Will_paginate and record count

Rails
1

Hi,
I have just installed will_paginate plugin and got it working OK.

Excuse me if this is a very obvious question but how do you get access
to the total record count from all pages.

ie I want to display “nnn matching records”… followed by the <%=
will_paginate @records %>

With the old rails pagination I am using
count_collection_for_pagination which I always thought was a bit
tacky.

Cheers
Giorgio

Use the count method in AR, ex: User.countRails api docs is a good
reference.

Surely the will_paginate plugin must have its own count?
I could easily do a count on the database but that is an extra call
that presumably the will_paginate has already done?

Looking through the tests in will_paginate plugin, I think you can use
the
size method.
def test_simple_paginate
entries = Topic.paginate :page => nil
assert_equal 1, entries.current_page
assert_nil entries.previous_page
assert_nil entries.next_page
assert_equal 1, entries.page_count
assert_equal 4, entries.size

entries = Topic.paginate :page => 2
assert_equal 2, entries.current_page
assert_equal 1, entries.previous_page
assert_equal 1, entries.page_count
assert entries.empty?

# :page parameter in options is required!
assert_raise(ArgumentError){ Topic.paginate }
assert_raise(ArgumentError){ Topic.paginate({}) }

end

Enjoy!

Try using the total_entries method

@posts = Post.paginate_by_board_id @board.id, :page =>
params[:page], :order => ‘updated_at DESC’

total_records = @posts.total_entries
