What will happen if you connect two different functions to the same Django signal using @receiver decorators?
AOnly the last connected function will be called
BThe signal will ignore all functions
CAn error will occur due to multiple receivers
DBoth functions will be called in the order they were connected
Step-by-Step Solution
Solution:

  1. Step 1: Understand signal multiple receivers behavior

    Django signals support multiple receivers; all connected functions run when the signal fires.

  2. Step 2: Confirm order of execution

    Functions are called in the order they were connected, no errors occur.

  3. Final Answer:

    Both functions will be called in the order they were connected -> Option D

  4. Quick Check:

    Multiple receivers all called sequentially [OK]
Quick Trick: Multiple receivers run in connection order [OK]
Common Mistakes:
MISTAKES
  • Thinking only one receiver runs
  • Expecting errors on multiple receivers
  • Assuming signal ignores duplicates
