So what I'm trying to do is display a model on a page and then use a form to update said model on the page. I've managed to create a form and display it on the page, and I have managed to create to create a model--though I haven't gotten to display it on the page.
This is what I have so far for the form:
from django import forms
class IndexForm(forms.Form):
post = forms.CharField()
This is my models:
from django.db import models
class Post(models.Model):
post = models.CharField(max_length=141)
My views:
from django.shortcuts import render
from firstapp.forms import IndexForm
from django.views.generic import TemplateView
from firstapp.models import Post
class HomePage(TemplateView):
template_name = 'home/home.html'
def get(self, request):
form = IndexForm()
posts = Post.objects.all()
args = {'form': form, 'posts': posts}
return render(request, self.template_name, args)
This is my base.html:
{% load staticfiles %}
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Home</title>
<link rel='stylesheet' href='{% static "css/base.css" %}'/>
</head>
<body>
{% block body %}{% endblock %}
<script src= '{% static "js/base.js" %}'></script>
</body>
</html>
And finally my home.html:
{% extends 'base.html' %}
{% block body %}
<div class="container">
<p>Home</p>
<form method="post">
{% csrf_token %}
{{ form.as_p }}
<button type="submit">Submit</button>
</form>
</div>
{% endblock %}
So how would I go about changing this so the home page would display a form and a model with something like "Name: [Your Name]" and when you input your name in the form, the model would update itself to be "Name: ‘input’"?
I've been trying to figure this out for a week to no success, so I truly appreciate the help. Thank you!

Sounds like you want a ModelForm. Docs are here: https://docs.djangoproject.com/en/1.11/topics/forms/modelforms/
