Django Practice

Products lose data: prices come back wrong, names have no length limit, and nothing records when an item was added. Define a Product model with a bounded name, an exact decimal price, a stock count with a sensible default, an active flag, an auto-set creation time and a readable string form.

Books and authors live in unrelated tables, so deleting an author leaves orphaned books. Relate Book to Author so an author's books go with the author and are listed through the author, and add an optional publisher that cannot be deleted while it still has books.

Students take many courses, courses have many students, and each student has exactly one transcript. Model the many-to-many and the one-to-one, readable from both sides, with at most one transcript per student enforced by the database.

The product search returns everything no matter what the user asks for. Filter products by a case-insensitive name match and an inclusive price range, leave out inactive items, sort by price then name, and answer in a single database query.

A report needs items in the right order, only a few columns, and just the latest rows. Add chainable QuerySet methods that sort by name or newest first, take the top N, and return plain dicts or a flat list of names.

Detail lookups crash on unknown products and silently pick a random row when names repeat. Fetch single products safely by sku and by name, ignore discontinued items, and answer "any products?" and "how many?" without loading rows.

Only the home page is routed, so every article URL is a 404. Route articles by id, slug and four-digit year so the view receives typed values and malformed URLs are rejected before any view runs.

Links and redirects break every time a URL changes. Name the routes inside an app namespace, build every link from those names, and send old post URLs to their new home with a permanent redirect.

Product pages need a safe detail view and a JSON endpoint. Return the product page or a 404 for unknown ids, and serve the same product as properly encoded JSON with its price as a two-decimal string.

The product page has no template yet. Render the product from a template with a readable release date, a fallback for a missing manufacturer, a short description teaser and prices that always show two decimals.

Every product row in the listing looks the same. Number the rows, alternate their styling, show a sold-out or low-stock badge from a reusable partial, and show a friendly message when the list is empty.

Every page would need its own copy of the HTML skeleton and navbar. Build a base template with title and content blocks and an included navbar whose links come from URL names, then have each page extend it.

Register the catalogue models with the Django admin so staff can create, edit and delete records through the interface.

Configure a Django admin change list with columns, a computed column, search, sidebar filters and a default order.

Edit order items inline on the order page, show a read-only computed total and add a bulk admin action.

Serve a stylesheet and a logo through Django's static files: the app static layout and the static template tag instead of hardcoded paths.

Accept a validated PDF upload through a Django form and store it under MEDIA_ROOT, with the multipart encoding the browser needs.

Add an image field with an upload-to path and render the stored image's URL, falling back to a static placeholder.

Configure a Django ListView with its template, context name, ordering and built-in pagination.

Wire a DetailView and a CreateView with a form class, redirecting to the new object through get_absolute_url.

Restrict UpdateView and DeleteView to the signed-in user's own objects by overriding get_queryset, with login required and defined redirects.
