在通过另一个迁移从学生迁移中删除两个字段中间名、姓氏后，我面临以下错误。以下是错误。

Searchlogic::NamedScopes::OrConditions::UnknownConditionError in StudentController#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。

要求

参数：

{"search"=>{"order"=>"", "first_name_or_middle_name_or_last_name_or_admission_no_like"=>"Imran"}, "commit"=>"Search"}

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，它的显示错误，我对 ruby​​ on rails 很陌生，重要的是需要这个。

提前致谢。

感谢回复，问题解决了。

问题出在索引迁移中，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。

伙计，代码很大，而且不太可能有人通过阅读一次就能理解它。安装 rubocop 或其他一些 lint 工具并清理混乱。
