Thanks for all the replies and I think I'm getting it now but it gets more
complex too.
So NRA Licenses is essentialy going to become a type of several
certifications. For instance.
NRA Instructor
- Home Firearm Safety Instructor
- Refuse to be a Victim Workshop
- and many more could be selected.....
CCL (or CCW in some states)
- State in Which your Certified (possibility of multiple states)
Many more different types of licenses and certifications are going to be
added eventually so as you can see these relationships are going to get
complex. So If I'm grasping this correctly let me try some code to see if
I'm on the right track....
class NRA_Certs(models.Model):
CRSO = models.BooleanField(blank=True, null=True, "Chief Range Safety
Officer")
HFS = models.BooleanField(blank=True, null=True, "Home Firearm Safety")
MCR = models.BooleanField(blank=True, null=True, "Metallic Cartridge
Reloading")
PPH = models.BooleanField(blank=True, null=True, "Personal Protection
in the Home")
PPO = models.BooleanField(blank=True, null=True, "Personal Protection
Outside the Home")
PS = models.BooleanField(blank=True, null=True, "Pistol Shooting")
RS = models.BooleanField(blank=True, null=True, "Rifle Shooting")
SSR = models.BooleanField(blank=True, null=True, "Shotgun Shell
Reloading")
SS = models.BooleanField(blank=True, null=True, "Shotgun Shooting")
RTBVDW = models.BooleanField(blank=True, null=True, "Refuse to be a
Victim Workshop")
RTBVO = models.BooleanField(blank=True, null=True, "Refuse to be a
Victim Online")
NMLRA_MP = models.BooleanField(blank=True, null=True, "NMLRA
Muzzleloading Pistol Shooting")
NMLRA_MR = models.BooleanField(blank=True, null=True, "NMLRA
Muzzleloading Rifle Shooting")
NMLRA_MS = models.BooleanField(blank=True, null=True, "NMLRA
Muzzleloading Shotgun Shooting")
class NRA(models.Model):
cert_type = models.ForeignKey(NRA_Certs)
name = models.CharField() # Is this necessary? Can the name be set to
text in the boolean fields from NRA_Certs?
expiration = models.DateField(blank=True, null=True)
Does that look right or am I missing it completely. I'm not sure sure on
the NRA_Certs all being boolean, my thinking is that whether they have that
certification should be as simple as true/false.
Thanks once again for all the help.
