python - flask optional url parameter not working -

- 

@mod.route('/participate/<survey_id>/', defaults = {'work_id':none}, methods = ['get','post']) @mod.route('/pariicipate/<survey_id>/<work_id>', methods = ['get', 'post']) def participate(survey_id, work_id):    /* do_something .. */

i can access http://localhost:5000/participate/512dc365fe8974149091be1f or http://localhost:5000/participate/512dc365fe8974149091be1f/ , if fire debugger can see work_id = none.

if try http://localhost:5000/participate/512dc365fe8974149091be1f/512dc365fe8974149091be1for http://localhost:5000/participate/512dc365fe8974149091be1f/512dc365fe8974149091be1f/ 404.

why happening? there i've done wrong routing rules?

your second route has typo in :)

@mod.route('/pariicipate/<survey_id>/<work_id>', methods = ['get', 'post'])

should be

@mod.route('/participate/<survey_id>/<work_id>', methods = ['get', 'post'])
