Re: [Rails] Heroku and Javascript

Got some issues not sure how to fix.

My application.html.erb in Production on local system

Has the following code. Comes up with the error '(index):39 Uncaught ReferenceError: play is not defined at onload ((index):39)"

<!DOCTYPE html>

<html>

<head>

<%= render 'layouts/rails_default' %>

<%= render 'layouts/shim' %>

</head>

<%= render 'layouts/header' %>

<% flash.each do |message_type, message| %>

<%= content_tag(:div, message, class: "alert alert-#{message_type}") %>

<% end %>

<%= yield %>

<%= render 'layouts/footer' %>

<%= debug(params) if Rails.env.development? %>

</div>

</body>

</html>

Not sure how to fix that one?

In Heroku I get this error 'GET https://morning-caverns-39088.herokuapp.com/assets/blackJack.js 404 (Not Found)' which m,eans it can't find the assets/blackJack.js file

My BlackJack.html,erb file is as follows

<h2>Playing Black Jack</h2>

<div class ="blackJackdealer"><button class = 'button' >Dealer</button></div>

<div class = "blackJackplayer"><button class = 'button' >Player</button></div>

</div>

</div>

</div>

<div class ="blackJackplayButton"><button class = 'button' onclick="blackJackplayAgain()">Play Again</button></div>

<div id = "blackJackmoneyValue">Players Money is $5000</div>

<div id = "blackJackplayersReturn">Players Card Total is 0</div>

<div id = "blackJackmessagesValue">Messages</div>

</form>

</div>

</div>

function play()

{

blackJackshowCardInitialCards();

playGame = true;

return dealerCount,playerCount,playGame

}

</script>

My assets.rb file in config/initializers looks like this

# Be sure to restart your server when you modify this file.

# Version of your assets, change this if you want to expire all your assets.

Rails.application.config.assets.version = '1.0'

# Add additional assets to the asset load path.

# Rails.application.config.assets.paths << Emoji.images_path

# Add Yarn node_modules folder to the asset load path.

Rails.application.config.assets.paths << Rails.root.join('node_modules')

# Precompile additional assets.

# application.js, application.css, and all non-JS/CSS in the app/assets

# folder are already added.

# Rails.application.config.assets.precompile += %w( admin.js admin.css )

Rails.application.config.assets.precompile += %w( game.scss )

Rails.application.config.assets.precompile += %w( blackJack.js )

Rails.application.config.assets.precompile += %w( poker.js )

Rails.application.config.assets.precompile += %w( yaghtzee.js )

Rails.application.config.assets.precompile += %w( mastermind.js )

My _rails_default.html.erb file in views/layouts looks like this

<%= csrf_meta_tags %>

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

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

If you can find why the function play() can't be seen and why the javascript files in Heroku can't be find that would be great.

i put the links like <script type="text/javascript" src="assets/blackJack.js" ></script> for BlackJack.html,erb in BlackJack.html,erb because some function names were too similar causing issues.

Anything in browser javascript console? Is anything not being served properly? And, dumb question time but we all have these kind of moments, did you remember to precompile, and are all your JS libraries set to have pointers to the compiled locations of assets?

Cheers,

Subject: [Rails] Heroku and Javascript

I have built a games website in Rails. Runs run on local system. But when deployed to Heroku the Javascript requests either run slow or freeze. Often the whole page freezes. I'm only using one Dyno as I'm still in the testing phase.

Heroku doesn't have any suggestions to fix the problem

Slug size on Heroku is 36.5. MiB of 500 MiB
