Is there a count_by_content alternative to the find_by_content action?
This is because I'm wanting to do the following in my pagination method:
def list
# step 1: set the variables you'll need
page = (params[:page] ||= 1).to_i
items_per_page = 20
offset = (page - 1) * items_per_page
# step 2: instead of performing a find, just get a count
item_count = Item.count_with_some_custom_method()
# step 3: create a Paginator, the second argument has to be the
number of ALL items on all pages
@item_pages = Paginator.new(self, item_count, items_per_page, page)
# step 4: only find the requested subset of @items
@items = Item.find_with_some_custom_method(items_per_page, offset)
end
