Question

I want to clear a table in my railsapp , without dropping the database and migrating…

 MyModel.all.each{|m| m.destroy} 

I would expect this code to delete every record in the my_model table, but this is not happening…
using Rails 2.3.4 + MySQL 5.1

EDIT:
the issue was based on the plugin better_nested_set which didn’t allow me to delete the entries in that order

MyModel.delete_all worked on the other hand , maybe because it executes truncate on the database (?)

Answer 1

Use MyModel.destroy_all to delete all the records for your model.
