Django provides built-in password reset views. I customize templates to match site design. The flow sends a secure token via email that expires after a timeout. I configure email backend and PASSWORD_RESET_TIMEOUT in settings. For better UX, I customi

Proper logging is critical for production debugging. I configure loggers for different apps and libraries. I use file handlers for persistence and console handlers for development. Log rotation prevents disk fill-up. I set appropriate levels (DEBUG, I

Window functions perform calculations across rows related to the current row. I use them for running totals, rankings, and moving averages. Django's Window expression with functions like RowNumber, Rank, DenseRank provide SQL window function support.

Sessions store user state across requests. Django supports database, cache, file, and cookie-based sessions. I use cacheddb for read performance with database persistence. For APIs, I avoid sessions in favor of token auth. The request.session dict-lik

URL namespaces prevent name collisions across apps. I set app_name in app-level urls.py and use namespace in include(). Reverse lookups use reverse('namespace:name') or {% url 'namespace:name' %} in templates. This makes URLs maintainable when refacto

Formsets handle multiple forms on one page. I use modelformset_factory for editing existing objects and inlineformset_factory for related objects. The extra parameter controls empty forms shown. I validate formsets with formset.is_valid() and save wit

Soft deletes mark records as deleted without removing them from the database. I add a deleted_at field and override the delete() method. A custom manager excludes soft-deleted records by default. I provide a hard_delete() method for permanent removal.

JWT tokens provide stateless authentication for APIs. I use djangorestframework-simplejwt for token generation and validation. The TokenObtainPairView issues access and refresh tokens on login. I configure token lifetimes in settings. For protected en

Generic class-based views reduce boilerplate for standard CRUD operations. I use ListView, DetailView, CreateView, UpdateView, and DeleteView. Setting model and template_name is often sufficient. For create/update views, I specify fields or form_class

I send HTML emails using Django templates for consistent branding. The EmailMultiAlternatives class supports both plain text and HTML versions. I render templates with render_to_string and context data. For transactional emails, I queue them via Celer

For queries too complex for the ORM, I use raw SQL. The raw() method returns model instances. I use cursor.execute() for non-model queries. I always use parameterized queries to prevent SQL injection—never string interpolation. For reporting, raw SQL

Indexes dramatically improve query performance. I add indexes via Meta.indexes or db_index=True on frequently-filtered fields. Compound indexes help queries filtering on multiple fields. For text search, I use GinIndex on PostgreSQL. I index foreign k
