Hey Guys,

I deployed my app to Heroku but I am getting the "We're sorry, but something went wrong.
" so I ran heroku logs and this is what I got:

Got it, thanks Chris!

<%= form.date_select :year, :discard_day   => true, :discard_month => true, class: 'form-control' %>

Good day Rails Devs,

What's the proper way to dsiplay just the year in:

<%= form.date_select :year %>

Great job as alawys Chris, I'm creating an app with a Users model and Vehicles model, should I add the address to the Users model or the Vehicles model?

Hey Guys,

I'm following along with the How to Build a Forum with Jumpstart Pro video (https://www.youtube.com/watch?v=ZSom4V-nYxA&t=903s) and I am running into the error "The action 'create' could not be found for PostsController" when trying to reply to a discussion. Here are my files:

Great job guys I just purchased the pro version. Any idea on when the API feature will be available?

Thanks @eelcoj I give this a try!

Hey Rails Devs,

I'm developing an app and I want to send user random questions at random times on certain days. Are there any good Gems to do this or will I have to create something on my own?

Thanks in advance

I did and I got this:

yarn install v1.16.0
[1/4] 🔍  Resolving packages...
success Already up-to-date.
✨  Done in 0.45s.

I'm getting

error Command "webpack" not found.

The error is on the

<%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload' %>

Hey Chris ,

I'm getting this error:

Webpacker can't find application in /Users/robthomas/Dropbox/rails/sample/public/packs/manifest.json. Possible causes:

1. You want to set webpacker.yml value of compile to true for your environment unless you are using the webpack -w or the webpack-dev-server.
2. webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker's config/webpacker.yml file.
4. Your webpack configuration is not creating a manifest. Your manifest contains: { }

Extracted source (around line #10):

    <%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
    <%= stylesheet_pack_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
    <%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload' %>

Perfect, thanks Chris!!!

Cheers
