我無法理解制作高級搜索表單的最佳方式。我在互聯網上進行了很好的搜索，在某些方面看，但我無法讓他們工作，因爲大多數建議都過時了。我已經提出了一個問題，但我認爲我太具體，我無法解決我的問題。我想在不同的文本框上搜索並用一個搜索按鈕下拉框。Ruby on Rails：高級搜索
EDIT2：
projects_controller：
def index
@projects = Project.all
respond_to do |format|
format.html # index.html.erb
format.json { render :json => @projects }
end
end
def search
@project_search = Project.search(params[:search]).order(sort_column + ' ' + sort_direction).paginate(:per_page => 2, :page => params[:page])
end

@project = Project.new
respond_to do |format|

%w[asc desc].include?(params[:direction]) ? params[:direction] : "asc"

搜索查看：

return scoped unless search_term.present?

路線：

root :to => 'projects#index'
end
正如你所看到的，我離完成應用程序還有點距離。我正在嘗試製作搜索表單，以便能夠在以下字段中進行搜索：項目名稱，客戶端，ID，行業，角色，技術，項目所有者，狀態，開始日期，結束日期和關鍵字。搜索表單將具有文本框或下拉菜單，具體取決於用戶正在搜索哪個字段。我想要鏈接每個領域並一次搜索所有領域。之前，我只是使用project_name和客戶端作爲示例，以使您更容易理解我的代碼。希望你現在可以看到我正在嘗試做什麼。
您看過這個[Railscast]嗎？（http://railscasts.com/episodes/111-advanced-search-form-revised ）？這可能會幫助你。 – 2012-07-23 08:39:22
