How to use friend with compojure?

Question

I'm fairly new to clojure, and I'm trying to add an authentication system to a compujure app and for that I'm using cemerick.friend.

All the routes are working fine, but I'm never able to login, even when using a dummy in memory database (if you can call it that).

The problem, I believe, is on the cemerick.friend.credentials/bcrypt-credential-fn, which is never validating my credentials.

Here's a gist with the relevant code: https://gist.github.com/zamith/5940965

Any help on how to solve this problem would be nice.

Thanks.

You want to use workflows/interactive-form where currently you specify workflows/interactive-login-redirect.

The latter function's purpose is to serve as the default :login-failure-handler. What it does is perform the redirect after a failed login attempt; it certainly makes no attempt to log a user in.

You also need to remove the (resp/redirect "/signup") from the body of the friend/authenticated form in your "/dashboard" route, as it's unconditionally redirecting logged in users to the signup page. (That the redirect happens is in fact proof of the user being authenticated, since otherwise the body of friend/authenticated would not be evaluated and there's nothing else in the code which could cause a redirect to "/signup".)

With these two changes, the app works for me.
