I'm following Hartl's Ruby Tutorial. I'm on the beginning of chapter 5.
The instructions are to add an image ('rails.png') via
<%= link_to image_tag("rails.png", alt: "Rails logo"),
'http://rubyonrails.org/' %>
to the home page at: app/views/static_pages/home.html.erb
The image is downloaded via
$ curl -O http://rubyonrails.org/images/rails.png
$ mv rails.png app/assets/images/
However I am receiving an error on the asset precompile. I have no context on how to go about fixing this. So if there's extra info necessary to help solve this problem, let me know so I can add it!
This is the text of the error page of localhost:3000.
Sprockets::Rails::Helper::AssetNotPrecompiled in
StaticPagesController#home Asset was not declared to be precompiled
in production. Add Rails.application.config.assets.precompile += %w(
rails.png ) to config/initializers/assets.rb and restart your
server
Extracted source (around line #350): def
raise_unless_precompiled_asset(path)
raise Helper::AssetNotPrecompiled.new(path) unless precompiled?(path)
end
end
end

I've encountered similar issue a while ago and I've fixed it by adding .png files to precompiled assets. Just try updating your config/application.rb file with following line:
config.assets.precompile += %w(.png)
Please remember about re-starting your Rails server afterwards ;)

I'm creating a new rails application, and I'm working on the registration system, based on "rails tutorial" book, but I got a problem, when I run
rails test
on my local machine for my rails app, I got no errors
but when push the app to heroku, and then run
heroku run rails test
I got this error

I created my rails with this template that included webpack. But i still wrote my javascript code in app/assets/javascript. Now I am trying to deploy my app to heroku and it keeps failing. I get this error

remove bin/webpackor run bundle exec rake rails:update:bin
remove config/webpacker.yml
remove config/webpack
remove app/javascripts
remove config.webpacker.check_yarn_integrity = false from config/{development, test, production}.rb
verify that you don't have webpacker in your gemfile and run bundle install or bundle clean
imho, don't create your rails app with generators (unless it's your own)
I have searched over the web and stackoverflow but could not get this right.
I have a rails app and deployed to elastic beanstalk. The health is ok and green but the url is not working. It waits a little while and the page says connection time out.
when I type eb open
gives an error;
ERROR: OSError :: [Errno 10] No child processes
Could not figure out why this is happening.
When I eb deploy
INFO: Environment update is starting.
INFO: Deploying new version to instance(s).
INFO: Environment health has transitioned from Ok to Info. Application update in progress on 1 instance. 0 out of 1 instance completed (running for 4 seconds).
INFO: New application version was deployed to running EC2 instances.
INFO: Environment update completed successfully.
Can be a problem with load balancers? Where can I see if my database is created/migrated?

Changing config.force_ssl = true to false fixed it for me
my rails server seems like it is logging everything twice, not sure what is going on here, what should I do to investigate this ?

end
In my case this was caused by the rails_12factor gem. This gem adds the rails_stdout_logging gem which sends the logs to standard output. This can be useful in a production environment but not in development when Rails already does it by default.
https://github.com/heroku/rails_12factor#rails-4-logging
The solution is to only add this gem in production:
gem 'rails_12factor', group: :production
Have a look at this issue
Try adding the following code to you config/application.rb
if Rails.env.development?
# Don't log to STDOUT, by default rails s will handle it
config.logger = Logger.new('/dev/null')
else
# Don't log to file, sending everything to unicorn file.
config.logger = Logger.new(STDOUT)
end
Do you have your logger set to anything in either config/application.rb or config/environments/development.rb?
If nothing, try adding this line to config/environments/development.rb:
config.logger = Logger.new('/dev/null')
I had success with this in development.rb:
config.logger = ActiveSupport::Logger.new('/dev/null')
