cakephp中ctp文件的文件名长度限制

Is there any limit set on the length of ctp file name in cakephp? In my case i created a file with more than 40 characters name.But it is not rendered.I even used

$this->render('ajax_get_student_assignments_by_course_id');

But again it is not rendered .

No

There is no limit imposed by CakePHP.

$ cat views/pages/ajax_get_student_assignments_by_course_id.ctp 
MyFile's contents 
<?php die;
$ curl http://example.dev/pages/ajax_get_student_assignments_by_course_id
MyFile's contents
$

Which probably means there's an entirely different (fatal) error - which will probably show up in the error log.
