:DESCRIPTION: Get started with Django LiveView the easy way.
|
||||
:END:
|
||||
|
||||
All the steps are applied in a [[https://github.com/Django-LiveView/minimal-template][minimalist template]].
|
||||
|
||||
** 1. Install Django
|
||||
|
||||
Install Django, create a project and an app.
|
||||
|
||||
** 2. Install LiveView
|
||||
|
||||
Install django-liveview with ~pip~.
|
||||
|
||||
#+BEGIN_SRC sh
|
||||
pip install django-liveview
|
||||
#+END_SRC
|
||||
|
||||
** 3. Modify the configuration
|
||||
|
||||
Add ~liveview~ to your installed ~INSTALLED_APPS~.
|
||||
|
||||
#+BEGIN_SRC python
|
||||
INSTALLED_APPS = [
|
||||
"daphne",
|
||||
"channels",
|
||||
"liveview",
|
||||
]
|
||||
#+END_SRC
|
||||
|
||||
Then indicate in which previously created App you want to implement LiveView.
|
||||
|
||||
#+BEGIN_SRC python
|
||||
LIVEVIEW_APPS = ["website"]
|
||||
#+END_SRC
|
||||
|
||||
** 4. Migration
|
||||
|
||||
Execute the migrations so that the LiveView tables are generated.
|
||||
|
||||
#+BEGIN_SRC python
|
||||
python manage.py migrate
|
||||
#+END_SRC
|
||||
|
||||
** 5. ASGI
|
||||
|
||||
Modify the ASGI file, ~asgi.py~ to add the LiveView routing. In this example it is assumed that settings.py is inside core, in your case it may be different.
|
||||
|
||||
#+BEGIN_SRC python
|
||||
import os
|
||||
import django
|
||||
|
||||
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "core.settings")
|
||||
django.setup()
|
||||
|
||||
from channels.auth import AuthMiddlewareStack
|
||||
from django.core.asgi import get_asgi_application
|
||||
from channels.security.websocket import AllowedHostsOriginValidator
|
||||
from channels.routing import ProtocolTypeRouter, URLRouter
|
||||
from django.urls import re_path
|
||||
from liveview.consumers import LiveViewConsumer
|
||||
|
||||
|
||||
application = ProtocolTypeRouter(
|
||||
{
|
||||
# Django's ASGI application to handle traditional HTTP requests
|
||||
"http": get_asgi_application(),
|
||||
# WebSocket handler
|
||||
"websocket": AuthMiddlewareStack(
|
||||
AllowedHostsOriginValidator(
|
||||
URLRouter([re_path(r"^ws/liveview/$", LiveViewConsumer.as_asgi())])
|
||||
)
|
||||
),
|
||||
}
|
||||
)
|
||||
#+END_SRC
|
||||
|
||||
** 6. Create your first Action
|
||||
|
||||
Place where the functions and logic of the business logic are stored. We will start by creating an action to generate a random number and print it.
|
||||
|
||||
Create inside your App a folder called ~actions~, here will go all the actions for each page. Now we will create inside the folder a file named ~home.py~.
|
||||
|
||||
#+BEGIN_SRC python
|
||||
# my-app/actions/home.py
|
||||
from liveview.context_processors import get_global_context
|
||||
from core import settings
|
||||
from liveview.utils import (
|
||||
get_html,
|
||||
update_active_nav,
|
||||
enable_lang,
|
||||
loading,
|
||||
)
|
||||
from channels.db import database_sync_to_async
|
||||
from django.templatetags.static import static
|
||||
from django.urls import reverse
|
||||
from django.utils.translation import gettext as _
|
||||
from random import randint
|
||||
|
||||
template = "pages/home.html"
|
||||
|
||||
# Database
|
||||
|
||||
# Functions
|
||||
|
||||
async def get_context(consumer=None):
|
||||
context = get_global_context(consumer=consumer)
|
||||
# Update context
|
||||
context.update(
|
||||
{
|
||||
"url": settings.DOMAIN_URL + reverse("home"),
|
||||
"title": _("Home") + " | Home",
|
||||
"meta": {
|
||||
"description": _("Home page of the website"),
|
||||
"image": f"{settings.DOMAIN_URL}{static('img/seo/og-image.jpg')}",
|
||||
},
|
||||
"active_nav": "home",
|
||||
"page": template,
|
||||
}
|
||||
)
|
||||
return context
|
||||
|
||||
|
||||
@enable_lang
|
||||
@loading
|
||||
async def send_page(consumer, client_data, lang=None):
|
||||
# Nav
|
||||
await update_active_nav(consumer, "home")
|
||||
# Main
|
||||
my_context = await get_context(consumer=consumer)
|
||||
html = await get_html(template, my_context)
|
||||
data = {
|
||||
"action": client_data["action"],
|
||||
"selector": "#main",
|
||||
"html": html,
|
||||
}
|
||||
data.update(my_context)
|
||||
await consumer.send_html(data)
|
||||
|
||||
async def random_number(consumer, client_data, lang=None):
|
||||
my_context = await get_context(consumer=consumer)
|
||||
data = {
|
||||
"action": client_data["action"],
|
||||
"selector": "#output-random-number",
|
||||
"html": randint(0, 10),
|
||||
}
|
||||
data.update(my_context)
|
||||
await consumer.send_html(data)
|
||||
#+END_SRC
|
||||
|
||||
There are several points in the above code to keep in mind.
|
||||
|
||||
- ~template~ is the name of the template that will be rendered.
|
||||
- ~get_context()~ is a function that returns a dictionary with the context of the page.
|
||||
- ~send_page()~ is the function that will be executed when the page is loaded.
|
||||
- ~random_number()~ is the function that will be executed when the button is clicked.
|
||||
|
||||
** 7. Create the base template
|
||||
|
||||
Now we will create the base template, which will be the one that will be rendered when the page is loaded.
|
||||
|
||||
Create a folder called ~templates~, or use your template folder, inside your App and inside it create another folder called ~layouts~. Now create a file called ~base.html~.
|
||||
|
||||
#+BEGIN_SRC html
|
||||
{# my-app/templates/layouts/base.html #}
|
||||
{% load static i18n %}
|
||||
<!doctype html>{% get_current_language as CURRENT_LANGUAGE %}
|
||||
<html lang="{{ CURRENT_LANGUAGE }}">
|
||||
<head>
|
||||
<meta charset="utf-8">
|
||||
<title>{{ title }}</title>
|
||||
<meta
|
||||
name="viewport"
|
||||
content="width=device-width, initial-scale=1.0, shrink-to-fit=no"
|
||||
>
|
||||
<meta
|
||||
name="description"
|
||||
content="{{ meta.description }}"
|
||||
>
|
||||
<meta
|
||||
property="og:image"
|
||||
content="{{ meta.image }}"
|
||||
>
|
||||
<script type="module" src="{% static 'js/main.js' %}" defer></script>
|
||||
</head>
|
||||
<body
|
||||
data-host="{{ request.get_host }}"
|
||||
data-debug="{{ DEBUG }}"
|
||||
>
|
||||
<section id="loading"></section>
|
||||
<section id="notifications" class="notifications"></section>
|
||||
<section id="no_connection"></section>
|
||||
<div class="container">
|
||||
<header id="content-header">
|
||||
{% include 'components/header.html' %}
|
||||
</header>
|
||||
<main id="main" class="main-container">{% include page %}</main>
|
||||
<footer id="content-footer">
|
||||
{% include 'components/footer.html' %}
|
||||
</footer>
|
||||
</div>
|
||||
</body>
|
||||
</html>
|
||||
#+END_SRC
|
||||
|
||||
In the future we will define ~main.js~, a minimal JavaScript to connect the events and the WebSockets client.
|
||||
|
||||
** 8. Create the page template
|
||||
|
||||
We will create the home page template, which will be the one that will be rendered when the page is loaded.
|
||||
|
||||
Create a folder called ~pages~ in your template folder and inside it create a file called ~home.html~.
|
||||
|
||||
#+BEGIN_SRC html
|
||||
{# my-app/templates/pages/home.html #}
|
||||
{% load static %}
|
||||
|
||||
<main data-controller="home">
|
||||
<p>
|
||||
<button data-action="click->home#randomNumber">Random number</button>
|
||||
</p>
|
||||
<h2 id="output-random-number"></h2>
|
||||
</main>
|
||||
#+END_SRC
|
||||
|
||||
As you can see, we have defined a button to launch the action of generating the random number (~button~) and the place where we will print the result (~output-random-number~).
|
||||
|
||||
** 9. Create frontend
|
||||
|
||||
Now we are going to create the frontend, the part where we will manage the JavaScript events and invoke the actions.
|
||||
|
||||
Download [[https://github.com/Django-LiveView/assets/archive/refs/heads/main.zip][assets]] and unzip it in your static folder. You will be left with the following route: ~/static/js/~.
|
||||
|
||||
** 10. Create View
|
||||
|
||||
We will create the view that will render the page for the first time (like Server Side Rendering). The rest of the times will be rendered dynamically (like Single Page Application).
|
||||
|
||||
In a normal Django application we would create a view, ~views.py~, similar to the following:
|
||||
|
||||
#+BEGIN_SRC python
|
||||
# my-app/views.py
|
||||
from django.shortcuts import render
|
||||
|
||||
# Create your views here.
|
||||
def home(request):
|
||||
return render(request, "pages/home.html")
|
||||
#+END_SRC
|
||||
|
||||
With LiveView, on the other hand, you will have the following structure.
|
||||
|
||||
#+BEGIN_SRC python
|
||||
# my-app/views.py
|
||||
from django.shortcuts import render
|
||||
from .actions.home import get_context as get_home_context
|
||||
|
||||
from liveview.utils import get_html
|
||||
|
||||
async def home(request):
|
||||
return render(request, "layouts/base.html", await get_home_context())
|
||||
#+END_SRC
|
||||
|
||||
** 11. Create URL
|
||||
|
||||
Finally, we will create the URL that will render the page.
|
||||
|
||||
#+BEGIN_SRC python
|
||||
# my-app/urls.py
|
||||
from django.urls import path
|
||||
|
||||
from .views import home
|
||||
|
||||
urlpatterns = [
|
||||
path("", home, name="home"),
|
||||
]
|
||||
#+END_SRC
|
||||
|
||||
** 12. Run the server
|
||||
|
||||
Run the server.
|
||||
|
||||
#+BEGIN_SRC sh
|
||||
python manage.py runserver
|
||||
#+END_SRC
|
||||
|
||||
And open the browser at ~http://localhost:8000/~. You should see the home page with a button that generates a random number.
|
||||
|
||||

||||
