Question

我通过另一次迁移从Student迁移中删除了两个字段middle_name，last_name后面临以下错误。以下是错误。

#p> StudentController中的Searchlogic :: NamedScopes :: OrConditions :: UnknownConditionError＃advanced_search

条件'last_name'不是有效条件，我们找不到与此匹配的任何范围。

请求

参数：

{ “搜索”=＆GT; { “顺序”=＆gt; “中”，   “first_name_or_middle_name_or_last_name_or_admission_no_like”=＆gt; “中姆兰”}，   “提交”=＆gt; “中搜索”}

以下是学生控制器中存在第816行的代码区域

def advanced_search
    @search = Student.search(params[:search])
    unless params[:search].present?
      @batches = Batch.all
    else
      if params[:search].present?
        @students = Array.new
        if params[:advv_search].present? and params[:advv_search][:course_id].present?
          unless params[:search][:batch_id_equals].present?
            params[:search][:batch_id_in] = Batch.find_all_by_course_id(params[:advv_search][:course_id]).collect{|b|b.id}
          end
        end
        if params[:search][:is_active_equals]=="true"
          @students = Student.ascend_by_first_name.search(params[:search]).paginate(:page => params[:page],:per_page => 30)
        elsif params[:search][:is_active_equals]=="false"
          @students = ArchivedStudent.ascend_by_first_name.search(params[:search]).paginate(:page => params[:page],:per_page => 30)
        else
          @students = [{:student => {:search_options => params[:search], :order => :first_name}},{:archived_student => {:search_options => params[:search], :order => :first_name}}].model_paginate(:page => params[:page],:per_page => 30)#.sort!{|m, n| m.first_name.capitalize <=> n.first_name.capitalize}
        end
        @searched_for = ''
        @searched_for += "<span>#{t('name')}/#{t('admission_no')}: " + params[:search][:first_name_or_admission_no_like].to_s + "</span>" if params[:search][:first_name_or_admission_no_like].present?
        @searched_for += "<span>#{t('name')}: " + params[:search][:first_name_like].to_s + "</span>" if params[:search][:first_name_like].present?
        @searched_for += " <span>#{t('admission_no')}: " + params[:search][:admission_no_equals].to_s + "</span>" if params[:search][:admission_no_equals].present?
        if params[:advv_search].present? and params[:advv_search][:course_id].present?
          course = Course.find(params[:advv_search][:course_id])
          batch = Batch.find(params[:search][:batch_id_equals]) unless (params[:search][:batch_id_equals]).blank?
          @searched_for += "<span>#{t('course_text')}: " + course.full_name + "</span>"
          @searched_for += "<span>#{t('batch')}: " + batch.full_name + "</span>" if batch.present?
        end

请帮助我不知道last_name存在于哪里，它显示错误，我对rails上的ruby非常新，需要这个。

提前致谢。

Answer 1

感谢回复，问题解决了。

问题在于索引迁移，实际上我从创建迁移中删除了列，但它已经存在于索引迁移中。

Answer 2

老兄，代码很庞大，不太可能有人通过一次阅读来理解它。安装rubocop或其他一些棉绒工具并清理那个烂摊子。
