Ruby on Rails：在一次搜索中搜索两个模型

我有一个搜索页面，用户可以使用不同的下拉菜单搜索不同的项目。 他们可以一次搜索多个字段，如果找到与所有字段匹配的项目，搜索将返回一些内容。

inheritance我的项目控制器中的搜索操作：

def search @search = params[:client], params[:industry], params[:tech], params[:keywords] @project_search = Project.search(*@search).order(sort_column + ' ' + sort_direction).paginated_for_index(per_page, page) @search_performed = !@search.reject! { |c| c.blank? }.empty? @project = Project.new(params[:project]) @all_technols = Technol.all @project_technol = @project.projecttechnols.build respond_to do |format| format.html # search.html.erb format.json { render :json => @project } end end 

这是我的搜索视图。

   
  
 Client :  "-Any-", :selected => params[:client]) %>
 
 
 Industry :  "-Any-", :selected => params[:industry]) %>
 
 
 Technologies :  "-Any-", :selected => params[:tech]) %>
    true } ) %> 
  
 Keywords : 
 
 
 Results per page: params[:per_page]), { :onchange => "this.form.submit();"} %>
 <%#Results per page: params[:per_page]), :onchange => "'#{request.query_string}&per_page=' + this.getValue()" %>
 
 
 
  "button" %> 
  
  "button", :method => "get" %> 
 
  "button", :method => "get" %> 
 
 
  
 
  0 %>
