What are some best practices for using Active Record in Rails?
Some best practices include using scopes for queries, avoiding N+1 queries, and keeping models thin.
Can you explain what N+1 queries are?
N+1 queries occur when an application makes one query to fetch records and then additional queries for each record to fetch associated data.
How can I avoid N+1 queries?
You can avoid N+1 queries by using the includes method to preload associations when querying.
What are scopes in Active Record?
Scopes are custom query methods defined in your model that allow you to encapsulate common queries and reuse them.
