Ruby delete_if block

Question

This is using Ruby 1.9.

I have a delete_if block:

@logHash[date].delete_if{ | logItem | logItem.name == name }

Where logItem.name is the name of the logItem and name is the name of the logItem I'm looking for. This works fine, except it deletes each logItem with the specified name. Is there a way to find the first item with an equal name and only delete that? So if there are two logItems that have the same name, I only want to delete one of them. Any ideas?

You're asking about an array, not a hash, right?

I'd use Array#index to find the index of the first item which had a matching name, and then Array#delete_at to delete it.

index_to_delete = @logHash[date].index {|log_item| log_item.name == name}
@logHash[date].delete_at(index_to_delete)
