python - Create a like button for blog posts in my Django?

Question

I've been trying to create a like button for my blog posts in my Django blog but I can't figure out how to create one because it contain Integer .

When the user clicks on the like button . The like button will increase and it will display near the post.

This is my like module:

class Post(models.Model):
    title = models.CharField(max_length=225)
    post_image = models.ImageField(null=True, blank=True,  upload_to="images/")
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    body = models.TextField()
    post_date = models.DateField(auto_now_add=True)
    
    
    def __str__(self):
        return self.title + ' | '  + str(self.author)

    def get_absolute_url(self):
        return reverse('post-detail', args=(str(self.id)),)

Thanks in advance

Answer 1

You should put two variables named likes and dislikes, Both with ManyToManyField.

class Post(models.Model):
    title = models.CharField(max_length=225)
    post_image = models.ImageField(null=True, blank=True,  upload_to="images/")
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    body = models.TextField()
    post_date = models.DateField(auto_now_add=True)
    likes = models.ManyToManyField(User, related_name='post_like', blank=True)
    dislikes = models.ManyToManyField(User, related_name='post_dislike', blank=True)


    def __str__(self):
        return self.title + ' | '  + str(self.author)

    def get_absolute_url(self):
        return reverse('post-detail', args=(str(self.id)),)

Now you can make two views. One for Like and the other for Dislike
