I ran bundle update rails and got this. I'm stumped. If activerecord-session_store 2.0 depends on a version of actionpack between 5.2.4.1 and above, and if actionpack is a dependency of Rails 6, shouldn't this be ok?

I'm aware of the recent mimemagic issues, which I managed to resolve on one of my Rails projects by bundle updating to 0.3.7 - but for some reason, I can't resolve it on the project below.
I have a Rails 6 project which I'm setting up for the first time on a new laptop. My laptop doesn't have the correct Ruby setup, so I've added a Dockerfile to my project like so:-

Answered 2021-Apr-28 at 13:29I can't compile your code. I can only spot a few random things, that might help you fix things:
Your threshold_indicator array is sixteen elements, but your loops go to index 24 This will lead to Undefined Behaviour (unless the loop incidentally
breaks before that point)valid_points_countis unused, yet it is being initialized to a magic numberYou can reduce a lot of code by not repeating yourself quite as much. E.g your code for the following bit took 45 lines of code. That's >4x as much.

/var/www/swan/code/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.7.3/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:23:in `require': cannot load such file -- listen (LoadError)
bundle install --deployment --without development test command install only production and general gems. Does not install the development or test gems. Rails read environment variables RAILS_ENV for the setting environment. RAILS_ENV variable if not set rails default accept development. And bundler try to load all gems + development group gems. But bundle install --deployment --without development test command only install production and general gems. So listen gem is not installed because listen gem in development group. RAILS_ENV=production bin/rails c command not throw error because not try to load development gems.

ANSWER
Answered 2021-Jan-08 at 00:14You have spring in your gemfile, usually hanging consoles and servers are related to that. The webrick gem was removed from the standard library in Ruby 3, so that's why it needs to be included in your Gemfile.
Re-add webrick to your Gemfile, do a bundle install, and then stop the background spring server with bin/spring stop. Then re-run the server.
Your best bet on solving issues with spring would be to head over and read about the gem on the GitHub project page, or opening a new question here on SO.

Answered 2021-Mar-28 at 15:53Default headers can be configured in config/application.rb. Trying moving your code out of ApplicationController and into config/application.rb. That's where you'll have access to the config object.
If you need to set custom headers within the context of a controller, you can use response.headers.

I have a blog that uploads banner and thumbnail images. I originally had it set to upload to the local directory using the carrierwave gem and I wanted to try to use digitalocean spaces since the app is deployed to the digitalocean app platform. I am able to get it working on localhost:3000 but when I deploy it to digitalocean it keeps reverting back to a previous deployment saying that a health check failed but not real errors.
I decided to deploy it to heroku since I am able to get actual errors. Here is the current error I get from heroku:
...ANSWER
Answered 2021-Mar-12 at 18:45It seems like the server can't access to the content of the credentials.yml. This file is encrypted and Rails use the master key store in the master.key file to read it. So given that the master.key is not checked into version control, you need to provide it manually on the server. Please check this article https://medium.com/cedarcode/rails-5-2-credentials-9b3324851336
This section :
Deploying master key
When you move your code to a server, you need to make sure that your config/credentials.yml.enc file can be decrypted. That means that somehow you’ll need to provide Rails with your master key, given that it is not checked into version control.
There are two ways of doing that:
Option 1: Place the config/master.key file in the server. You’ll normally want to symlink this file to a shared folder in the server filesystem. Again, do not version your config/master.key file.
Option 2: create a RAILS_MASTER_KEY ENV variable. Rails will detect it and use it as your master key, e.g. in heroku: heroku config:set RAILS_MASTER_KEY=.
You should be able to use any of those indistinctly.
If you are using RBENV as you ruby manager, you can store your env var doing this :
You will create .rbenv-vars in your project folder, not your rails project folder but the folder in which is your project folder, the parent folder if you want.
After that you put your env var inside the file like this:
DATABASE_PWD=*****
no quotes, no space too before ou after the "="
