We're going to learn how to work with a database outside of using the django admin panel.

create room_form.html  inside  main/templates/main

{% extends 'main.html' %}

{% block content %}

<div>

    <form method="POST" action="" >

        {% csrf_token %}

            {{form.as_p}}

            <input type="Submit" value="Submit" />

    </form>

</div>

{% endblock content %}

POST; for creating and updating , if I don't specify the action, it's going to send it to the current url that we're at. csrf_token this token will be sent on every form submit so when we're sending post requests in django we need to pass in this token; we're just sending that token along with every request and it's making sure that the user didn't try to do anything malicious with that.

and go to views.py

def createRoom(request):

    form = RoomForm()

    if request.method == 'POST':

        form = RoomForm(request.POST)

        if form.is_valid():

            form.save()

            return redirect('home')

    context = {'form': form}

    return render(request, 'main/room_form.html', context)

and url.py

urlpatterns = [

path('', views.home, name="home"),

path('room/<str:pk>/', views.room, name="room"),

path('create-room/', views.createRoom, name="create-room"),

Le'ts go into our home.tml page and this is where a user can create a room from. 

    <a href="{% url 'create-room' %}">Create Room</a>

Now you see "submit" on the page. 

we're going to make new file.. 

main/forms.py

from django.forms import ModelForm

from .models import Room

class RoomForm(ModelForm):

    class Meta:

        model = Room

        fields = '__all__'

fields = '__all__' is going to create the form based on the metadata of the room
