Hooking up the URL mapper
The website is created with a URL mapper file (urls.py) in the project folder. While you can use this file to manage all your URL mappings, it is more usual to defer mappings to the associated application.
"""locallibrary URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/3.1/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path
urlpatterns = [
path('admin/', admin.site.urls),
]
Django does not serve static files like CSS, JavaScript, and images by default, but it can be useful for the development web server to do so while you're creating your site. As a final addition to this URL mapper, you can enable the serving of static files during development by appending the following lines.
# Use static() to add url mapping to serve static files during development (only)
from django.conf import settings
from django.conf.urls.static import static
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
Testing the website framework
When we created the website, Django automatically added a number of models for use by the admin section of the site (which we'll look at later). Run the following commands to define tables for those models in the database (make sure you are in the directory that contains manage.py):
python3 manage.py makemigrations
python3 manage.py migrate
The makemigrations command creates (but does not apply) the migrations for all applications installed in your project. You can specify the application name as well to just run a migration for a single project. This gives you a chance to check out the code for these migrations before they are applied. If you're a Django expert, you may choose to tweak them slightly!
