🔍 Read Records with find, find_by, and all​

Active Record offers various methods to fetch data: find raises an error if not found, find_by returns nil, and all returns every record. Use the one that matches your error-handling needs.

# Raises ActiveRecord::RecordNotFound if ID 1 doesn't exist
user = User.find(1)

# Returns nil if no record matches
user = User.find_by(email: 'noone@example.com')

# Fetches all records (returns an ActiveRecord::Relation)
users = User.all
