ruby-on-rails - 如何传递参数[:search] with autocomplete_field_tag?

Question

我正在使用 Crowdint rails3 jquery autocomplete我的搜索表单有问题。

这是我的 search 表单在没有自动完成的情况下的样子:

<%= form_tag search_path, :method => 'get' do %>
    <%= text_field_tag :search, params[:search], :placeholder => "Search for a Product.....", :id => "main-search-field" %>
    <%= submit_tag "Search", :name => nil, :id => "main-search-field-button" %>
<%end%>

现在，当我更改自动完成和搜索的表单时:

<%= form_tag search_path, :method => 'get' do %>
   <%= autocomplete_field_tag 'name','', search_autocomplete_product_name_path, params[:search], :placeholder => "Search for a Product.....", :id => "main-search-field" %>
   <%= submit_tag "Search", :name => nil, :id => "main-search-field-button" %>
<%end%>

如果我的 autocomplete_field_tag 中有 params[:search]，这将不起作用:

ActionView::Template::Error (wrong number of arguments (5 for 4))

如何设置搜索参数以便我可以使用自动完成进行实际搜索？

class SearchController < ApplicationController
  autocomplete :product, :name, :full => true

  # Sunspot search.
  def index
    @search = Product.search do
      fulltext params[:search]
      paginate(:per_page => 1, :page => params[:page])
    end
    @products = @search.results
  end
end

# routes.rb
get 'search/autocomplete_product_name'
resources :search, :only => [:index]

(免责声明:我没有使用过这个特殊的 gem，以下答案仅基于对它的源代码的简要浏览。)

autocomplete_field_tag 方法根据来源接受五个参数，最后一个是选项散列:

autocomplete_field_tag(name, value, source, options = {})

因此，鉴于您的 Controller 方法，例如需要一个名为 product_name 的参数，您的方法调用可能应该是:

autocomplete_field_tag('product_name', '', search_autocomplete_product_name_path, :placeholder => "Search for a Product.....", :id => "main-search-field")
