Practice - 5 Tasks

1fill in blank

💡 Hint

Common Mistakes

Using '/static/' instead of '/media/' for MEDIA_URL

Forgetting the trailing slash in the URL

The MEDIA_URL setting defines the base URL for media files uploaded by users. It usually ends with a slash, like /media/.

Complete the code to set the filesystem path where Django will store uploaded media files.

Django

MEDIA_ROOT = os.path.join(BASE_DIR, '[1]')

💡 Hint

Common Mistakes

Using 'static' folder for MEDIA_ROOT instead of 'media'

Not joining the path with BASE_DIR

The MEDIA_ROOT setting defines the absolute filesystem path where uploaded media files are saved. It is common to name this folder 'media'.

Fix the error in this Django settings snippet to correctly serve media files during development.

Django

urlpatterns += static(settings.[1], document_root=settings.MEDIA_ROOT)

💡 Hint

Common Mistakes

Using STATIC_URL instead of MEDIA_URL

Confusing MEDIA_ROOT and MEDIA_URL in the static() function

When serving media files in development, you use static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) to map the URL to the filesystem path.

4fill in blank

Fill both blanks to create a dictionary comprehension that maps filenames to their full media paths.

Django

file_paths = {filename: os.path.join(settings.[1], filename) for filename in file_list if filename.endswith([2])}

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

C'.png'

💡 Hint

Common Mistakes

Using MEDIA_URL instead of MEDIA_ROOT for file paths

Using wrong file extension filter

This comprehension builds a dictionary where each filename ending with '.jpg' is mapped to its full path inside MEDIA_ROOT.

5fill in blank

hard

Fill all three blanks to define a Django view that returns the URL of an uploaded media file.

Django

def get_media_url(filename):
    return settings.[1] + [2] + filename + [3]

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

AMEDIA_URL

B'/'

C''

D'media/'

💡 Hint

Common Mistakes

Adding extra slashes causing double slashes in URL

Using 'media/' string instead of MEDIA_URL setting

The function returns the full URL by joining MEDIA_URL and the filename without extra slashes because MEDIA_URL already ends with a slash.

Practice

1. What does MEDIA_URL represent in a Django project?

easy

A. The folder path where Django stores static files

B. The URL prefix used to access media files in the browser

C. The database table for storing media file info

D. The Python module for handling media uploads

Solution

1. Step 1: Understand MEDIA_URL purpose

   MEDIA_URL is used to define the URL prefix that browsers use to access media files uploaded by users.

2. Step 2: Differentiate from MEDIA_ROOT

   MEDIA_ROOT is the folder path on the server, not a URL. Static files and database tables are unrelated here.

3. Final Answer:

   The URL prefix used to access media files in the browser -> Option B

4. Quick Check:

   MEDIA_URL = URL prefix [OK]

Hint: MEDIA_URL is always a URL path, not a folder path [OK]

Common Mistakes:

• Confusing MEDIA_URL with MEDIA_ROOT
• Thinking MEDIA_URL is a folder path
• Mixing MEDIA_URL with static files settings

2. Which of the following is the correct way to set MEDIA_ROOT in Django's settings.py?

easy

A. MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

B. MEDIA_ROOT = 'static/media/'

C. MEDIA_ROOT = 'http://example.com/media/'

D. MEDIA_ROOT = '/media/'

Solution

1. Step 1: Understand MEDIA_ROOT type

   MEDIA_ROOT must be a filesystem path, not a URL or relative URL string.

2. Step 2: Check correct syntax

   Using os.path.join(BASE_DIR, 'media') correctly builds an absolute path inside the project folder.

3. Final Answer:

   MEDIA_ROOT = os.path.join(BASE_DIR, 'media') -> Option A

4. Quick Check:

   MEDIA_ROOT = absolute folder path [OK]

Hint: MEDIA_ROOT is a folder path, use os.path.join for safety [OK]

Common Mistakes:

• Setting MEDIA_ROOT as a URL string
• Using relative paths without BASE_DIR
• Confusing MEDIA_ROOT with MEDIA_URL

3. Given the settings:
MEDIA_URL = '/media/'
MEDIA_ROOT = '/var/www/myproject/media/'
What URL will serve the file stored at /var/www/myproject/media/photos/pic.jpg?

medium

A. http://example.com/media/photos/pic.jpg

B. http://example.com/photos/pic.jpg

C. http://example.com/static/photos/pic.jpg

D. http://example.com/media_root/photos/pic.jpg

Solution

1. Step 1: Match file path to MEDIA_ROOT

   The file is inside /var/www/myproject/media/, which matches MEDIA_ROOT.

2. Step 2: Combine MEDIA_URL with relative file path

   The URL to access the file is MEDIA_URL + 'photos/pic.jpg' = /media/photos/pic.jpg.

3. Final Answer:

   http://example.com/media/photos/pic.jpg -> Option A

4. Quick Check:

   MEDIA_URL + relative path = URL [OK]

Hint: URL = MEDIA_URL + file path relative to MEDIA_ROOT [OK]

Common Mistakes:

• Using MEDIA_ROOT as URL prefix
• Confusing static files URL with media URL
• Omitting MEDIA_URL prefix

4. You set MEDIA_URL = '/media/' and MEDIA_ROOT = 'media/' in settings.py. When you upload files, they are not accessible via browser. What is the likely problem?

medium

A. MEDIA_URL must end with a file extension

B. MEDIA_URL should be a filesystem path

C. MEDIA_ROOT and MEDIA_URL cannot have the same name

D. MEDIA_ROOT should be an absolute path, not relative

Solution

1. Step 1: Check MEDIA_ROOT path type

   MEDIA_ROOT must be an absolute path to the folder on disk, not a relative path.

2. Step 2: Understand impact on file serving

   Using a relative path can cause Django or the web server to fail to find the files, making them inaccessible.

3. Final Answer:

   MEDIA_ROOT should be an absolute path, not relative -> Option D

4. Quick Check:

   MEDIA_ROOT = absolute path [OK]

Hint: Always use absolute path for MEDIA_ROOT [OK]

Common Mistakes:

• Using relative paths for MEDIA_ROOT
• Expecting MEDIA_URL to be a folder path
• Not configuring web server to serve media files

5. You want to serve user-uploaded images stored in /home/user/project/media/ at URL prefix /uploads/. Which settings.py configuration is correct?

hard

A. MEDIA_ROOT = '/home/user/project/media/'
MEDIA_URL = '/media/'

B. MEDIA_ROOT = '/uploads/'
MEDIA_URL = '/home/user/project/media/'

C. MEDIA_ROOT = '/home/user/project/media/'
MEDIA_URL = '/uploads/'

D. MEDIA_ROOT = 'media/'
MEDIA_URL = '/uploads/'

Solution

1. Step 1: Match folder path to MEDIA_ROOT

   The folder /home/user/project/media/ is the physical location of files, so it must be set as MEDIA_ROOT.

2. Step 2: Set URL prefix to /uploads/

   To serve files at /uploads/, set MEDIA_URL = '/uploads/'.

3. Final Answer:

   MEDIA_ROOT = '/home/user/project/media/' and MEDIA_URL = '/uploads/' -> Option C

4. Quick Check:

   MEDIA_ROOT = folder path, MEDIA_URL = URL prefix [OK]

Hint: MEDIA_ROOT = folder, MEDIA_URL = URL prefix you want [OK]

Common Mistakes:

• Swapping MEDIA_ROOT and MEDIA_URL values
• Using relative path for MEDIA_ROOT
• Not matching URL prefix with desired access path
