Suggested model structure to achieve users selection of services/package

[Gavin Boyle]

I am building an application that offers different services, a user can select and purchase specific needed packages. I want to know the best way to create the model so that our users can select and once paid it sets the service to active. I have one model that holds information about each individual services which includes (Package Title / Description / Price ). I need another model to handle what services are associated to each user but I am unsure how to go about this.

I have created two models as shown below but unsure how I can accomplish the above as I believe there is a better was to accomplish this.

# Model to store club information on what clubs have access to what packages
class ClubPackages(models.Model):

    club_id = models.ForeignKey(ClubInfo, on_delete=models.CASCADE)
    PACKAGE_STATUS = (
        ('0', 'Active'),
        ('1', 'Not Active')
    )
    player_register_package = models.CharField(default='1', max_length=1, choices=PACKAGE_STATUS)
    player_register_price = models.DecimalField(default=100.00, max_digits=8, decimal_places=2)
    player_register_expiry = models.DateField(default=timezone.now)
    roster_package = models.CharField(default='1', max_length=1, choices=PACKAGE_STATUS)
    roster_price = models.DecimalField(default=50.00, max_digits=8, decimal_places=2)
    roster_expiry = models.DateField(default=timezone.now)
    rent_a_pitch_package = models.CharField(default='1', max_length=1, choices=PACKAGE_STATUS)
    rent_a_pitch_price = models.DecimalField(default=100.00, max_digits=8, decimal_places=2)
    rent_a_pitch_expiry = models.DateField(default=timezone.now)
    shop_package = models.CharField(default='1', max_length=1, choices=PACKAGE_STATUS)
    shop_price = models.DecimalField(default=50.00, max_digits=8, decimal_places=2)
    shop_expiry = models.DateField(default=timezone.now)

# Model to store our available packages
class OurPackages(models.Model):

    title = models.CharField(max_length=50)
    description = models.TextField(max_length=200)
    price = models.DecimalField(max_digits=8, decimal_places=2)

    def __str__(self):
            return self.title
