(Apologies if this question is simple...I've been at this for a few days now)

So...I've recently changed my model, controller and partial _form.html.erb files to implement a Nested form...

And now my jbuilder file needs to be refactored but I'm a noob on pulling out nested values...

original index.json.jbuilder

I am re-writing a program called Emissions Gateway to the new version of Ruby on Rails.

I have a method that was written with syntax from a gem called Squeel and I am having a very hard time re-writing it. I have been failing at it for over 4 hours and can't seem to get it figured out.

This is the method right here, it is in a model called datalogger.rb along with the schema information for the datalogger.rb model.

I am more of a Java programmer and still somewhat new to development (2 years or so, can write Java code & web apps just fine) however the company I work for has 4 Rails applications and was asked to get this application working called CtrlPanel. I have been having to learn Ruby on Rails in order to help get this issue with this app fixed and get it working.

I have been working on this problem for over a week all day long every day and nothing I do is fixing it.

I fixed everything to the point the app comes up, web server runs serves the pages but all views are white screens as long as this application.html.haml file is present. I re-wrote the file with very basic bootstrap and it sort of works but nothing looks right. The problem seems to stem from 1 single like that simply says: = javascript_include_tag "application"

I have been all over the internet and have tried every single fix from changing coffee-script-source to v1.8.0 as I read Windows has an issue with newer rails and that file, I have tried every variation of changing it from application to default, and every type of ending you can think of no matter what I do it gives me this error message which I can not seem to find.

I am not even sure WHAT that line does, I assume it has to do with the new Google Maps API and I verified the key is valid and it was working before.

This is the error is it giving it says the line with "= javascript_include_tag" "application" giving error ExecJS::RuntimeError at / SyntaxError: [stdin]:1:1: unexpected //=

I am running a PC on Windows 10 20H2 x64 UEFI ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x64-mingw32] Rails 6.1.3

(I did also install Ubuntu on another machine and it gives the exact same error, also gives the same error on another Windows machine)

The app is working IF I delete the "application.html.haml" file and put in a skeleton basic version all of the other views start working but of course none of them look right no menus no bootstrap no nothing.
Here is the application.html.haml file.

My app works locally, however when I try to deploy to Heroku, I get a Sprockets::FileNotFound: couldn't find file 'angular' with type 'application/javascript' error.

I have tried precompiling with RAILS_ENV=production bundle exec rake assets:precompile and purging my build cache with heroku builds:cache:purge -a findum, but still no luck. I recently migrated from Bower to Yarn– not sure if my asset path is the problem?

Has anyone run into a similar error that they were able to resolve? So many thanks 🙏.

This is my application.js :

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):

I'm trying to build a simple app that is just using a GitHub login for authentication for now. I am using Rails v5.2.3 for the backend, and React for the frontend. I currently have a button in my Root Component that sends an ajax request to my backend. That request will hit an action in my SessionsController that will redirect to the /auth/github route and begin the GitHub auth cycle.

I believe this is step is where I am getting an error.

My browser console gives me this error message:

Getting an error trying to load a page. Rails 6, Ruby 2.7.1. Webpacker for javascript and SCSS From the Terminal (similar to the Chrome Console error )

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:

I'm trying to push some modifications of my Ruby on Rails web to Heroku but it says "push rejected". The error comes after "Detecting rake tasks" and here's the message:
