在Django中创建数据库模型时，如何创建分别只接受一个月和一年的字段？

Question

If I use something like

   year_published = models.DateField()

then I have to enter in a day and month, in addition to a year. But in this field I only want to enter a year. Likewise, I only want to enter a month in

   month_published = models.DateField()

Any idea how to do this?

Answer 1

If you only store the year, how will you sort on Month and Date? Instead, store the full datetime object or split out the full date into three fields. As already mentioned, these would normally be Char fields, but can be Int and can be converted back to date to sort and compare/diff. See:

Or simply store the full date natively and then get the chunks you need from it as you need it. You might check out the Pendulum Package which opens up a lot more options on date operations.
