When delete a record in admin raise error :

Django Version: 1.4

in Model.py:

class News(models.Model):
title = models.CharField(max_length=150)
newstype = models.ForeignKey(NewsType)
newssource = models.CharField(null=True,blank=True,max_length=250)
newsurl = models.CharField(null=True,blank=True,max_length=250)
newsdate = models.DateTimeField(auto_now=True, editable = False)
newscontext=HTMLField(verbose_name='news')
rateperson = models.ManyToManyField(Person,null=True, blank=True,related_name="news_person")
ratetvplay = models.ManyToManyField(Tvplay,null=True,blank=True,related_name="news_tvplay")
edtor = models.ForeignKey(User)
published = models.BooleanField(default=False)

def __unicode__(self):
return self.title

In admin.py:

class NewsAdmin(admin.ModelAdmin):
list_display = ('title','newstype','newsdate',)
search_fields=('title',)
list_filter =('newstype',)
delete_selected_confirmation_template = True
raw_id_fields = ('rateperson','ratetvplay',)
admin.site.register(News,NewsAdmin)

When I delete multi record by delete action in django-admin form
Raise error: 'bool' object has no attribute 'render'
