I am using the below code to get the number of records.
self.size.to_s
How can i add '1' to the size from above?
self.size.next.to_s
(self.size + 1).to_s
#像这样
You can either add it before converting to string
(self.size + 1).to_s
Or if you already have a string
"2".to_i + 1
Combined this could be something like
self.size.to_s.to_i + 1
but that is hardly practical
