Generic Class-Based Views for CRUD
Django's generic views provide ready-made CRUD operations - ListView, DetailView, CreateView, UpdateView, DeleteView. They handle common patterns with minimal code, reducing boilerplate and following Django conventions.

Generic CRUD Views
- ListView - List objects with pagination
- DetailView - Display single object
- CreateView - Form to create new object
- UpdateView - Form to edit existing object
- DeleteView - Confirm and delete object
- All generic views need model and template_name
- CreateView/UpdateView need fields or form_class
- DeleteView needs success_url

# ]?? Tip
Tip
Use form.save(commit=False) when you need to modify the object before saving (e.g., setting the author from request.user).

QuerySets are LAZY - no DB hit until evaluated.
?? Common Mistake
Warning
Calling form.save() without checking form.is_valid() first. Always validate before saving to the database.
?? Practice Task
Note
(1) Use commit=False to set author. (2) Save with form.save(). (3) Add success message with Django messages.
