Coming from Django world, what is the equivalent to __str__() function? It is used to represent the object in human readable format. For example, If I have Blog and Tag content. I would like to show each blog instance as "[id] - [blog title]", while creating a new Tag in the blog dropdown. How will I do this in strapi?

Django code:

class Blog(models.Model):
    name = models.CharField(max_length=255)
    tagline = models.TextField()

    def __str__(self):
        return "%s-%s" % (self.id, self.name)
