How can we add more than 3 authors field for a single magzine? in Django models

Question

I created a magzine model in django. But their are more than three authors of a magzine. I have written below code for three authors. If I write the code of two or three author for a single magzine then it is looks somewhat good. But if I make for more than three authors then it will looks very bad. Now I am confused, Is the method that I have created is wrong? And if it is wrong then how should I write it?

    author_name1 = models.CharField(max_length=300, blank=True)
    designation1 = models.CharField(max_length=100, blank=True)
    author_pic1 = models.ImageField(upload_to="authorpic", blank=True)
    author_detail1 = models.TextField(max_length=1000, blank=true)
    author_name2 = models.CharField(max_length=300, blank=True)
    designation2 = models.CharField(max_length=100, blank=True)
    author_pic2 = models.ImageField(upload_to="authorpic", blank=True)
    author_detail2 = models.TextField(max_length=1000, blank=true)
    author_name3 = models.CharField(max_length=300, blank=True)
    designation3 = models.CharField(max_length=100, blank=True)
    author_pic3 = models.ImageField(upload_to="authorpic", blank=True)
    author_detail3 = models.TextField(max_length=1000, blank=true)

You can make an extra model Author with a ForeignKey ^[Django-doc] to Magazine. If the same Author can write multiple Magazines, you might want to use a ManyToManyField ^[Django-doc] instead:

class Author(models.Model):
    name = models.CharField(max_length=300, unique=True)
    designation = models.CharField(max_length=300, blank=True)
    picture = models.ImageField(upload_to_authorpic, blank=True)
    detail = model.TextField(max_length=1000, blank=True)

class Magazine(models.Model):
    # …
    authors = models.ManyToManyField(
        Author,
        related_name='magazines',
        on_delete=models.CASCADE
    )

You probably want to make name a unique=True ^[Django-doc] field to avoid creating two Author objects with the same name.
