All Modules & Topics in Django Training
Django 5 Overview — Batteries-Included Philosophy, DRY Principle, WSGI/ASGI & Built-In Security
Purpose: To understand and apply Django 5 Overview — Batteries-Included Philosophy, DRY Principle, WSGI/ASGI & Built-In Security in real Django systems — specifically: Why Instagram, Pinterest, Disqus, and Mozilla scaled on Django: built-in ORM, Migrations, Admin, Auth, Forms, Caching, and out-of-the-box defenses against **SQL Injection, XSS, CSRF, Clickjacking, and Host Header Poisoning** — plus dual `wsgi.py` & `asgi.py` entrypoints!, so your code stays reliable, fast, and easy to maintain in production.
Django MVT (`Model` - `View` - `Template`) Architecture vs Classic MVC & Full Request Lifecycle
Purpose: To understand and apply Django MVT (`Model` - `View` - `Template`) Architecture vs Classic MVC & Full Request Lifecycle in real Django systems — specifically: Mapping MVT to MVC accurately: Django’s **`Model`** = Data + Business Domain, Django’s **`Template`** = Presentation Layer (MVC’s "View"!), and Django’s **`View`** = Request Handler deciding *which* data is shown (MVC’s "Controller"!), while Django’s URL Dispatcher acts as the Front Controller!, so your code stays reliable, fast, and easy to maintain in production.
Virtual Environments (`venv` / `uv`), Installing Django 5, `django-admin` & `manage.py` CLI
Purpose: To understand and apply Virtual Environments (`venv` / `uv`), Installing Django 5, `django-admin` & `manage.py` CLI in real Django systems — specifically: Isolating per-project dependencies (`python -m venv .venv`), pinning deterministic versions (`pip freeze` / `requirements.lock` / `uv.lock`), and understanding why `python manage.py` wraps `django-admin` by pre-setting `DJANGO_SETTINGS_MODULE`!, so your code stays reliable, fast, and easy to maintain in production.
Django Project vs Reusable Apps (`startapp`) — `INSTALLED_APPS`, `AppConfig` & `DEFAULT_AUTO_FIELD`
Purpose: To understand and apply Django Project vs Reusable Apps (`startapp`) — `INSTALLED_APPS`, `AppConfig` & `DEFAULT_AUTO_FIELD` in real Django systems — specifically: A **Project** is the whole site configuration (`settings.py`, root `urls.py`, `asgi.py`), while an **App** (`python manage.py startapp catalog`) is a focused domain module (`models.py`, `views.py`, `admin.py`, `migrations/`, `tests.py`) registered in `INSTALLED_APPS`!, so your code stays reliable, fast, and easy to maintain in production.
Django URL Dispatcher — `urlpatterns`, `path()` Converters (`<int>`, `<slug>`, `<uuid>`), `include()` & Namespaces
Purpose: To understand and apply Django URL Dispatcher — `urlpatterns`, `path()` Converters (`<int>`, `<slug>`, `<uuid>`), `include()` & Namespaces in real Django systems — specifically: Top-to-bottom sequential matching in `urlpatterns`, built-in path converters (`int`, `str`, `slug`, `uuid`, `path`), delegating sub-trees via `path("courses/", include("catalog.urls"))`, `app_name` URL namespaces, and `reverse()` / `reverse_lazy()`, so your code stays reliable, fast, and easy to maintain in production.

Purpose: To understand and apply Function-Based Views (`FBV`) — `HttpRequest`, `HttpResponse`, `JsonResponse`, Decorators & `async def` Views in real Django systems — specifically: Writing explicit Python view functions `def detail(request: HttpRequest, slug: str) -> HttpResponse:`, HTTP verb guards (`@require_GET`, `@require_POST`, `@require_http_methods`), returning `JsonResponse({"items": [...]})`, and Django 5 native `async def` coroutine views!, so your code stays reliable, fast, and easy to maintain in production.
Class-Based Generic Views (`CBV`) — `ListView`, `DetailView`, `CreateView`, Mixins & MRO Order
Purpose: To understand and apply Class-Based Generic Views (`CBV`) — `ListView`, `DetailView`, `CreateView`, Mixins & MRO Order in real Django systems — specifically: Eliminating repetitive CRUD boilerplate via `View`, `TemplateView`, `ListView` (`paginate_by`), `DetailView`, `CreateView`, `UpdateView`, and `DeleteView`, overriding `get_queryset()` / `get_context_data()`, and `LoginRequiredMixin`!, so your code stays reliable, fast, and easy to maintain in production.
Django Shortcuts — `render()`, `get_object_or_404()`, `redirect()` & Open-Redirect Protection
Purpose: To understand and apply Django Shortcuts — `render()`, `get_object_or_404()`, `redirect()` & Open-Redirect Protection in real Django systems — specifically: Clean view ergonomics: `render(request, tpl, ctx, status=200)`, `get_object_or_404(Course.objects.filter(is_published=True), slug=slug)` (converting `DoesNotExist` into `Http404`!), `redirect("catalog:detail", slug=slug)`, and `url_has_allowed_host_and_scheme()`, so your code stays reliable, fast, and easy to maintain in production.
Django Template Language (`DTL`) — Inheritance, Tags, Filters, `json_script` & Auto-Escaping
Purpose: To understand and apply Django Template Language (`DTL`) — Inheritance, Tags, Filters, `json_script` & Auto-Escaping in real Django systems — specifically: Intentional logic-light DTL design (no arbitrary Python calls inside `{{ }}`!), layout inheritance (`{% extends "base.html" %}`), dot-lookup order (`dict[k]` -> `attr` -> `method()` -> `list[i]`), auto-escaping, and **`{{ value|json_script:"data-id" }}`**!, so your code stays reliable, fast, and easy to maintain in production.
Static Files in Production — `STATIC_URL`, `STATIC_ROOT`, `collectstatic` & `WhiteNoise` Caching
Purpose: To understand and apply Static Files in Production — `STATIC_URL`, `STATIC_ROOT`, `collectstatic` & `WhiteNoise` Caching in real Django systems — specifically: How `{% load static %}` + `{% static "css/app.css" %}` works, why `STATICFILES_DIRS` (extra source dirs) must NEVER equal `STATIC_ROOT` (compiled output target of `python manage.py collectstatic --noinput`!), and immutable MD5/SHA hash fingerprinting via `WhiteNoise` / CloudFront!, so your code stays reliable, fast, and easy to maintain in production.
Component Partials (`{% include ... only %}`), Custom `@register.simple_tag` & Responsive Form Styling
Purpose: To understand and apply Component Partials (`{% include ... only %}`), Custom `@register.simple_tag` & Responsive Form Styling in real Django systems — specifically: Modularizing Bootstrap 5 / Tailwind UIs with isolated `{% include "components/_badge.html" with label="Live" only %}`, building custom `templatetags/` (`@register.simple_tag`, `@register.filter`), and styling Django forms cleanly (`django-crispy-forms` / custom widget attrs), so your code stays reliable, fast, and easy to maintain in production.
Django Models (`models.Model`) — Field Types, `TextChoices`, `Meta.indexes` & `CheckConstraint`
Purpose: To understand and apply Django Models (`models.Model`) — Field Types, `TextChoices`, `Meta.indexes` & `CheckConstraint` in real Django systems — specifically: Mapping Python classes to SQL tables: `CharField`, `SlugField(unique=True)`, `DecimalField` (exact base-10 decimal!), Django 5 **`GeneratedField`** (database-computed columns!) & `db_default`, `models.TextChoices` enums, `Meta.indexes`, and `Meta.constraints`, so your code stays reliable, fast, and easy to maintain in production.
Relational Fields — `ForeignKey` (`related_name`), `ManyToManyField` (`through=`) & `OneToOneField`
Purpose: To understand and apply Relational Fields — `ForeignKey` (`related_name`), `ManyToManyField` (`through=`) & `OneToOneField` in real Django systems — specifically: Modeling `Many-to-One` (`ForeignKey` — Django automatically creates a B-Tree index on `course_id`!), `Many-to-Many` (`ManyToManyField` with explicit `through="Enrollment"` when extra columns like `enrolled_at` or `role` are needed!), and `OneToOneField`, so your code stays reliable, fast, and easy to maintain in production.
`on_delete` Referential Rules — `CASCADE` vs `PROTECT` vs `RESTRICT` vs `SET_NULL`
Purpose: To understand and apply `on_delete` Referential Rules — `CASCADE` vs `PROTECT` vs `RESTRICT` vs `SET_NULL` in real Django systems — specifically: Why Django 2.0+ made `on_delete` a **mandatory positional argument** on `ForeignKey` & `OneToOneField`: contrasting destructive `models.CASCADE`, safe financial/audit **`models.PROTECT`** / `models.RESTRICT`, `models.SET_NULL(null=True)`, and soft-deletion patterns, so your code stays reliable, fast, and easy to maintain in production.
Django Migrations & Production DB Connectivity — `makemigrations`, `RunPython` & `CONN_MAX_AGE`
Purpose: To understand and apply Django Migrations & Production DB Connectivity — `makemigrations`, `RunPython` & `CONN_MAX_AGE` in real Django systems — specifically: Generating declarative schema diffs (`makemigrations`), inspecting exact SQL (`sqlmigrate`), failing CI if model changes lack migrations (`makemigrations --check --dry-run`), writing historical `apps.get_model()` `RunPython` data migrations, and persistent DB connections (`CONN_MAX_AGE = 600` / `psycopg` pool!), so your code stays reliable, fast, and easy to maintain in production.

Purpose: To understand and apply Django ORM `QuerySet` Mastery — Lazy Chaining, `exists()`, `values_list()`, `annotate()` & `bulk_create()` in real Django systems — specifically: Composable `filter()`, `exclude()`, field lookups (`__icontains`, `__gte`, `__in`, `__date`), pushing math to SQL via `aggregate()` & `annotate(Count(...))`, memory-safe `.iterator(chunk_size=2000)`, `only()`/`defer()`, and `bulk_create()` / `bulk_update()`, so your code stays reliable, fast, and easy to maintain in production.
`select_related()` vs `prefetch_related()` — Crushing the Django ORM `N+1` Query Bottleneck
Purpose: To understand and apply `select_related()` vs `prefetch_related()` — Crushing the Django ORM `N+1` Query Bottleneck in real Django systems — specifically: The #1 Django interview & production performance topic: **`select_related("author", "category")`** performs a single SQL `LEFT/INNER JOIN` for forward `ForeignKey` & `OneToOneField`; **`prefetch_related("tags", Prefetch(...))`** runs a separate `WHERE id IN (...)` query and joins in Python for `ManyToMany` & reverse `ForeignKey`s!, so your code stays reliable, fast, and easy to maintain in production.
Atomic SQL with `F()` Expressions, Complex `Q()` Boolean Filters & `transaction.atomic()`
Purpose: To understand and apply Atomic SQL with `F()` Expressions, Complex `Q()` Boolean Filters & `transaction.atomic()` in real Django systems — specifically: Referencing database columns on the right-hand side of queries/updates with **`F("views") + 1`** (`filter(mrp__gt=F("discount_price"))`), combining `OR` / `NOT` conditions with **`Q(code="DJNG") | ~Q(is_archived=True)`**, and coordinating multi-step writes with `transaction.atomic()` + `on_commit()`, so your code stays reliable, fast, and easy to maintain in production.

Purpose: To understand and apply Multi-Stage Form Validation — `clean_<field>()`, Cross-Field `clean()` & `ValidationError` Codes in real Django systems — specifically: Execution order during `form.is_valid()`: `to_python()` -> `validate()` -> `run_validators()` -> **`clean_<fieldname>()`** -> **`form.clean()`** (for cross-field invariants like `end_date > start_date` or `discount_price <= price`!) -> `Model.post_clean()`, so your code stays reliable, fast, and easy to maintain in production.
Custom User Models (`AbstractUser` vs `AbstractBaseUser`) — Why `AUTH_USER_MODEL` Must Come First!
Purpose: To understand and apply Custom User Models (`AbstractUser` vs `AbstractBaseUser`) — Why `AUTH_USER_MODEL` Must Come First! in real Django systems — specifically: Official Django documentation’s #1 project-setup recommendation: create `class User(AbstractUser): pass` and set **`AUTH_USER_MODEL = "accounts.User"`** BEFORE your first `manage.py migrate`! Comparing `AbstractUser` (keeps username/first_name/permissions) vs `AbstractBaseUser` (minimal email-only login), so your code stays reliable, fast, and easy to maintain in production.
