dear all,
i am not able to use pagination plugin and i dont know much about ruby
on rails. the pagination code is as below:-
@searchvalue=params[:searchtextfield]
string1="Select count(*) from nejms where keywords like '%"
string2= @searchvalue
string3="%' order by author asc"
page = (params[:page] ||= 1).to_i
items_per_page = 20
offset = (page - 1) * items_per_page
@countvalue=string1.concat(string2)<<string3
@nejmvalue = NEJM.find_by_sql(@countvalue)
item_count = @nejmvalue.length
@item_pages = Paginator.new(self, item_count, items_per_page, page)
string4="Select count (select distinct
author,date,pubmed_article_id,efficacy from nejms where keywords like
'%"
string5= @searchvalue
string6="%' order by author asc)"
@queryvalue=string4.concat(string5)<<string6
@nejmvalue = NEJM.find_by_sql(@queryvalue,items_per_page, offset)
it gives me a error like this
NameError in SearchController#search
uninitialized constant SearchController::Paginator
