Hi Everyone, 

I am having Field Error while trying to have date field in my admin.py. There is some problem with Date Filed and I am unable to figure out what wrong I am doing. here is my code:

MODEL.PY

from django.db import models


import datetime
from django.utils import timezone


class Movie(models.Model):
    movie_title = models.CharField(max_length=200)
    movie_director = models.CharField(max_length=200)
    movie_writer = models.CharField(max_length=200)
    movie_musician = models.CharField(max_length=200)
    movie_intro = models.TextField()
    posted = models.DateField(db_index=True, auto_now_add=True)


    def __str__(self):
        return self.cd_movie


    def is_latest(self):
        return self.posted >= timezone.now() - datetime.timedelta(days=1)


    is_latest.admin_order_field = 'posted'
    is_latest.boolean = True
    is_latest.short_description = 'Latest?'

################

ADMIN.PY 

from django.contrib import admin
from movie.models import Movie




############
##    movie_title = models.CharField(max_length=200)
##    movie_director = models.CharField(max_length=200)
##    movie_writer = models.CharField(max_lenth=200)
##    movie_musician = models.CharField(max_length=200)
##    movie_intro = models.TextField()
##    posted = models.DateField(db_index=True, auto_now_add=True)
#############


class MovieAdmin(admin.ModelAdmin):
    fieldsets = [
        ('Movie Info',               {'fields': ['movie_title','movie_director','movie_musician','movie_writer']}),
        ('Movie Intro',               {'fields': ['movie_intro']}),
        ('Date information', {'fields': ['posted']}),
    ]




    list_display = ('movie_title', 'posted', 'is_latest')
    list_filter = ['posted']
    search_fields = ['movie_title']


admin.site.register(Movie, MovieAdmin)
