Code from sample app fails on AppEngine but runs in server mode #13

Closed jconti closed 11 years ago

jconti commented 11 years ago

I made a little site based on the sample app (http://john-conti.appspot.com). It works great running on a local server! However, when I deployed it, the post index and specific routes to a post do not work.

After looking at the logs and stack traces (one reproduced below), it looks like the app is unable to see the posts. I verified the hiccup files were in the deployed jar.

I suspect that AppEngine is not happy with the file operations on the included posts. Maybe it doesn't even set the directory correctly:

(def ^{:private true} current-path
  (. (java.io.File. ".") getCanonicalPath))

My questions are:

  1. Is logging the best way to debug this? If not, what else?
  2. If logging is my best shot, what is the way to log from Clojure using Gaeshi?

Thanks! John

John,

I've formally deprecated Gaeshi. https://github.com/slagyr/gaeshi/blob/master/README.md#deprecated All the sites I had on GAE using Gaeshi have been moved to AWS using Joodo.

I would think that logging is the best way to debug. But you never know with GAE… which is why I've abandoned it.

I'm sorry for any inconvenience this causes you.

Micah

Totally understood. Thanks for the software, I am enjoying it. Now off to AWS.

Thanks, John

PS: Is Heroku usable with Joodo?

slagyr commented 11 years ago

Yeah… Heroku's cedar stack can run Joodo apps. We've got a few Joodo apps running on Heroku for free. It's easier than AWS to get started.

Here's a gist that show how easy it is. Watch out for the old version.

Is there an option for lein 2?

bash-3.2$ lein plugin install joodo/lein-joodo "0.6.0-SNAPSHOT"
lein plugin install joodo/lein-joodo "0.6.0-SNAPSHOT"
The plugin task has been removed.

Please see the upgrade guide for instructions on how to use the user profile to
specify plugins instead: https://github.com/technomancy/leiningen/wiki/Upgrading
bash-3.2$

That gist is quite old. The current version of Joodo is 1.1.2

Is there an option for lein 2?

bash-3.2$ lein plugin install joodo/lein-joodo "0.6.0-SNAPSHOT" lein plugin install joodo/lein-joodo "0.6.0-SNAPSHOT" The plugin task has been removed.

Please see the upgrade guide for instructions on how to use the user profile to specify plugins instead: https://github.com/technomancy/leiningen/wiki/Upgrading bash-3.2$ — Reply to this email directly or view it on GitHub.
