Question

What is the most efficient way to delete an existing object from a Rails class? I have an array of objects

person_array = [Person1, Person2, Person3]

My goal is to delete all of the people in that array from a table in which they are members.

So I have a People class which they currently belong to.

I was thinking something like People.delete(person_array) which seems to be executing the proper SQL statements. How do I get those delete statements to actually change my People table though?

Answer 1

Since you already have the objects, you can just call destroy_all with them:

Person.destroy_all(:id => person_array)

Unlike delete_all, this will invoke the model’s callbacks, which may take longer, but preserves integrity.
