Hi men, now i have my model is thus:
from django.core.mail import send_mail, mail_admins
from django.db import models
from django.template.defaultfilters import slugify
from django.core.urlresolvers import reverse
from django.contrib.auth.models import User
from ckeditor.fields import RichTextField
from subtopic.models import Subtopic
from topic.models import Topic
from keywords.models import KeyWord
#Global Vars
# Create your models here.
class New(models.Model):
author = models.ForeignKey(User, verbose_name='Autor', related_name=
'news')
content = RichTextField(verbose_name='Contenido')
created_date = models.DateTimeField(auto_now_add=True, verbose_name='Fecha
y Hora')
is_published = models.BooleanField(verbose_name='Publicada', default=
False,) #Nueva, para verificar si se publica o no
keywords = models.ManyToManyField(KeyWord, blank=True,
verbose_name='Palabras
Clave', related_name='news')
place = models.CharField(max_length=255, verbose_name='Lugar')
source = models.URLField(verbose_name='Fuente', blank=True)
subtopic = models.ForeignKey(Subtopic, verbose_name='Subtema',
related_name='news') #Filtramos por Opinion para sacar todas las columnas
times_viewed = models.PositiveIntegerField(default=0, editable=False,
verbose_name='Veces Vista' )
title = models.CharField(verbose_name='Título', max_length=255, unique=
True)
slug = models.SlugField(verbose_name='Slug', max_length=100, unique=
True)
topic = models.ForeignKey(Topic, verbose_name='Tema', related_name=
'news', )
class Meta:
ordering = ['-created_date']
verbose_name_plural = 'Noticias'
verbose_name = 'Noticia'
permissions = (
("can_publish", "Puede publicar noticias"), #Can publish news
)
def first_image(self):
return self.images.first() # Siendo images el related_name en Image
def first_video(self):
return self.videos #Devuelve el video de la imagen
def get_absolute_url(self):
return reverse ('NewsDefaultView', args = [str(self.created_date.
strftime("%Y")), str(self.created_date.strftime("%m")), str(self.
created_date.strftime("%d")), str(self.slug)])
def get_all_keys(self):
keys_list = self.keywords.values_list('name', flat=True)
return str(keys_list).strip("'[]'").replace("'",'')
#def is_published(self): devuelve si la noticia ha sido pulicada para
que salga en la lista de noticias
def __str__(self):
return self.title
def save(self): #Definir metodo para guardar, validar y otros metodos
del Slug
super(New, self).save() #Solo con este me funciona correctamente
if not self.id:
self.slug = slugify(self.title)
super(New, self).save()
def get_queryset(self, request):
queryset = super(New, self).get_queryset(request)
if request.user.groups.filter(name="Author").exist(): # is the
user an author?
queryset = queryset.filter(author=self.user) # only allow
users to edit their own posts
return queryset
def get_readonly_fields(self, request, obj=None):
readonly_fields = super(New, self).get_readonly_field(request, obj)
if request.user.groups.filter(name="Author").exist(): # is the
user an author?
readonly_fields += ['is_published'] # don't allow authors to
change the publish status
return readonly_fields
from django.db.models.signals import post_save
def send_notification(sender, **kwargs):
return mail_admins('Nueva noticia espera por edición','Una nueva
noticia ha sido creada y espera ser editada y publicada muy pronto, anda,
te esperamos.', )
post_save.connect(send_notification, sender=New)
from permission import add_permission_logic
from permission.logics import AuthorPermissionLogic, StaffPermissionLogic
add_permission_logic(New, AuthorPermissionLogic(
field_name='author',
any_permission=False,
change_permission=True,
delete_permission=True,
))
add_permission_logic(New, StaffPermissionLogic(
any_permission=False,
change_permission=True,
delete_permission=True,
))
from django.core.cache import cache
from django.db.models.signals import post_save
from django.dispatch import receiver
from django.contrib.sessions.models import Session
@receiver(post_save)
def clear_cache(sender, **kwargs):
if sender != Session:
cache.clear()
But, don't works, the author user can change other news and can publish
:'(, what i'm doing bad?
I can created a group in python code? in models.py or other file or only
can created a group in django admin?
