Deleting children

Rails
1

Hello again,

What is the best way to delete all children of a parent in a controller.
For example I have restaurants with a has_many association to
boundaries. I would like to do something like this:

@restaurant.boundaries.delete_all

is it possible?

Look at collection.clear under
