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

OK, here''s a quick summary on how to use will_paginate
install the gem:
gem install will_paginate
edit the the file config/environment.rb in your application''s
directory. add this line at the bottom:
require ''will_paginate''
now, in your controller:
def search
# I prefer setting my options hash separately, it makes it more readable
# take note of the :conditions key. the way you currently do it is
vulnerable to
# SQL injection because you stick the params directly in the SQL string.
# this method of using a Hash gets rid of the risk as Rails will escape
the params
options = { :order =>''author ASC'',
:conditions => [ "keywords like
:search_value", {
:search_value => "%#{params[:searchtextfield]} %" } ],
:page => params[:page]
}
@nejmvalues = NEJM.paginate(options)
end
to have a link to the pages in your view, you just put:
<%= will_paginate @nejmvalues %>
by default, will_paginate will display 50 entries per page if i remember
right.
to customize this, you can create a class variable in your model. so in
your
NEJM model, add these two lines at the start of the class declaration:
cattr_reader :per_page
@@per_page = 10 # will_paginate will display 10 results per page
hope this helps.

Hello all.. I''m new in Ruby on Rails. I''m doing an application which needs to use pagination. This is ok. I got to use it and I didn''t find any error. But I''ve got to put a city names "research" too. That''s the problem. The pagination failed. the variable doesn''t take its value. Below it''s my city''s list: Aracaju Editar Excluir Borborema Editar Excluir Brasília Editar Excluir Campinas Editar Excluir Campo Largo Editar Excluir Curitiba Editar Excluir Curralinho Editar Excluir Diadema Editar Excluir Florianópolis Editar Excluir Fortaleza Editar Excluir I want to look for all cities with letter "a". My code find them. But when I try to go to 2nd page, there is an error: You have a nil object when you didn''t expect it! You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.[] My variable doesn''t take the "research". Does anybody know what I can do about that?

I''m not sure what you mean, but if you need to include the "research" variable in your form (eg. for page 2) you can use a hidden field for that purpose.. lg // andreas -- DynamicDudes Lightweight Ruby on Rails application development http://dynamicdudes.com http://rubyphunk.com On Mon, Oct 20, 2008 at 3:14 PM, Tiago Pinto <rails-mailing-list-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote:> > Hello all.. > I''m new in Ruby on Rails.

Ok, thanks a lot.. I''ll try that. Just to know, my problem is like
described below:
__________________________________________________________________________________
How would I redirect a will_paginate link to a different, nested
resource?
For example, on the entries page I am paginating entries and it works
just fine. On the home page, I am also paginating entries, but only the
first 10 results. If you click next, I would like the user to be sent
to page 2 of the entries page.
The following does not work, as I am trying to go to
/journals/:id/entries?page=2
Code : - fold - unfold
1. :params => { :controller => "journal", :action =>
"index" }
It instead leads to /entries/index/3?page=2. Basically, I am trying to
send it:
Code : - fold - unfold
1. :url => journal_entries_path(@journal)
