Assets loading issue on Rails 5 app with Heroku

Question

I am facing asset loading issue in Rails 5 application deployed on Heroku.

App Configuration is,

ruby => ‘2.3.1’

rails => '~> 5.0.1'

When image is stored on path,

app/assets/home/image1.jpg

I am accessing it in view as,

= image_tag('/assets/home/image1.jpg’)

which is working properly in Development ENV, but not in Production ENV.

As per Heroku log,

ActionController::RoutingError (No route matches [GET] "/assets/home/image1.jpg")

If I am moving image directly to

app/assets/image1.jpg

then its working on Production ENV.

Please guide about it.

Thanks

It looks like you assets are not compile on heroku.

Follow below code:

config/environments/production.rb

config.assets.compile = true then run commands:

RAILS_ENV=production rake assets:precompile

then push all compiled files with menifest file to heroku.

Thanks. By setting config.assets.compile = true option, it works on heroku. And it works without pushing manifest file to heroku. Is it feasible to add 'public' directory to git commit code ? – Ehudd

@Mansi yes. Accept and vote my answer if it works for you. Thanks – Jaffna

What file does RAILS_ENV=production rake assets:precompile go into? – Twigg

@Twigg it creates some compressed files under public folder – Jaffna

better question -- @Jaffna is there a place that line of code can go in the production.rb so I don't have to run the command in terminal every time I change or add an asset? – Twigg
