Cannot see blog posts in index.html

Question

I am trying to make a simple blog website. I have created my files and models. The page shows up fine, and the admin works. I have created a few posts in the admin for testing. However, the blogs do not reflect on index.html from the admin page. I included the app in settings.py. All the other pages work, so I don't think the issue is with the file structure.

models.py
from django.db import models
from django.contrib.auth.models import User
from django.urls import reverse
from django.utils import timezone

class Todo(models.Model):
    title = models.CharField(max_length=100)
    memo = models.TextField(blank=True)
    created = models.DateTimeField(auto_now_add=True)
    datecompleted = models.DateTimeField(null=True, blank=True)
    important = models.BooleanField(default=False)
    user = models.ForeignKey(User, on_delete=models.CASCADE)

    def __str__(self):
        return self.title


class Post(models.Model):
    title = models.CharField(max_length=200, default='', unique=True)
    first_name = models.CharField(max_length=50, default='', editable=False)
    last_name = models.CharField(max_length=50, default='', editable=False)
    body = models.TextField(default='')

def __str__(self):
    return self.title

urls.py (Project)

Your index view function isn't sending anything for object_list to the template.

def index(request):
    # will get every post
    posts = Post.objects.all()
    return render(request, 'todo/index.html', {'object_list': posts})
