Feed with different type of feeds

[Allan-Nava]

I'm trying to implement 3 types of feed:

1. Status (message feed)
2. Video feed
3. Image feed

I'm using the feed class, feed type and for each type a specific class but I don't know how to connect the feed class with each type class(video class, image class)

Any suggestion?

Thanks for support

@sebastian-code I realize this feature, but i don't know how can I get the extra fields from the image feed or video feed inside the view.

This is my code:

@python_2_unicode_compatible
class Feed(models.Model):
    #STATUS OF FEEDS
    DRAFT       = 'D'
    PUBLISHED   = 'P'
    INVISIBLE   = 'I'
    VISIBLE     = 'V'

    # #TYPE OF FEEDS
    TYPE_STATUS = 'STATUS'
    # TYPE_IMG = 'IMAGE'
    # TYPE_VOD = 'VIDEO'
    # TYPE_MATCH = 'MATCH'

    STATUS = (
        (DRAFT, 'Draft'),
        (PUBLISHED, 'Published'),
    )


    user            = models.ForeignKey(User)
    date            = models.DateTimeField(auto_now_add=True)
    post            = models.TextField()
    parent          = models.ForeignKey('Feed', null=True, blank=True)
    likes           = models.IntegerField(default=0)
    comments        = models.IntegerField(default=0)
    #post_type   = models.TextField(null=True, blank=True)
    #media_url   = models.TextField(null=True, blank=True)

    media_url       = None
    #Custom fields
    post_type       = models.ForeignKey('FeedType')
    status          = models.CharField(max_length=1, choices=STATUS, default=DRAFT)
    tags            = TaggableManager()
    specific_post   = models.IntegerField(default=0)
    
    class Meta:
        verbose_name = _('Feed')
        verbose_name_plural = _('Feeds')
        ordering = ('-date',)

    class Meta:

        verbose_name_plural = _('FeedTypes')
        ordering = ('pk',)

Nothing I solved!

I wasn't able to understand completely your requirement, but I'm glad you solved it. The functionality, I'm not certain yet about it, but I think you choose a really complex path to implement it, you could also transform the original Feed model to an abstract model and inherit from it the other ones.

Is confusing, sorry :( i know 2017-12-06 17:42 GMT+01:00 Sebastian Reyes Espinosa < notifications@github.com>:

@sebastian-code Because the other type of feeds are sort of son..

This is my example in admin panel :)

[sebastian-code]

It looks really nice, thanks for sharing; as I stated before, I think I haven't been able to understand fully your whole requirement and the goals you have set for your project. It would be nice to see it when finished, so let me know when you have it, perhaps there something to learn from it and to implement here.

@Allan-Nava I am planning create different type of feeds like you. Could you share me your contact facebook or Skype?

[Allan-Nava]

@feedgit What do you need?
