Common Mistakes

Using folder paths in template_name incorrectly

Setting context_object_name to the model class name instead of a string

The template_name is usually the HTML file name, and context_object_name is the variable name used in the template to access the object.

💡 Hint

Common Mistakes

Calling the wrong super method

Not returning the context dictionary

Forgetting to set the template_name

To add extra data to the template, override get_context_data, call the parent method, add your data to the context dictionary, and return it. The template name is set as usual.
