Number of entries

Rails
1

I use will_paginate to get results:

@results = Users.paginate(:all, :conditions => "…

But how can I get a number of reults?

2

How can I write it simple?

if @results.empty?
x = 0
else
x = 1
end

3

x = @results.empty? ? 1 : 0

4

@results should never be nil unless he’s forgotten to define the
variable which would just be Bad Programming.

And instead of empty, you should use “blank?”, that would work even if
@results is “nil”

x = @results.blank? ? 1 : 0

to get a number of result you can get it by :

@results.size

if @results.size < 1
flash[:notice] = “There’s no result so its data is empty.”
end

@results.size will give you the number in that ‘page’
@results.total_entries will give you the total number of results you’re
paginating over
