Django - Caching

Given this template code:

{% cache 600 'menu' user.id %}

  Home
  Profile

{% endcache %}

What happens if user.id changes?

AA new cache entry is created for the new user.id

BThe cached fragment is reused regardless of user.id

CThe cache is cleared completely

DAn error occurs because user.id cannot be used

Step-by-Step Solution

Solution:

Step 1: Understand cache key with extra parameters
Extra parameters after the key string are used to create a unique cache key per value.
Step 2: Effect of changing user.id on cache
When user.id changes, Django creates a new cache entry for that user, so the fragment is cached separately.
Final Answer:
A new cache entry is created for the new user.id -> Option A
Quick Check:
Cache key + params = unique cache per user [OK]

Quick Trick: Extra params create unique cache keys [OK]
