I am iterating through a large array of model objects and need to paginate for performance/memory reasons.
I want to do something like this:
for i in 1..Person.num_pages
Person.page(i).each do
# work
end
end
Obviously I can get the count and do the math myself, but is there an equivalent of num_pages? Or is there a more elegant way of doing this altogether?
total_pages
.Yes, you can use total_pages
to retrieve the total number of pages in your model.
For example:
@blog_entries = Blog.all.page(1).per(20)
puts "total pages: #{@blog_entries.total_pages}"
Previous to version 0.14.0, the method was called num_pages
instead of total_pages
.
