Rails 5 - LoadError: Error loading the 'mysql2' Active Record adapter. mysql2 is not part of the bundle

Asked 2019-Nov-12 at 17:16

I have a long-term-stable Rails 5.1 app deployed to Ubuntu 18.04.3 using MySQL.

I came to deploy a mundane update yesterday, and for some reason I've started getting the error,

LoadError: Error loading the 'mysql2' Active Record adapter. Missing a gem it depends on? mysql2 is not part of the bundle. Add it to your Gemfile.

Of course, the gem is already in my Gemfile (and Gemfile.lock), and its installed on the deployment machine. I had made some unrelated Gemfile changes (switched to mini_racer and added bcrypt), which required me to update to Bundler 2.0.2 over 2.0.1, but that's it.

Things I've tried:

I've tried going back to the code base before any gem changes and switched back to bundler 2.0.1, but I still hit the same problem on deployment - now it's broken, it seems to be staying broken.
I tried deploying to a entirely independent server I have set up (still on Ubuntu 18.04) and now see the same problem.
I found these apparent duplicate questions, and there the fix was to go back to an earlier version of the mysql2 gem (I tried 0.3.20 as I saw mention that 0.3.21 doesn't work), but that doesn't fix it in my case. I've tried uninstalling all other versions on the server side.
The comments around the above linked question say this will be fixed in Rails 5 (I was already using 5.1) but I went through the exercise of updating my Rails app to 5.2 to get the very latest gems, and specified mysql 0.5.2 to see if I could leap frog the versions of mysql2 with the issue, but still I hit the same problem.

My 'current' Gemfile.lock file is pasted below, but this issue started with Rails 5.1.7 and Bundler 2.0.1 and I've tried all permutations of mysql2 0.3.18, 0.3.20 and 0.5.2.

Without a fix I am unable to deploy a Rails app update, so any suggestions as to how to overcome this deployment problem much appreciated.

Part of the problem here that mysql2 would not build on Ubuntu.

It turned out that upgrading to bundle 2.0.2, introduced a new config file in my Rails project,

Heroku build error: Specified 'sqlite3' for database adapter, but the gem is not loaded

What I'm trying to do

I'm building an app with rails and deploying a non master branch to heroku master test the app in production. I didn't want to mess with master until I know what I'm doing on Heroku, therefore I deployed a feature branch.

The repository of the app can be found here if the refernce is needed.

SQLite does not work with Heroku as its disk based and Heroku uses an ephemeral file system.

SQLite runs in memory, and backs up its data store in files on disk. While this strategy works well for development, Heroku’s Cedar stack has an ephemeral filesystem. You can write to it, and you can read from it, but the contents will be cleared periodically. If you were to use SQLite on Heroku, you would lose your entire database at least once every 24 hours.

Even if Heroku’s disks were persistent running SQLite would still not be a good fit. Since SQLite does not run as a service, each dyno would run a separate running copy. Each of these copies need their own disk backed store. This would mean that each dyno powering your app would have a different set of data since the disks are not synchronized.

-Heroku Devcenter: SQLite on Heroku

Heroku provides Postgres as the free default database for rails which is as close to a recommendation as you can get.

If you are deploying to Postgres you should also be developing/testing on Postgres.

Differences between backing services mean that tiny incompatibilities crop up, causing code that worked and passed tests in development or staging to fail in production. These types of errors create friction that disincentivizes continuous deployment. The cost of this friction and the subsequent dampening of continuous deployment is extremely high when considered in aggregate over the lifetime of an application.

If you really want to stick with SQLite you need to configure the adapters properly:

QUESTION

ActiveRecord read replica for reporting queries

Asked 2017-Feb-24 at 15:59

I have a Rails/ActiveRecord application that occasionally executes some heavy read-only queries against the application's models for ad-hoc admin/reporting purposes. I currently send these queries to a separate read-replica database endpoint using the seamless_database_pool gem so these queries do not add load to the primary database. However, this setup adds a constant runtime dependency on the replica, reducing my application's availability - whenever the replica goes offline for maintenance, the entire site returns 503 errors on any request, even though most requests never query the read-replica at all.

How can I connect to a read replica for ad-hoc reporting queries on ActiveRecord models without affecting the availability of my application? Is there another database-adapter gem that handles this use-case explicitly?

Or, (even better) is it possible to accomplish this directly using ActiveRecord? I know that it's possible to connect to a separate database by calling #establish_connection in order to direct a specific model to a separate database across all controller actions, but for my use case I need to connect to a separate database across all models, but only for specific controller actions.

...

ANSWER

Answered 2017-Feb-24 at 15:59

I managed to work around this issue by modifying the seamless_database_pool gem to relax the runtime dependency on the read-replica when only the master connection is being used. See the relevant issue and PR.
