Python Programming: Your First Django Web Application

activate your virtual environment, install django via a requirements file, create a django project in src, then run the server to launch your first django app with sqlite

Create a Django view in views.py that returns an HttpResponse saying Hello world, then map it to a URL to render a custom home page and explore the Django admin.

Map URLs to a Django view and assign the home page to an empty path to render a hello world response, then note trailing slash behavior and redirects.

Create a templates folder beside manage.py and render index.html with Django's render, using a templates path and the request argument; configure Pathlib-based templates in settings.

Learn to use Django template inheritance by creating base.html and home.html, extending base, and replacing blocks with content using extends, block, and block.super, then render via views and URLs.

Explore how Django renders templates with context variables, using f strings and dictionaries to substitute values in Home.html, create reusable A, B, C pages, and apply Bootstrap for responsive styling.

Learn to integrate Bootstrap 5.2 into a Django project by using template inheritance and the include tag to modularize base, nav bar, CSS, and JavaScript, improving page styling and responsiveness.

Create and render your first Django form to collect user data on the landing page, starting with an email field, and learn to handle post requests and CSRF protection.

Learn how to validate data with Django forms by processing request.post or none and using form.is_valid and cleaned_data. Implement field and non-field errors, custom email validation, and confirm email matching.

Style Django forms by applying bootstrap form-control classes to all fields using an init method, iterating over self.fields, updating widgets and attributes, and optionally exploring Django crispy forms for layouts.

Refactor a Django project by turning views and forms into a dedicated app component called landing_pages using snake_case, configure imports and urls, and prepare to add models by updating settings.

Create your first Django model and map form data to a SQLite database, validate the email with form clean methods, and store as a landing page entry.

Create and apply django migrations to translate models into sql tables, manage database changes with make migrations and migrate, and understand automatic id fields and sqlite usage.

Learn to manage data with the Django admin by creating a super user, migrating the database, and registering a landing page entry model with display and search features.

Save form data to a landing page entry model in a Django view by creating an object or using objects.create, then save to persist the data.

Create a Django ModelForm that merges the landing page entry model with form fields, using a meta class to specify name and email and enabling save via form.save.

Modify a Django model by making fields optional with blank=true and adding a date time field for timestamps, then run make migrations and migrate.

Learn how to write an automated Django test with manage.py test, validate inactive items using query sets and filters, and explore fixtures and migrations to safeguard your landing page data.

Leverage Django fixtures to dump data and load data into a test database via manage.py, enabling fixtures-based testing with app-specific data.

Define a Django view to list database items by querying all objects, pass them as object_list to list.html, and render via a dedicated URL pattern for end users.

Attach a notes field to the landing page entry model, migrate, and filter entries by the logged-in user to secure content; leverage request.user in views and templates.

Learn to implement a dynamic landing page entry detail view in Django by routing a path with id to a detail view and rendering the item in a detail template.

Refactor Django forms with a bootstrap form mixin to reduce repetition, create a model form for notes, bind it to an entry instance, and use get_absolute_url with HttpResponseRedirect for saves.

Learn how to use Django's messages framework to show short-lived notifications after form submissions, render them in templates with bootstrap alerts, and tune with tags and dismissible alerts.

Master bootstrap layouts with container and container-fluid, rows and columns, and breakpoints to control wrapping and alignment. Use margins, padding, and auto margins to center content on the landing page.

Polish the landing page by integrating a Bootstrap hero, a responsive video, and a sign-up form into a fluid grid using rows, columns, and ratios.

Celebrate completing the series and your first django project. Plan your next steps by identifying questions about get_absolute_url and auto path creation, explore the django documentation, and build another project.
