Rails - Delete all Records that Meet a Condition

Question

How do you write in the Rails way? I have a model - Managers. I want to delete all records from Managers that meet the condition that manager_level is 5.

Thank you.

Answer 1

After Rails 5.1., We cannot pass conditions to delete_all/destroy_all method

Manager.where(:manager_level => 5).delete_all

This will run multiple queries to delete each record

But in Rails 6, we can use delete_by to delete using condition,

Manager.delete_by(manager_level: 5)

This will run single delete query

delete from managers where manager_level = 5
