I'm using Python 2.7.3 and Django 1.4.5-1 from Debian repositories. I can
add multiple entries with identical values and the admin interface doesn't
complain. I tried with both 'slug' and 'title'.
It sounds just like the bug from 4 years ago:
https://code.djangoproject.com/ticket/10134
Note that while my field is DateTimeField (with time), the wording of the
description at
https://docs.djangoproject.com/en/dev/ref/models/fields/#unique-for-date
leads me to believe it should consider only the .date component of the
DateTimeField.
{{{
# models.py
from django.db import models
from django.utils.timezone import now as utcnow
now = utcnow() # replacing - date.now() causes problems with auto_now_add
class Entry(models.Model):
created_at = models.DateTimeField(default=now, editable=False)
title = models.CharField(max_length = 50)
content = models.TextField()
slug = models.SlugField(unique_for_date='created_at')
def __unicode__(self):
return self.title
class Meta:
ordering = ['-created_at']
# admin.py
from news.models import Entry
from django.contrib import admin
class EntryAdmin(admin.ModelAdmin):
prepopulated_fields = {'slug': ('title',)}
list_filter = ['created_at']
date_hierarchy = 'created_at'
admin.site.register(Entry, EntryAdmin)
}}}
