How to display a variable's value in a Django template?
Risposta
Double curly braces {{ variable }} are used to display the value of a variable passed to the template context. Django automatically escapes HTML to prevent XSS attacks. The variable name must exactly match a key in the context dictionary provided by the view.
2What is the role of template tags in Django?
What is the role of template tags in Django?
Risposta
Template tags allow executing logic in templates: loops, conditions, including other templates, and more. They use the {% tag %} syntax and some require a closing tag like {% endfor %} or {% endif %}. They provide programming power while maintaining separation between business logic and presentation.
3How to use the {% for %} tag to iterate over a list of objects?
How to use the {% for %} tag to iterate over a list of objects?
Risposta
The {% for item in list %} syntax allows iterating over each element in a list. Inside the block, the item variable contains the current element. The {% endfor %} tag marks the loop's end. Django also provides special variables like forloop.counter, forloop.first, and forloop.last for iteration logic.
Which filter converts text to uppercase in a Django template?
How does template inheritance work with {% extends %}?
