ruby on rails newbie. i'm trying use pg_search gem running difficulties (yes, looking @ documentation). want search form has both text field , select field (category). here code have far:

contact_info.rb

class contactinfo < activerecord::base ... include pgsearch   pg_search_scope :search_by_category, (lambda |category, query|   raise argumenterror unless [:prev, :cat].include?(category)   {       :against => category,       :query => query   }   end end

home_controller.rb

class homecontroller < applicationcontroller   def index     @contact_infos = contactinfo.search_by_category(params[:query])     respond_to |format|       format.html # index.html.erb       format.json { render json: @contact_infos }     end end

home\index.html.erb

<%= form_for :search_by_category, :url => {:controller => 'home', :action => 'index'},   :html => {:method => 'get'} |f| %>    <%= text_field_tag :query %>   <%= f.label :category_id, "category" %>   <%= f.collection_select :category_id, category.all,                         :id, :name,                         {:prompt => 'all'} %>   <br/>   <%= f.submit "search" %> <% end %>

i'm getting error:

argumenterror in homecontroller#index wrong number of arguments (1 2)

...

request

parameters:

{"utf8"=>"✓","query"=>"test","search_by_category"=>{"category_id"=>"2"},"commit"=>"search"}

i understand problem in line:

@contact_infos = contactinfo.search_by_category(params[:query])

but i'm not sure how pass both variables view (home\index.html.erb).

thanks!
