Express local library link problems

debelistic · July 4, 2018, 10:33am

Hi @chrisdavidmills , I’m learning express with the local library tutorial on mdn. Everything seems to be working fine except for my author detail page. The forward slash is not automatically inserted when I click the link from the author list page.

However, if I should insert the forward slash manually the link works perfectly. Pls your suggestions is highly and urgently needed. Below is a screenshot of the error page. Thank you

Hello!

This sounds like a fairly simple problem, maybe a typo in your router code? Maybe around this kind of area?

github.com

mdn/express-locallibrary-tutorial/blob/master/routes/catalog.js#L62


// POST request to delete Author
router.post('/author/:id/delete', author_controller.author_delete_post);


// GET request to update Author.
router.get('/author/:id/update', author_controller.author_update_get);


// POST request to update Author.
router.post('/author/:id/update', author_controller.author_update_post);


// GET request for one Author.
router.get('/author/:id', author_controller.author_detail);


// GET request for list of all Authors.
router.get('/authors', author_controller.author_list);




/// GENRE ROUTES ///


// GET request for creating a Genre. NOTE This must come before route that displays Genre (uses id).
router.get('/genre/create', genre_controller.genre_create_get);

If this doesn’t help, let me know which tutorial you got to when you first started to get a problem — what worked for you, and when did it stop working? The more information I have like this, the more easily I can try to pinpoint the problem.

I had this same exact problem. When I clicked on an author, I got this 404 page. Thanks to the OP I learned that my URL was missing the forward slash.

I traced the problem to the virtual for author’s URL in/models/author.js

Once I added the forward slash it worked as intended.

P.S. I also checked the tutorial, and it was fine. I must have missed the slash when typing it myself.
