Re: How to display user's photo that i follow in post's list in Django

If I'm following correctly and you want to access author profile photos from querysets of Post objects: if you add related_name='profile' to the user field in the Profile model then you can add a method to the Post model:

def author_profile_photo(self):
    return self.author.profile.photo

and then access the photos in the template using {{ post.author_profile_photo }}
You will need to catch cases where there is no photo either in the class method or the template to avoid an error, eg.
{% if post.author_profile_photo %} {{ post.author_profile_photo }} {% else %} {{ <placeholder image>}} {% endif %}

That get_photo func, I'm not using it. It tried to do something and I forgot to delete it.

About screenshotting the code, I thought that it was more clarifying.

class ProfileManager(models.Manager):
    use_for_related_fields = True

    def all(self):
        qs = self.get_queryset().all()
        try:
            if self.instance:
                qs = qs.exclude(user=self.instance)
        except:
            pass
        return qs

    def toggle_follow(self, user, to_toggle_user):
        user_profile = user.profile
        if to_toggle_user in user_profile.following.all():
            user_profile.following.remove(to_toggle_user)
            adedd = False
        else:
            user_profile.following.add(to_toggle_user)
            adedd = True
        return adedd

    def is_following(self, user, followed_by_user):
        user_profile = user.profile
        if followed_by_user in user_profile.following.all():
            return True
        return False


class Profile(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
    following = models.ManyToManyField(settings.AUTH_USER_MODEL, blank=True, related_name='followed_by')
    date_of_birth = models.DateField(blank=True, null=True)

    education = models.CharField(max_length=150, blank=True, null=True)

    objects = ProfileManager()

    def __str__(self):
        return 'Profile for user {}'.format(self.user.username)

    def get_following(self):
        users = self.following.all()
        return users.exclude(username=self.user.username)

    @receiver(post_save, sender=User)
    def create_or_update_user_profile(sender, instance, created, *args, **kwargs):
        if created:
            Profile.objects.create(user=instance)

            instance.profile.save() 

class Post(models.Model):
    author = models.ForeignKey(settings.AUTH_USER_MODEL)
    profile = models.ForeignKey(Profile)
    title = models.CharField(max_length=200)
    content = models.TextField()
    image = models.FileField(upload_to='posts/', blank=True)
    created = models.DateTimeField(auto_now_add=True, db_index=True)
    modified = models.DateTimeField(auto_now=True)
    slug = models.SlugField(unique=True)
    likes = models.PositiveIntegerField(default=0)

    @property
    def total_likes(self):
        return self.likes.count()

    def __str__(self):
        return self.title

    class Meta:
        ordering = ["-created"]

    def get_absolute_url(self):
        return reverse("detail", kwargs={"slug": self.slug})

    def _get_unique_slug(self):
        slug = slugify(self.title)
        unique_slug = slug
        num = 1
        while Post.objects.filter(slug=unique_slug).exists():
            unique_slug = '{}-{}'.format(slug, num)
            num += 1
        return unique_slug

    def save(self, *args, **kwargs):
        if not self.slug:
            self.slug = self._get_unique_slug()
        super(Post, self).save()

This is copy/pasting it :)

I still need to make that queryset to show a list of posts the users that I follow(and myself) with Profile combined or showing the post.content and profile.photo.

Hi,

not sure why you're screenshotting code instead of copying it...makes it
harder to point you at the mistake.

in Profile.get_photo() you set users to self.photo. I don't think you
wanted to do that.
