Django 1.7模型，指定了未知字段（日期）

Question

I added a model to an application, and now I get this error:

Unknown field(s) (date) specified for appname

I have tried python manage.py migrate appname and it says there are no migrations to make. I've even tried deleting my database and using migrate and/or syncdb to recreate it with a clean slate. (there's currently no data in there). All to no avail.

My problem seems similar to: Django 1.7 remove field. Unknown field(s) (field) specified for Model

Answer 1

i figured it out. the problem was with a model form importing a date field with auto_now=True.

Answer 2

I had the same issue, following wasn't working throwing same error as above -

publication_date = models.DateTimeField(auto_now=True, null=True, blank=True)

Where as following worked fine -

publication_date = models.DateTimeField(null=True, blank=True)

Strange issue with using auto_now=True . Is this limited to version 1.7 only?

Answer 3

您应该尝试使用默认值=“ xxx”修改auto_now和auto_now_add
