Question

Here is my code:

from League.models import Leagues
from League.models import Team
from django.contrib import admin

class TeamsInLeague(admin.StackedInline):
    model = Team
    extra = 1

class LeagueAdmin(admin.ModelAdmin):
    fields = ['LeagueName']
    inlines = TeamsInLeague

admin.site.register(Leagues,LeagueAdmin)

it gives me the error:

'LeagueAdmin.inlines' must be a list or tuple.

It works fine when I remove inlines = TeamsInLeague

I am following the tutorial, not to the word, but trying to solve my own problem.

Answer 1

The error is pretty clear — inlines should be a list or tuple, not a class. Use

inlines = [TeamsInLeague]

or

inlines = (TeamsInLeague,)
