QUESTION
I'm trying to revive an old Rails application I worked on several years ago. I'm using ruby 2.3.3 and rails 3.2.15 on the Heroku-16 stack with ClearDB for my MySQL database with the mysql2 adapter. When deploying to Heroku it succeeds on the deploy but crashes when it tries to start the app.
Full stack trace from the Heroku log (updated after fixing activerecord-import gem version per suggestion in first answer):
...ANSWER
Answered 2021-Feb-09 at 01:07Looks like you're running into compatibility issues trying to use the latest version of the activerecord-import gem at the time of writing (released in October 2020) with activerecord 3.2.22.5 (released in September 2016). You do mention it's a rails 3.2.15 app but you're not using activerecord 3.2.15 which is confusing.
Try using activerecord-import 0.4.1 (released in July 2013) and activerecord 3.2.15 which should be compatible with rails 3.2.15.
QUESTION
I picked up a 4 year old project written in Ruby 2.1.3 and Rails 4.1.8.
Very few of the gems were versioned but I've managed to get the project running locally by installing mysql2 0.3.20 as suggested in multiple other threads. Doing this required me to (on MacOS) downgrade openssl and mysql with brew install mysql@57 and brew install openssl@10.
I could then install mysql2 with by passing the correct libraries to it:
gem install mysql2 -v 0.3.20 -- --with-mysql-config=/usr/local/opt/mysql@5.7/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl@1.0/lib --with-cppflags=-I/usr/local/opt/openssl@1.0/include
Everything works locally, all good.
I'm trying to deploy this project with Dokku on a Debian instance. Here's the readout from the push to dokku master including the error thrown when starting the Rails server:
...ANSWER
Answered 2020-Jun-22 at 18:38I think I see what's going on. In your Dockerfile, change your DB_URL from: mysql:// to mysql2://
You are loading the mysql2 gem, but indicating to ActiveRecord that you want to use a connection via the mysql gem.

Answered 2020-Mar-26 at 05:44This is probably and error with the stylesheet_link_tag and stylesheet_pack_tag, check out your layout files probably you are including sass files and you are using stylesheet_link_tag, this is breaking your code given that as I understand you can just link plane css files. so if you are including sass files use the stylesheet_pack_tag
QUESTION
I have a Rails (5.2.3) application to which I'm trying to add a chat feature so the users can communicate with each other. I have not fully implemented the feature, as I am trying to write tests as I go (if I don't know how to write tests for what I'm trying to test, I often do it this way). So far, I have two regions of the relevant page of the application laid out in HTML for the sending and reception of chat messages, JavaScript that runs the rest of the page, JavaScript that is intended to run on page load that makes the regions for the chat feature fill out the correct space of the page, JavaScript that listens to the textarea for chats to send, and JavaScript that listens for broadcast chats. The relevant test mimics what I can do at the moment in the development version: type text in the sending </code>, hit return, and see the message in the
that holds the chats. The development logs show that the message hits the redis server and are forwarded as expected.
The chat tool test fails. If I open the console in the browser running the tests, I see neither errors nor evidence that the JavaScript on the page is executed for this test (all of the other tests, all of which are tagged @javascript execute correctly). If I add enough of a delay, I can see that both of the methods I've employed to send the enter key to the textarea appear to work (in that the cursor moves), but the expected behavior on the page (that the text is sent to the redis server for broadcast) doesn't occur.
There's no evidence in the test log that the ActionCable server fires up. I have capybara-chromedriver-logger installed, but I see no evidence of the logging I would expect.
If there is information missing from my question that you think would be helpful in answering it, please ask.
The CoffeeScript I've written for the chat elements (which executes in development, but not in the test):
...ANSWER
Answered 2020-Feb-20 at 20:03Generally one would use the async actioncable adapter when testing (not the redis adapter) and you'd need to configure actioncable to run in app (in the test environment) - https://guides.rubyonrails.org/action_cable_overview.html#in-app - in order for it to start up when Capybara starts the application.
QUESTION
I cannot figure this out! Any help would be greatly appreciated.
Summary
After upgrading to Rails 5.2.3, my RSpec test fails but the app works fine in development.
The test failure states the asset, an image, is not in the pipeline. The problem is that the image is in the pipeline and the app displays the image correctly in development.
The app and RSpec tests work in previous versions of Rails (4.2 and 5.0)
Error
...ANSWER
Answered 2019-Sep-22 at 18:10I figured out the problem -- there was no image in the test environment pipeline.
In this app, each image is attached to a record in the database and only called when that record is displayed (think this can be be done using ActiveStorage in Rails5). The images are stored in the pipeline so everything worked in development and production. In testing, when the image was called there was no test image.
To fix this I adjusted the factory
QUESTION
I am migrating an application from Rails 4 to Rails 5 but am struggling to get a complete bundle due to dependency conflicts. I am a bit confused as to why this is a problem as I don't completely understand why the bundler cannot resolve the dependencies.
In this case, I am on Windows. I have installed Ruby 2.5.5 using BitNami Ruby and installed Rails 5.2.3. I deleted Gemfile.lock and ran bundle install. The Gemfile specifies Ruby 2.5.5 and Rails 5.2.3. No other gems have version requirements specified. Bundle is at 1.17.3.
My interest on this issue, other converting this particular application, is to better understand how bundle resolves dependencies. Looking at the bundler documentation, I haven't discovered the reason for some conflicts. As an example, why would the bundler not accept actionpack 5.2.3 in this case:
...ANSWER
Answered 2019-Sep-02 at 10:27I would suggest you to update your bundle by running "bundle update" than run bundle install
QUESTION
I postes this question because I didn't find any related answer on stackoverflow. I did everything. I will explain what I have tried.
When I start the Rails server using rails s, I get the following output:
ANSWER
Answered 2019-Jul-03 at 12:33The root of the problem seems to be bundler. What operating system and Ruby version are you using? It may be a problem with old OpenSSL library, so you can not install bundler and everything after it.
If you are using jRuby (your gem list output tells so), your problem seems to be the same as described in link. And there is a solution as well.
Maybe you forgot to set 2.1.2 version of ruby as global? (rbenv set global 2.1.2)
QUESTION
In my rails app when user creates a post, mail sent to the user who creates the post. I have tried "delayed_job_active_record" gem for background mailing operation. Mail sends successfully. After that, I am just trying to do same action using sidekiq via letter opener. Event happens and also letter opener shows the mail content. After that, instead of letter opener use google smtp settings. Even, sidekiq opens the letter opener without sending emails. So, I uninstall the letter opener. But that causes an error like this
No such file or directory letter opener
This is my Posts_controller:::

Answered 2019-May-15 at 13:17Try to restart the server!! If nothing happens means try to restart the system.

Install launchy
On a UNIX-like operating system, using your system’s package manager is easiest. However, the packaged Ruby version may not be the newest one. There is also an installer for Windows. Managers help you to switch between multiple Ruby versions on your system. Installers can be used to install a specific or multiple Ruby versions. Please refer ruby-lang.org for more information.
