sorry, i tried it but still didnt understand. maybe there is some step i missed ?

above is my DB table when i make modules based on related table that i made before.
when i post modules, its automatically create number on route column and on the first row (first post) is empty.
my question is,
- how to make the route on first column doesn't empty ?
- how to make the route column based on title ? so when i clicked the single page, the url will be like this ?
