django: getting foreign key information - django

Question

I created a model with couple of classes and with foreign key and I was able to save it on the database.
I have the following models:
class Player_Bios(models.Model):
my_id = models.SlugField(unique=True)
player_id = models.IntegerField(max_length=50, unique=True)
name = models.CharField(max_length=50)
last = models.CharField(max_length=50)
middle = models.CharField(max_length=50, blank=True)
class BatStat (models.Model):
player_id = models.ForeignKey('Player_Bios')
team_id = models.ForeignKey('Team')
bat_stat_id = models.CharField(max_length=50, unique=True)
sport_code = models.CharField(max_length=50, blank=True)
ab = models.IntegerField(max_length=50, null=True)
class Team (models.Model):
team_id = models.IntegerField(max_length=50, unique=True)
team_short = models.CharField(max_length=50, blank=True)
team_full = models.CharField(max_length=50, blank=True)
When I save it to the database I can see that the team_id on the Team table is the same as the team_id on the BatStat table, but the player_id on the BatStat is different that the player_id on the Player_Bios table. This is how I save the data to the database:
p_id = Player_Bios.objects.get(player_id=st['player_id'])
t_id = Team.objects.get(team_id=st['team_id']) #I get the team_id from the Team Class
bat_id = str(st['season'])+ str(st['team_seq'])
bat_id = str(p_id.player_id) + bat_id
c = BatStat(player_id = p_id,team_id=t_id, bat_stat_id=bat_id, sport_code =st["sport_code"],ab=st['ab'])
c.save()
st['player_id'] is a dictionary. I did a print and it show the right player_id number

Answer 1

In BatStat you are storing the key to Player_Bios, which is not player_id
class Player_Bios(models.Model):
...
player_id = models.IntegerField(max_length=50, unique=True)
class BatStat (models.Model):
...
player_id = models.ForeignKey('Player_Bios')
I'm not sure why your team_id is the same, however, it seems like you already have the ids. You could avoid looking up the Player_Bios and Team by setting the id directly.
Django: Set foreign key using integer?
class Player_Bios(models.Model):
...
player_id = models.IntegerField(primary_key=True, max_length=50)
class Team (models.Model):
...
team_id = models.IntegerField(primary_key=True, max_length=50)
class BatStat (models.Model):
...
player = models.ForeignKey('Player_Bios') # notice i renamed this to not have '_id'
team = models.ForeignKey('Team') # notice i renamed this to not have '_id'
c = BatStat(bat_stat_id=bat_id,
sport_code =st["sport_code"],
ab=st['ab'])
c.player_id = st['player_id'], # notice that this has '_id'
c.team_id = st['team_id'], # notice this has '_id'
c.save()
