How to add multiple emails in an EmailField on a Django Model?

Question

I'm trying to create a Client Model with an email field that can contains one or multiple email addresses.

I know that there's the EmailField type that accepts a single email address, but in my case, I need to extend this to accept multiple email addresses:

class Client(models.Model):
    company_name = models.CharField(max_length=100, unique=True)
    project = models.ForeignKey(Project, blank=True, null=True,
        on_delete=models.SET_NULL)
    email_list = models.EmailField(max_length=70)

How can I achieve this to extend email_list capacity for multiple email addresses?

Answer 1

The EmailField can't be used for list.

You can create another model and use a ForeignKey

class Client(models.Model):
    company_name = models.CharField(max_length=100, unique=True)
    project = models.ForeignKey(Project, blank=True, null=True, on_delete=models.SET_NULL)


class Email(models.Model):
    client = models.ForeignKey(Client on_delete=models.CASCADE)
    email_list = models.EmailField(max_length=70)

Or a CharField like that:

class Client(models.Model):
    company_name = models.CharField(max_length=100, unique=True)
    project = models.ForeignKey(Project, blank=True, null=True, on_delete=models.SET_NULL)
    email_list = models.CharField(max_length=1000)


Client.objects.create(company_name="test", project=project_instance, email_list=json.dumps(email_list))

But the second one, I think, is not good, and you will lost the EmailField validate.
