how to display fixed dropdown in django admin?

Question

Hi all,

I would like to display priority information in a drop down. Currently i am using a integer field to store the priority, but i would like to display high/medium/low instead of letting user type in a priority.

A way to approximate this is to use a Priority database which stores 3 elements, 1:high, 2:medium, 3:low, but it seems like an overkill.

Any easier way would be much appreciated!

Answer 1

You should be able to add choices to the model element

So:

class myModel(models.Model):
    mydata = models.CharField(max_length=4, choices= ((u'H', u'High',), (u'M', u'Medium'), (u'L', u'Low')))

Would store H,M,L in the DB, but present High, Medium, Low. Admin defaults fields with the choices attribute to a drop down selector

Answer 2

You can specify choices for a field http://www.djangoproject.com/documentation/models/choices/.

PRIORITY_CHOICES = ((1, 'High'),
                    (2, 'Medium'),
                    (3, 'Low'))

class MyModel(models.Model):
    priority = models.IntegerField(choices=PRIORITY_CHOICES)

Answer 3

You could write your model like this:

from django.db import models

class Priority(models.Model):
    PRIORITY_LOW = 3
    PRIORITY_MEDIUM = 2
    PRIORITY_HIGH = 1

    PRIORITY_CHOICES = (
        (PRIORITY_LOW, 'low'),
        (PRIORITY_MEDIUM, 'medium'),
        (PRIORITY_HIGH, 'high'),
    )

    priority = models.IntegerField(choices=PRIORITY_CHOICES)
