Django POST - unable to retrieve form data, POST check fails

I'm very new to Django. I am trying to desing my login module and trying to print the values i submit.

  1. login.html (please excuse indentation mistakes)

    {% load staticfiles %}

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Login Form</title>
    <link rel="stylesheet" href="{% static 'css/lstyle.css' %}"> 
</head>

<body>
{% block content %}
{% if form.errors %}
    <script> alert("Your username and password didn't match. Please try 
again."); </script>
{% endif %}

{% if next %}
{% if user.is_authenticated %}
    <script> alert("Your account doesn't have access to this page. To 
    proceed,please login with an account that has access."); </script>
{% else %}
    <script> alert('Please login'); </script>
{% endif %}
{% endif %}
<div class="login">
    <div class="login-screen">
        <div class="app-title">
            <h1>Login</h1>
        </div>
        <div class="login-form">
                <form method="POST" action="{% url 'login' %}">
{% csrf_token %}
                    <p class="bs-component">
                        <table>
                            <tr>
                                <td>{{ form.username }}</td>
                            </tr>
                            <tr>
                                <td>{{ form.password }}</td>
                           </tr>
                            <tr>
                                <td>{{ form.schoolID }}</td>
                            </tr>
                        </table>
                    </p>
                    <p class="bs-component">
                        <center>
                            <input class="btn btn-success btn-sm" 
                            type="submit" value="login" />
                        </center>
                    </p>
                    <input type="hidden" name="next" value="{{ next }}" 
                    />
                </form>
        </div>
    </div>
</div>
</body>
{% endblock %}
</html>

  2. Forms.py

    from django.contrib.auth.forms import AuthenticationForm
from django import forms


# If you don't do this you cannot use Bootstrap CSS
class LoginForm(AuthenticationForm):
      username = forms.CharField(max_length=30,
                       widget=forms.TextInput(attrs={'class': 
                       'form-control', 'name': 'username', 'placeholder': 'Username'}))
      password = forms.CharField(max_length=30,
                       widget=forms.PasswordInput(attrs={'class': 
                       'form-control', "name": 'password', 'placeholder': 'Password'}))
      schoolID = forms.CharField(max_length=100,
                       widget=forms.TextInput(attrs={'class': 
                       'form-control', 'name': 'schoolid', 'placeholder': 'School ID'}))

  3. Views.py

    from django.shortcuts import render, redirect
from django.contrib.auth.decorators import login_required
from home.forms import LoginForm
from home.models import UserProfile
from django.views.generic import TemplateView
from django.contrib.auth.models import User


@login_required(login_url="login/")
def home(request):
    if request.method == 'POST':
        myform = LoginForm(request.POST)
        print(myform.data['schoolID'])
        return render(request, "home.html")

Things working:

  1. html file renders perfectly.

  2. User authentication works

  3. if the "return render(request, "home.html")" is placed outside the if block, the code runs perfectly, and i am redirected to home.html - by entering matching username and password.

Things not working:

  1. Unable to print schoolID. i.e, the "if request.method == 'POST':" is not being executed.

  2. The error: The view home.views.home didn't return an HttpResponse object. It returned None instead.

what am i doing wrong here. I just want to print the form data and do operations with it before i execute the return statement. Please help.

use myform = LoginForm(data=request.POST)

OR myform = LoginForm(None , request.POST)

because request is not the first parameter.
