Question

Accepted Answer

**Django Template Language (DTL)** ana bukatuwa ne don samar da HTML cikin sauri — templates su ne fayilolin HTML da suna da special syntax don saka data, jiyowa, da yanayi. A niyya ne kawai ya damje logic a cikin templates, da hade presentation waje daga business logic (wanda ya kamata a templates views). ## Manyan syntaxes guda uku ```html

Author: {{ article.author.name }}

{% if user.is_authenticated %}

Welcome, {{ user.username }}

{% else %} Log in {% endif %} {% for article in articles %}

{% empty %}

No articles yet.

{% endfor %} {{ name|upper }} {{ article.body|truncatewords:30 }} {{ price|floatformat:2 }} {{ date|date:"Y-m-d" }} ``` Variables (`{{ }}`) suna fitarwa data, tags (`{% %}`) suna bada logic, da filters (`|`) suna canja values don nuni. ## Template inheritance — abubuwan makilaci don DRY layouts ```html {% block title %}My Site{% endblock %} {% block content %}{% endblock %} ``` ```html {% extends "base.html" %} {% block title %}Articles{% endblock %} {% block content %} {% for a in articles %}

{% endfor %} {% endblock %} ``` **Template inheritance** (`{% extends %}` + `{% block %}`) yana ba ka damar bayyana daidaitaccen layout sau daya (nav, footer, structure) da kuma yara templates za su cika sassa musamman — kaida haka sai ba ka maimaita page shell akan kowane shafi (DRY). ## Auto-escaping yana kariya tare da XSS (security) ```html {{ user_input }} {{ trusted|safe }} ``` A tsayi, Django **auto-escapes** fitarwa variable, da jawo HTML/script injection — ** XSS protection** da jita dole ne ka yi da hannu. ## Deliberately limited logic ```text DTL intentionally restricts logic (no arbitrary Python) → forces business logic into VIEWS, keeping templates focused on presentation. This separation is a feature. ``` ## Me yake mahalaci Django template language shi ne yadda kake samar da dynamic HTML, wanda ya zama mahimmanci ga kowane server-rendered Django app. Janye syntax — variables (`{{ }}`) don fitarwa data, tags (`{% %}`) don jiyowa da yanayi, da filters (`|`) don gyara — shine yau da kullun kida don gina shafuka. Gidia abubuwa ne mahimmanci sosai. Na farko, **template inheritance** (`{% extends %}` da `{% block %}`) shi ne karfi DRY feature wanda ya ba ka damar bayyana common layout na shafi sau daya da kuma shafuka na musamman za su cika sassan musamman, kaida haka sai ba ka maimaita page shell — wata jinjina a tare don tsara templates a ayyukan gaske. Na biyu, **automatic HTML escaping** yana ba da ** XSS protection** (babbar security fa'ida) ta jawo injected scripts a cikin data na mai amfani a tsayi, wanda ka dole ne ka tuna don yi da hannu a systems da yawa. DTL's deliberately limitation na logic shima yana kogara good separation na concerns ta hawo business logic a views. Sanin template syntax, inheritance, auto-escaping, da presentation/logic separation shine abubuwan mahalaci don gina sustainable, secure server-rendered Django apps.
