What are some common errors I might encounter with Django QuerySets?
Some common errors include 'DoesNotExist', 'MultipleObjectsReturned', and issues with filtering.
Can you explain the 'DoesNotExist' error?
The 'DoesNotExist' error occurs when you try to retrieve an object that isn't in the database.
How can I handle the 'MultipleObjectsReturned' error?
You can handle it by ensuring your query returns a single object, or by using methods like 'get()' carefully.
What are some best practices to avoid these errors?
Use 'filter()' instead of 'get()' when expecting multiple results, and always check for existence before retrieval.
