Populate Month Based On Date Field In Django

I would like to have a field auto-generate the month based on the date entered before it. models.py class Projects(models.Model): Name = models.CharField(max_length=100, null=

Solution 1:

You can simply override your save to add the auto-field instead of calling save in a new method:

classProjects(models.Model):
    Name = models.CharField(max_length=100, null=True, blank=False) 
    Date = models.DateField(null=True, blank=False)
    Month = models.CharField(max_length=100, null=True, blank=False)  

    defsave(self, *args, **kwargs):
        if self.Date: 
            self.Month = self.Date.strftime("%B")
        super(Model, self).save(*args, **kwargs)

But the above will make Month available only after the instance has been saved.

You can instead create a property, so that Month is available from an instance of the model and also prevent adding duplicate info in your DB:

classProjects(models.Model):
    Name = models.CharField(max_length=100, null=True, blank=False) 
    Date = models.DateField(null=True, blank=False)

    @propertydefMonth(self):
        if self.Date:
            return self.Date.strftime("%B")
        return"No date entry"

You can use the property like so:

import datetime.date as dt

# import your Projects model
p = Projects(Name='ceuskervin', Date= dt.today())

print(p.Month)
