What is the output of this Django template snippet?

Given the following Django template code, what will be the rendered HTML output assuming STATIC_URL = '/static/' and the static file css/style.css exists?

{% load static %}
<link rel="stylesheet" href="{% static 'css/style.css' %}">

Django

{% load static %}
<link rel="stylesheet" href="{% static 'css/style.css' %}">

A <link rel="stylesheet" href="/static/css/style.css">

B <link rel="stylesheet" href="static/css/style.css">

C <link rel="stylesheet" href="/css/style.css">

D <link rel="stylesheet" href="/assets/css/style.css">

💡 Hint

Remember that {% static %} prepends the STATIC_URL setting to the file path.

The {% static %} tag generates the full URL by combining STATIC_URL and the given path. Since STATIC_URL is '/static/', the output is '/static/css/style.css'.

Which option correctly loads and uses a static image in a Django template?

Select the Django template code snippet that correctly loads the static tag and displays an image located at images/logo.png.

A

{% load staticfiles %}
<img src="static 'images/logo.png'" alt="Logo">

B <img src="{% static 'images/logo.png' %}" alt="Logo">

C

{% load static %}
<img src="static('images/logo.png')" alt="Logo">

D

{% load static %}
<img src="{% static 'images/logo.png' %}" alt="Logo">

💡 Hint

You must load the static template tag library before using {% static %}.

Option D correctly loads the static tag library and uses the {% static %} tag with quotes around the path. Option D misses loading the tag library. Option D uses an outdated tag library and wrong syntax. Option D uses wrong syntax for the static tag.

Why does this Django template raise a TemplateSyntaxError?

Consider this Django template snippet:

{% load static %}
<img src="{% static images/logo.png %}" alt="Logo">

Why does it raise a TemplateSyntaxError?

Django

{% load static %}
<img src="{% static images/logo.png %}" alt="Logo">

A Because the static tag requires parentheses around the path.

B Because the static tag cannot be used inside an img tag.

C Because the static tag argument must be a quoted string, but here it is unquoted.

D Because the static tag must be loaded after the img tag.

💡 Hint

Check how the path argument is passed to the static tag.

The static tag requires its argument to be a quoted string. Omitting quotes causes a TemplateSyntaxError.

What is the value of the rendered src attribute in this Django template?

Given STATIC_URL = '/assets/' in settings.py, what will be the value of the src attribute after rendering this template?

{% load static %}
<img src="{% static 'img/photo.jpg' %}" alt="Photo">

Django

{% load static %}
<img src="{% static 'img/photo.jpg' %}" alt="Photo">

A img/photo.jpg

B /assets/img/photo.jpg

C /static/img/photo.jpg

D /media/img/photo.jpg

💡 Hint

The static tag uses the STATIC_URL setting as prefix.

Since STATIC_URL is set to '/assets/', the static tag outputs '/assets/img/photo.jpg'.

🧠 Conceptual

Which statement about Django static files in templates is TRUE?

Choose the correct statement about using static files in Django templates.

A The {% static %} tag must be loaded with {% load static %} before use, and it generates URLs based on STATIC_URL setting.

B Static files can be referenced directly without loading any tag, and Django automatically resolves their URLs.

C The {% static %} tag requires the full absolute URL including domain to work correctly.

D Static files must be placed inside the templates directory to be accessible via {% static %}.

💡 Hint

Think about how Django manages static files and the role of the static template tag.

Option A correctly describes that {% static %} requires loading the static tag library and uses STATIC_URL to build URLs. Other options are incorrect because Django does not resolve static URLs automatically without the tag, does not require full URLs, and static files should be in static directories, not templates.

Practice

1. What is the purpose of using {% load static %} at the beginning of a Django template?

easy

A. To start a for loop in the template

B. To load dynamic content from the database

C. To include another template inside the current one

D. To enable the use of static files like images, CSS, and JavaScript in the template

Solution

1. Step 1: Understand the role of static files in Django templates

   Static files are images, CSS, and JavaScript that enhance the website's appearance and behavior.

2. Step 2: Recognize the function of {% load static %}

   This tag loads the static template tag library, enabling the use of {% static %} to reference static files correctly.

3. Final Answer:

   To enable the use of static files like images, CSS, and JavaScript in the template -> Option D

4. Quick Check:

   Load static = enable static files [OK]

Hint: Remember: load static must be at the top to use static files [OK]

Common Mistakes:

• Forgetting to add {% load static %} before using {% static %}
• Confusing static files with dynamic content
• Using {% load static %} in views instead of templates

2. Which of the following is the correct syntax to include a CSS file named styles.css located in the static folder inside a Django template?

easy

A.

B.

C.

D.

Solution

1. Step 1: Recall the correct way to reference static files in Django templates

   Use the {% static 'path/to/file' %} tag after loading static files with {% load static %}.

2. Step 2: Identify the correct syntax for linking CSS

   The correct syntax uses {% static 'styles.css' %} inside the href attribute.

3. Final Answer:

   <link href="{% static 'styles.css' %}" rel="stylesheet"> -> Option A

4. Quick Check:

   Use {% static 'file' %} for static URLs [OK]

Hint: Use {% static 'file' %} inside href for static files [OK]

Common Mistakes:

• Using raw paths without {% static %} tag
• Using {{ static() }} which is invalid
• Trying to load static inside the href attribute

3. Given the template code below, what will be the rendered HTML output if the static file URL for images/logo.png is /static/images/logo.png?

{% load static %}

medium

A.

B.

C.

D.

Solution

1. Step 1: Understand the role of {% static %} tag

   The {% static %} tag converts the file path into the correct URL for static files, here it becomes /static/images/logo.png.

2. Step 2: Determine the final rendered HTML

   The template renders the img tag with src set to the static URL, so the output is <img src="/static/images/logo.png" alt="Logo">.

3. Final Answer:

   <img src="/static/images/logo.png" alt="Logo"> -> Option B

4. Quick Check:

   Static tag outputs correct URL [OK]

Hint: Static tag outputs full static URL in rendered HTML [OK]

Common Mistakes:

• Expecting the template tag to appear in output
• Confusing static URL with media URL
• Omitting {% load static %} causing errors

4. You wrote this Django template code to include a JavaScript file but it does not load correctly:

{% load static %}

What is the error and how can you fix it?

medium

A. Missing {% load static %} tag; add it at the top

B. Wrong file path; fix by changing src to /static/js/app.js

C. Missing {% static %} tag; fix by changing src to {% static 'js/app.js' %}

D. JavaScript files cannot be loaded this way in Django

Solution

1. Step 1: Identify the incorrect static file reference

   The src attribute uses a raw path "static/js/app.js" without the {% static %} tag, so Django won't resolve it correctly.

2. Step 2: Correct the syntax to use {% static %} tag

   Use src="{% static 'js/app.js' %}" to let Django generate the correct URL.

3. Final Answer:

   Missing {% static %} tag; fix by changing src to {% static 'js/app.js' %} -> Option C

4. Quick Check:

   Use {% static %} for static file URLs [OK]

Hint: Always wrap static file paths with {% static 'path' %} [OK]

Common Mistakes:

• Using raw paths without {% static %}
• Forgetting to load static tag
• Assuming /static/ prefix works automatically

5. You want to include an image and a CSS file in your Django template. The image is at images/photo.jpg and the CSS file is at css/style.css inside your static folder. Which template code correctly includes both files?

hard

A. {% load static %}

B. {% load static %}

C.

D. {% load static %}

Solution

1. Step 1: Ensure {% load static %} is included at the top

   This is required to use the {% static %} tag in the template.

2. Step 2: Use {% static %} tag to reference both image and CSS files

   Both src and href attributes must use {% static 'path' %} to generate correct URLs.

3. Final Answer:

   {% load static %} <img src="{% static 'images/photo.jpg' %}" alt="Photo"> <link rel="stylesheet" href="{% static 'css/style.css' %}"> -> Option A

4. Quick Check:

   Load static + use {% static %} for all static files [OK]

Hint: Always load static and use {% static 'file' %} for all static files [OK]

Common Mistakes:

• Omitting {% load static %} tag
• Using raw paths without {% static %}
• Mixing static and media URLs
