datefield

I have a question in Django on how you can compare dates to solve some solutions. For example I have a datefield in my models.py Like below. class Invoice(models.Model): payment_date = models.DateTimeField() What I want to be able to do is ask if the is a way to compare a datetime.now with a DateTimeField. For example, if I had a list of payment dates and I wanted to compare with datetime now. Thhe payment_date's that are late with their payments are shown in owing. Otherwise, it the value is zero. Here is my views to show whats going on. I have tried so far but I get a 0 value for payment

I am creating a django application and I have the next problem: this error is shown when I want to set a date: ValidationError [u"'12/06/2012' value has an invalid date format. It must be in YYYY-MM-DD format."] For this model: class ModelA(models.Model): date1 = models.DateField(null=True) date2 = models.DateField(null=True) How can I set the DateField format to be %m/%d/%Y .

I was pleasantly surprised to discover that the following code, when viewed in Chrome, renders a datepicker: <input type="date" name="wdate" id="wdate" value="" placeholder="date of purchase" /> However, the placeholder text is ignored and "Date/Month/Year" is shown instead. How can I change the placeholder text and use my own? I have already tried: <script> $("#wdate").attr("placeholder", "Day/Month/Year of purchase"); </script> but to no avail. The date type doesn't support placeholder attribute. Also, the WebKit implementation says it's fixed. Older question, but here is the solution I

I've got a model where I need to store birth year. I'm using django admin. The person using this will be filling out loads of people every day, and DateField() shows too much (not interested in the day/month). This is a mockup model showing how it is now: class Person(models.Model): name = models.CharField(max_length=256) born = models.IntegerField(default=lambda: date.today().year - 17) As you can see, most of the people is 17 years old, so I'm getting their birth year as default.
