I searched in Internet (http://wiki.github.com/mislav/will_paginate/
simple-search and http://railscasts.com/episodes/51), but I can't
solve my problem about pagination. The first page is ok, but when I
click the “Next page” or any other page link, I lose the FIELD1,
FIELD2, FIELD3 parameter(s). Can you help me? Thank you very much.
class Model < ActiveRecord::Base
...
def self.display(cond, par, page)
paginate :all,
:include => [:table1, :table2],
:conditions => [cond, par].flatten,
:page => page,
:per_page => 10
end
end
--------
class ModelController < ApplicationController
def start
...
end
...
def view
condition = "1=1"
param = []
(condition+=" AND models.FIELD1=?"; param << params
[:FIELD1].values) if params[:FIELD1]
(condition+=" AND models.FIELD2=?"; param << params
[:FIELD2].values) if params[:FIELD2]
(condition+=" AND models.FIELD3=?"; param << params
[:FIELD3].values) if params[:FIELD3]
@items = Model.display(condition, param, params[:page])
end
end
--------
view.html.erb
...
<%= will_paginate @items %>
--------
start.html.erb
...
<% form_tag(:action => "view", :method => "get") do %>
... # define FIELD1, FIELD2 and FIELD3
<% end %>
