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

Have you tried using the will_paginate plugin instead?
GitHub - mislav/will_paginate: Pagination library for Rails and other Ruby applications
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.

You could do something like this in your controller:
@nejmvalues = NEJM.paginate :page => params[:page], :per_page =>
10, :conditions => [“keywords LIKE ?”, “%#{searchvalue}%”], :order =>
“author ASC”
And in your view:
<% paginated_section @nejmvalues do %>
… insert your results here …
<% end %>
Have you tried will_paginate? Ryan B. has a wonderful screencast
at
Also the will_paginate google group is helpfull. In the screencast
ryan bates shows how to put the pagination
in the model
Best wishes - Owen
How did you install the will_paginate plugin?
Dear Franz,
I tried to do the same as you told, but i am getting a error. It goes

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.

It looks like will_paginate is not loaded properly. Do you have the
“require” code in your config/environment.rb?
Rails::Initializer.run do |config|
…
end
require “will_paginate”
yeah i have made that change in the config/environment.rb file.

Hmmm that’s weird. Have you tried the plugin form of will_paginate?
script/plugin install git://github.com/mislav/will_paginate.git
