Deploy rails app to Heroku Error ArgumentError: Invalid option: harmony

I finished my blog and I'm trying to deploy it to heroku, but I keep getting this error.

I've tried changing my production.rb, Gemfile, and application.js which was advised from other people with the same problems, but none of it worked. Here's what I've done

I changed my production.rb to this

        config.assets.js_compressor = Uglifier.new(harmony: true)

Application.js:

        //= require jquery
        //= require jquery_ujs
        //= require turbolinks
        //= require ckeditor/init
        //= require_tree .

I've changed jquery_ujs to rails_ujs and it didn't change anything

Gemfile

ruby '2.5.1'

  gem 'pg'
  gem 'rails_12factor'
end

Override column_names for Model Class

I am customizing my Active admin with below code

ActiveAdmin.register Question do
  index do
    Question.column_names.each do |c|
      column c.to_sym
    end
  end
end

However, I don't want to show created_at and updated_at fields. How can I override this method for all of my Model Class to hide those two fields?

How to write ActiveJob log into a different file

I want to find a way to log ActiveJob logs to a different log other than the production.log

I am on a rails 4.2.5 project. The project used a lot of ActiveJob and DelayedJob. they write into same log, making the log very messy and hard to debug. I want to write the job log to a different file, so I did this in initializers/delayed_job.rb:

delayed_job_logger = Logger.new(File.join(Rails.root, 'log', "delayed_job_# {Rails.env}.log"), 10, 100 * 1024 * 1024)
Delayed::Worker.logger = delayed_job_logger
ActiveJob::Base.logger = delayed_job_logger

After the configuration, the delayed job logs is doing well. it did write to delayed_job_production.log

I, [2019-07-02T12:33:36.664242 #14335] INFO -- : 2019-07-02T12:33:36-0500: [Worker(delayed_job.6 host:pioneer3-app-production pid:14335)] Job ActiveJob::QueueAdapters::DelayedJobAdapter::JobWrapper (id=60672406) (queue=TfrToP2InTimeJob) COMPLETED after 0.0098

but the ActiveJob log is still mixing in the production.log

I, [2019-07-02T12:33:42.091068 #13730] INFO -- : [ActiveJob] [PipelineRollMonthJob] [93fc7600-2ba9-48eb-a6bd-729d3e830114] Performed PipelineRollMonthJob from DelayedJob(PipelineRollMonthJob) in 5.53ms

how can I fix the activejob log?

joins on tables without relation in rails

What's the work around of not being able to use joins on tables that don't have relation?

E.g:

class Student
end

class Lesson
end

There is no explicit correlation between Student and Lesson, however, in DB, we have implicit correlation: students.lesson_id and lessons.id.

Using pure SQL can join these two tables, however, using joins provided by rails like this:

Student.joins(:lesson).where('student.lesson_id=lesson.id')

will throw "Association named 'lesson' was not found on Student; perhaps you misspelled it?"

I'm looking for work around with below requirements:

• In order to improve the efficiency, using RDBMS queries will be ideal. (Rails sort_by, find etc are not)
• In order to improve readability, raw SQL is not ideal.

Is there any work around out there? Thanks!

How do I customize a view generated by a Comfy CMS Page?

In my Rails 3.2 app, I am using comfortable_mexican_sofa 1.8.

I have created some 'CMS Pages' within the CMS admin (some static pages like 'About Us', 'Contact Us', etc.). All of these pages are populated by the fields within the CMS Admin section.

But I can't figure out how to customize the template so that it renders the about us correctly.

Here is the log:

I don't have an 'about' path declared in my routes.rb, nor an about_controller and therefore I don't have a app/views/cms/pages/about.html.erb or anything like that.

I do have things like layouts/cms_inside which renders correctly, but it has a yield block that just renders the data collected from the text fields in the CMS Admin.

I have checked the documents at the GH repo, but it isn't clear about how to customize these generated pages.

Thoughts?
