You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: comment_result.go
    path of file: ./repos/mindoc/models
    
    the code of the file until where you have to start completion: package models

import "github.com/beego/beego/v2/client/orm"

type CommentResult struct {
	Comment
	Author       string `json:"author"`
	ReplyAccount string `json:"reply_account"`
}

func (m *CommentResult) FindForDocumentToPager(doc_id, page_index, page_size int) (comments []*CommentResult, totalCount int, err error) {

	o := orm.NewOrm()

	sql1 := `
SELECT
  comment.* ,
  parent.* ,
  mdmb.account AS author,
  p_member.account AS re
    
func (m *CommentResult) FindForDocumentToPager(doc_id, page_index, page_size int) (comments []*CommentResult, totalCount int, err error) {

	o := orm.NewOrm()

	sql1 := `

  LEFT JOIN md_comments AS parent ON comment.parent_id = parent.comment_id
  LEFT JOIN md_members AS p_member ON p_member.member_id = parent.member_id

WHERE comment.document_id = ? ORDER BY comment.comment_id DESC LIMIT 0,10`

	offset := (page_index - 1) * page_size

	_, err = o.Raw(sql1, doc_id, offset, page_size).QueryRows(&comments)

	v, err := o.QueryTable(m.TableNameWithPrefix()).Filter("document_id", doc_id).Count()

	if err == nil {
		totalCount = int(v)
	}

	return
