An example of an AI chatbot conversation about querying databases in Ruby on Rails.
How do I query a database in Ruby on Rails?
In Ruby on Rails, you can use Active Record to query your database. For example, to find all users, you can use User.all.
What if I want to find a user by their email?
You can use the find_by method. For example: User.find_by(email: '[email protected]').
How can I filter users based on their created_at date?
You can use the where method. For example: User.where('created_at >= ?', 1.week.ago) to find users created in the last week.
Can I sort the results?
Yes! You can chain the order method. For example: User.order(created_at: :desc) will sort users by creation date in descending order.
