Re: How create a custom permission for a model?

Wel wel wel, my code is it :

news.models.py

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
        )

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,
))

As you can see, i'm using django-permission.

What have i do ?

These can be done using built in permissions and groups

Something like this might work for the rest:

class NewsAdmin(models.Model):

    def get_queryset(self, request):
        queryset = super(NewsAdmin, 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(NewsAdmin, self).get_readonly_field(request, obj)
        if request.user.groups.filter(name="Author").exist():  # is the user an author?
            readonly_fields += ['published']  # don't allow authors to change the publish status
        return readonly_fields
