検索が完了するまで検索結果を非表示にしようとしています。ホームページから検索ページをクリックすると、ページに検索ボックスが表示されますが、すべてのデータベースがテーブルに表示されます。検索オプションと検索ボタンを表示したいだけで、検索に応じて正しいテーブルが表示されます。

これが私の検索ビューです：

<h1>Search</h1>

<%= form_tag search_path, method: :get do %>

Client :
<%= select(@projects, :client, Project.all.map {|p| [p.client]}.uniq, :prompt => "-Any-", :selected => params[:client]) %></br>

<%= text_field_tag :keywords, params[:keywords] %></br>

<%= submit_tag "Search", name: nil %>

<% end %>


<% if @search %>

</table>

Results per page: <%= select_tag :per_page, options_for_select([10,20,50], params[:per_page].to_i), :onchange => "if(this.value){window.location='?per_page='+this.value;}" %>

<%= button_to "Search Again?", search_path, :method => "get" %>

<%# end %>
<%= button_to "Home", projects_path, :method => "get" %>

検索アクションは次のとおりです。

def search


@search = params[:client], params[:industry], params[:role], params[:tech], params[:business_div], params[:project_owner], params[:exception_pm], params[:status], params[:start_date], params[:end_date], params[:keywords]

@project_search = Project.search(@search)

   @project = Project.new(params[:project])

respond_to do |format|
      format.html # search.html.erb
      format.json { render :json => @project }
    end

end

これが私のモデルです。

class Project < ActiveRecord::Base
  attr_accessible :business_div, :client, :customer_benifits, :edited_date, :end_date, :entry_date, :exception_pm, :financials, :industry, :keywords, :lessons_learned, :project_name, :project_owner, :role, :start_date, :status, :summary, :tech

validates_presence_of :business_div, :client, :customer_benifits, :end_date, :exception_pm, :financials, :industry, :keywords, :lessons_learned, :project_name, :project_owner, :role, :start_date, :status, :summary, :tech





def self.search(search_client, search_industry, search_role, search_tech, search_business_div, search_project_owner, search_exception_pm, search_status, search_start_date, search_end_date, search_keywords) 
  return scoped unless search_client.present? || search_industry.present? || search_role.present? || search_tech.present? || search_business_div.present? || search_project_owner.present? || search_exception_pm.present? || search_status.present? || search_start_date.present? || search_end_date.present? || search_keywords.present?

if search_start_date != ""
search_start_date = Date.parse(search_start_date).strftime("%Y-%m-%d")
end
if search_end_date != ""
search_end_date = Date.parse(search_end_date).strftime("%Y-%m-%d")
end



  where(['client LIKE ? AND industry LIKE ? AND role LIKE ? AND tech LIKE ? AND business_div LIKE ? AND project_owner LIKE ? AND exception_pm LIKE ? AND status LIKE ? AND start_date LIKE ? AND end_date LIKE ? AND keywords LIKE ?', "%#{search_client}%", "%#{search_industry}%" , "%#{search_role}%" , "%#{search_tech}%" , "%#{search_business_div}%" , "%#{search_project_owner}%" , "%#{search_exception_pm}%" , "%#{search_status}%", "%#{search_start_date}%", "%#{search_end_date}%","%#{search_keywords}%"])



end


def self.paginated_for_index(projects_per_page, current_page)
    paginate(:per_page => projects_per_page, :page => current_page)
  end

end

うまくいけば、私が何をしようとしたかがわかります。wrong number of arguments (1 for 11)パラメータを分割していないため、エラーが発生しています。しかし、私が使用する*@searchと、大量のエラーが発生します。

テーブルを非表示にしようとする前に、コントローラーの元のコードは次のようになりました。

@project_search = Project.search(params[:client], params[:industry], params[:role], params[:tech], params[:business_div], params[:project_owner], params[:exception_pm], params[:status], params[:start_date], params[:end_date], params[:keywords]).order(sort_column + ' ' + sort_direction).paginated_for_index(per_page, page)

引数の配列を展開して引数を分離するようRubyに指示するには、引数を@search渡すときにparamsをスプラットする必要があります。.searchProject.search

@project_search = Project.search(*@search)

スプラットの使用に関する情報

編集 (フォローアップの質問に回答するため)

でのテスト

<% if @search %>

またはtrueだけであっても、常に に評価される値を持つため、十分ではありません。これを適切に確認する 1 つの方法は、検索フィルターですべてのフィールドが空白の場合に新しいブール インスタンス変数を作成することです。[]["", "", "", "", "", "", "", "", "", "", ""]true

# put this after you set @search in your action
@search_performed = !@search.reject! { |c| c.blank? }.empty?

@search_performedそして今あなたのビューでテストしてください

<% if @search_performed %>

配列を格納しているので、演算子@searchを使用する必要があります*

@project_search = Project.search(*@search)
