('wide',),
            'fields': ('username', 'my_boolean_field', 'password1', 'password2')}
        ),
    )

    def get_form(self, request, obj=None, **kwargs):
        form = super(MyModelAdmin, self).get_form(request, obj, **kwargs)
        if obj==None:
            form.base_fields['username'].widget.attrs['autocomplete'] = 'off'
            form.base_fields['password1'].widget.attrs['autocomplete'] = 'off'
            form.base_fields['password2'].widget.attrs['autocomplete'] = 'off'
        return form

samsic_site.register(MyModel, MyModelAdmin)

class MyModelCreationForm(UserCreationForm):   

    my_boolean_field = forms.BooleanField(initial=False, required=False)

    class Meta:
        model = User
