Practice - 5 Tasks

1fill in blank

easy

Complete the code to set the URL prefix for static files in Django settings.

Django

STATIC_URL = '[1]'

Drag options to blanks, or click blank then click option'

A/media/

B/static/

C/assets/

D/files/

💡 Hint

Common Mistakes

Using '/media/' which is for user-uploaded files, not static files.

Omitting the trailing slash which can cause URL issues.

The STATIC_URL setting defines the URL prefix where static files are served. The common default is /static/.

Complete the code to add a directory named 'assets' inside the project root to the static files directories.

Django

STATICFILES_DIRS = [BASE_DIR / '[1]']

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Confusing 'media' with static files directory.

Using a folder name that does not exist in the project.

The STATICFILES_DIRS setting is a list of folders where Django will look for additional static files. Here, we add the 'assets' folder.

Fix the error in the STATICFILES_DIRS setting to correctly include the 'static' folder inside the project root.

Django

STATICFILES_DIRS = [BASE_DIR [1] 'static']

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using '+' which concatenates strings but does not work with Path objects.

Using '*' or '-' which are invalid for path joining.

To join paths in Django settings using pathlib, use the division operator / to combine BASE_DIR with folder names.

4fill in blank

hard

Fill both blanks to create a STATICFILES_DIRS list with two folders: 'assets' and 'extra_static' inside the project root.

Django

STATICFILES_DIRS = [BASE_DIR / '[1]', BASE_DIR / '[2]']

Drag options to blanks, or click blank then click option'

Aassets

Bextra_static

💡 Hint

Common Mistakes

Including 'media' which is not for static files.

Using folder names that do not exist.

This setting tells Django to look for static files in both 'assets' and 'extra_static' folders inside the project root.

5fill in blank

hard

Fill all three blanks to set STATIC_URL to '/static/', and include 'static' and 'assets' folders in STATICFILES_DIRS inside the project root.

Django

STATIC_URL = '[1]'
STATICFILES_DIRS = [BASE_DIR / '[2]', BASE_DIR / '[3]']

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mixing up '/media/' with '/static/' for STATIC_URL.

Including wrong folder names in STATICFILES_DIRS.

The STATIC_URL is set to /static/ which is the URL prefix for static files. The STATICFILES_DIRS includes the 'static' and 'assets' folders inside the project root.

Practice

1. What is the purpose of STATIC_URL in a Django project?

easy

A. It sets the database connection string for static files.

B. It defines the URL prefix to access static files in the browser.

C. It lists the directories where static files are stored on disk.

D. It configures the caching behavior for static files.

Solution

1. Step 1: Understand STATIC_URL role

   STATIC_URL is used to tell Django what URL prefix to use when serving static files like images or CSS.

2. Step 2: Differentiate from STATICFILES_DIRS

   STATICFILES_DIRS lists folders on disk, not URLs. The other options are unrelated to URL prefix.

3. Final Answer:

   It defines the URL prefix to access static files in the browser. -> Option B

4. Quick Check:

   STATIC_URL = URL prefix [OK]

Hint: STATIC_URL is the web address prefix for static files [OK]

Common Mistakes:

• Confusing STATIC_URL with STATICFILES_DIRS
• Thinking STATIC_URL sets file system paths
• Assuming STATIC_URL controls caching

2. Which of the following is the correct way to define STATICFILES_DIRS in Django settings?

easy

A. STATICFILES_DIRS = 'staticfiles'

B. STATICFILES_DIRS = '/static/'

C. STATICFILES_DIRS = [BASE_DIR / 'static']

D. STATICFILES_DIRS = {'static': BASE_DIR}

Solution

1. Step 1: Recognize STATICFILES_DIRS type

   It must be a list or tuple of folder paths, not a string or dict.

2. Step 2: Check syntax correctness

   STATICFILES_DIRS = [BASE_DIR / 'static'] uses a list with a path expression (BASE_DIR / 'static'), which is correct syntax in modern Django.

3. Final Answer:

   STATICFILES_DIRS = [BASE_DIR / 'static'] -> Option C

4. Quick Check:

   STATICFILES_DIRS is a list of folders [OK]

Hint: STATICFILES_DIRS must be a list of folder paths [OK]

Common Mistakes:

• Using a string instead of a list
• Using a dictionary instead of a list
• Forgetting to use BASE_DIR or full path

3. Given the settings:

STATIC_URL = '/assets/'
STATICFILES_DIRS = [BASE_DIR / 'assets']

What URL will Django use to serve a file named logo.png located inside the assets folder?

medium

A. /static/logo.png

B. /static/assets/logo.png

C. /assets/assets/logo.png

D. /assets/logo.png

Solution

1. Step 1: Understand STATIC_URL usage

   STATIC_URL sets the URL prefix for static files. Here it is '/assets/'.

2. Step 2: Map file location to URL

   The file 'logo.png' inside the 'assets' folder will be served at '/assets/logo.png' because STATICFILES_DIRS points to that folder.

3. Final Answer:

   /assets/logo.png -> Option D

4. Quick Check:

   URL = STATIC_URL + filename [OK]

Hint: URL = STATIC_URL + filename path [OK]

Common Mistakes:

• Adding folder name twice in URL
• Using default '/static/' URL instead of custom
• Confusing file system path with URL path

4. You set STATICFILES_DIRS = BASE_DIR / 'static' without brackets in Django settings. What error will occur?

medium

A. TypeError because STATICFILES_DIRS must be a list or tuple

B. No error, it works fine

C. SyntaxError due to missing quotes

D. FileNotFoundError at runtime

Solution

1. Step 1: Check STATICFILES_DIRS expected type

   It must be a list or tuple of paths, not a single path object.

2. Step 2: Analyze given assignment

   Assigning a single path without brackets makes it a path object, not a list, causing a TypeError.

3. Final Answer:

   TypeError because STATICFILES_DIRS must be a list or tuple -> Option A

4. Quick Check:

   STATICFILES_DIRS needs list/tuple [OK]

Hint: Always wrap STATICFILES_DIRS paths in a list or tuple [OK]

Common Mistakes:

• Forgetting brackets around STATICFILES_DIRS paths
• Assuming single path is accepted
• Confusing syntax error with runtime error

5. You want to serve static files from two folders: assets and common_static inside your project. How should you configure STATICFILES_DIRS and STATIC_URL to serve files correctly under the URL prefix /static/?

hard

A. STATIC_URL = '/static/'
STATICFILES_DIRS = [BASE_DIR / 'assets', BASE_DIR / 'common_static']

B. STATIC_URL = '/assets/'
STATICFILES_DIRS = [BASE_DIR / 'static', BASE_DIR / 'common_static']

C. STATIC_URL = '/static/'
STATICFILES_DIRS = BASE_DIR / 'assets' + BASE_DIR / 'common_static'

D. STATIC_URL = '/common_static/'
STATICFILES_DIRS = [BASE_DIR / 'assets']

Solution

1. Step 1: Set STATIC_URL to desired URL prefix

   To serve all static files under '/static/', set STATIC_URL = '/static/'.

2. Step 2: List all static folders in STATICFILES_DIRS

   Include both folders as a list: [BASE_DIR / 'assets', BASE_DIR / 'common_static'] so Django finds files in both.

3. Step 3: Avoid incorrect concatenation or mismatched URLs

   Concatenating paths or mismatching URL prefixes causes errors or missing files.

4. Final Answer:

   STATIC_URL = '/static/' STATICFILES_DIRS = [BASE_DIR / 'assets', BASE_DIR / 'common_static'] -> Option A

5. Quick Check:

   Multiple folders in list, one URL prefix [OK]

Hint: Use list for multiple folders, one STATIC_URL prefix [OK]

Common Mistakes:

• Concatenating paths instead of listing them
• Using different URL prefixes for folders
• Forgetting to include all folders in list
