Rails / Heroku Issues

Question

I am having troubles running my app on Heroku. The app works fine locally and gives me no errors when I push.

I am a bit of a noob but here are the logs.... what am I doing wrong exactly? A few things, I am sure ;)

Thanks!

Answer 1

Please replace the following code with line 5:

and run " heroku run rake assets:precompile " this command on project path

Answer 2

Errors

To give you some more information regarding running your app on Heroku, there are two types of error you will encounter:

Heroku

Rails

These errors will show when you try and load your Heroku app (http://***.herokuapp.com), and are relatively simple to decode.

• Rails errors occur because of your own code (typically you have a syntax error).
• Heroku errors occur because of how you've set up your Heroku environment (IE platform errors)

The difference is that if you have a Rails error, your application is running correctly on Heroku -- it just has a lot of internal issues, probably in regards to your syntax. If you see the Heroku error, it essentially means you don't have Heroku's platform setup correctly (typically no db), meaning you'll have to work on Heroku to sort it out.

---

Logs

The problem you're alluding to is a Rails issue, as you can see the details in the logs as to what the error might be. An important note is that Heroku errors will typically not report anything in your logs (but that's another story)

I would highly recommend using the LogEntries add-on:

Installing this, and then using the "real-time" functionality in the back-end will allow you to better digest the errors you're receiving. At least it helped us

--

Reading Logs is an art in itself. Typically, you'll be looking for specific "error" messages - but doing that can be quite difficult. The way I read your logs was as follows:

Upon browsing through your attachment, I found the following line:

ActionView::Template::Error (defaults.js isn't precompiled):

This should be the error (although it might be part of another). It explains that you don't have defaults.js in your app/assets/javascripts/ folder; which Jade McGough correctly pointed out, meant that you needed to reference the "application" JS file instead

Answer 3

Use <%= javascript_include_tag "application" %> on line 5 of your index.
