$Model = M(); Just add a slash when instantiating and query can be used

query method does not exist, that means $crossingModel is not a model, try printing $crossingModel

Method one
Use query
$sql='';//Native sql statement
$res = M()->query($sql);
Method two:
1 $count=M('')- join()->where($where)->count();//Get the total number of records
//$page page number 10 displays data on each page
2 $pagearr=getPageArr($page,10,$count) ;
//The method used for paging is recommended to be placed in common
function getPageArr($page, $pagesize = 10, $count)
{

$page                    = isset($page) ? abs(intval($page)) : 1;
$pagesize                = isset($pagesize) ? abs(intval($pagesize)) : 10;
$page > 100000 && $page  = 100000;
$pagesize > 100 && $page = 100;
$pagetotal               = ceil($count / $pagesize);
($page > $pagetotal) && ($page = $pagetotal);
($page < 1) && ($page = 1);

//下一頁
if ($page > $pagetotal) {
    $nextpage = $pagetotal;
} else {
    $nextpage = $page + 1;
}
//上一頁
if ($page > 1) {
    $prevpage = $page - 1;
} else {
    $prevpage = $page;
}

$pagearr = array(
    "page"      => $page,
    "pagesize"  => $pagesize,
    "pagetotal" => $pagetotal,
    "count"     => $count,
    "start"     => ($page - 1) * $pagesize,
    "nextpage"  => $nextpage,
    "prevpage"  => $prevpage,

);
return $pagearr;

}
3 Then your limit can be written like this

->limit($pagearr['start'],$pagearr['pagesize'])
