Truncate table(s) with rails console

Question

I have this testingdatabase which, by now, is stuffed with junk. Now I\'ve done a few Table.destroy_all commands in the rails console which deletes all records and dependencies

Answer 1

Model.connection.truncate(Model.table_name)

Answer 2

rake db:reset will perform rake db:drop db:setup. In other words, drop the database and setup the database again.

Answer 3

(A bit late to the party, I know)

Asking to do this in the console:

2.1.2 :001 > Post.all.each do |post|
2.1.2 :002 >   post.destroy!
2.1.2 :003 > end

Works as well...

This essentially loops through all of the posts and destroys them. It does not change your auto increment value though...

Same logic should work for Rails 3 as well (though I am using Rails 4)
