The Array extensions from will_paginate are for paginating a static array.
It returns a pagination object. Here are comments from the file:
# Example:
# arr = ['a', 'b', 'c', 'd', 'e']
# paged = arr.paginate(:per_page => 2) #-> ['a', 'b']
# paged.total_entries #-> 5
# arr.paginate(:page => 2, :per_page => 2) #-> ['c', 'd']
# arr.paginate(:page => 3, :per_page => 2) #-> ['e']
In my situation we are receiving an array which contains part of the total
response, as well as pagination info. Here is a JSON pseudo-response for
an API request for the first 25 "widgets":
{ "widgets": [widget1, widget2, etc...], "total_widgets":"125",
"total_pages":"5", "page":"1", "per_page":"25" }
Basically, I'm just looking for a library to handle the front-end task of
generating some links. I know it's not the most difficult task (a simple
view helper method could handle it), but I find myself having to repeat
this process often.
