Require multiple entries for "Item", Django Admin - mysql

Question

I want to enter multiple entries for "item" under one "session_title" - and I think I understand I need a ManyToOne relationship (set with ForeignKey) but mysite/admin isn't showing multiple entries available? I am using DjangoAdmin to administer my app.
Edit/Add: I know there's a step I'm missing. I'm hoping for someone to send me there.
class Item(models.Model):
item_name = models.TextField(unique=True)
class Meta:
managed = True
db_table = 'item'
def __str__(self):
return self.item_name
class SessionLog(models.Model):
date = models.DateField()
session_title = models.TextField(blank=True, null=True)
campaign = models.OneToOneField(Campaign, models.DO_NOTHING, default="1")
chapter = models.OneToOneField(Chapter, models.DO_NOTHING, default="1")
scene = models.OneToOneField(Scene, models.DO_NOTHING, default="1")
character = models.OneToOneField(Character, models.DO_NOTHING, default="1")
location = models.OneToOneField(Location, models.DO_NOTHING, blank=True, null=True)
npc = models.OneToOneField(Npc, models.DO_NOTHING, blank=True, null=True)
monster = models.OneToOneField(Monster, models.DO_NOTHING, blank=True, null=True)
item = models.ForeignKey(Item, models.DO_NOTHING, blank=True, null=True)
loot_pp = models.IntegerField(blank=True, null=True)
loot_gp = models.IntegerField(blank=True, null=True)
loot_ep = models.IntegerField(blank=True, null=True)
loot_sp = models.IntegerField(blank=True, null=True)
loot_cp = models.IntegerField(blank=True, null=True)
session_xp = models.IntegerField(blank=True, null=True)
session_strongstart = models.TextField(blank=True, null=True)
session_secrets = models.TextField(blank=True, null=True)
session_clues = models.TextField(blank=True, null=True)
session_notes = models.TextField(blank=True, null=True)
class Meta:
managed = True
db_table = 'session_log'
def __str__(self):
return self.session_title
Could someone point me in the right direction? Thank you, in advance.

Yep, you're on the right track.
Change
item = models.ForeignKey(Item, models.DO_NOTHING, blank=True, null=True)
to
items = models.ManyToManyField(Item, on_delete=models.DO_NOTHING)
and in your admin, declare an Inline class:
class ItemInline(admin.TabularInline):
pass
class SessionLogAdmin(admin.ModelAdmin):
inlines = [ItemInline]
