            Rails 7 ActionCable Unable to Connect
            Asked 2022-Mar-09 at 22:08

            I recently upgraded from Rails to With this upgrade I switched from webpacker to import maps with sprockets. My repo didn't include turbolinks or stimulus and I didn't feel like adding them now either. So I re-added UJS and most of my tests pass except the action cable feature tests. It seems I cannot get action cable to connect.

            Any help would be appreciated!




            Answered 2022-Mar-09 at 22:08

            Figured out the problem was because I had two applications.js files. One in app/assets/javascripts/ and another in app/javascript. Sprockets was serving my asset version of application.js due to my manifest pointing there. I adjusted the manifest and deleted the secondary application.js and all is working.



            Bundler could not find rake in any of the resources
            Asked 2021-May-23 at 12:27

            Im running ruby version 2.6.1 with docker. Rake gem is version 13.0.1.
            Whenever I tried docker-compose up, it always fails and throws this error everytime:
            This error did not exist before.



            Answered 2021-May-23 at 12:27

            I'm not really sure what happened and why but I tried doing this on my rails container and I was no longer receiving the said error.

            1. docker-compose run --rm bash
            2. cd to project directory
            3. bundle install



            How to fix brew doctor output with double question marks
            Asked 2021-Mar-12 at 01:53

            Running brew doctor the output is too long for the shell. Below is what I can still reach. Any idea what the warning (or error) for these might be and how to fix it?

            Some system info:

            Try doing brew update-reset. Do make a note of the following, however:



            Webpacker error related to module babel-plugin-syntax-dynamic-import
            Asked 2020-Dec-23 at 16:46

            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 )



            Answered 2020-Dec-23 at 16:46

            Webpacker changed from using .babelrc to babel.config.js between major versions 3 and 4. (Here is a link to the changelog where that is mentioned.) If this error pops up after the upgrade, it likely means that the legacy .babelrc file is still in the root of the Rails app. The solution is to delete .babelrc.



            Rubocop autocorrect for FrozenStringLiteralComment not working
            Asked 2020-Jul-19 at 19:26

            I have a Rails 6 project and am trying to use RuboCop's auto-correct option to fix the many Style/FrozenStringLiteralComment errors (mostly in generated files).

            No matter how many times I run bundle exec rubocop --auto-correct --only Style/FrozenStringLiteralComment from the project root, Rubocop will only report the errors, but not auto-correct them:

            app/models/product.rb:1:1: C: Style/FrozenStringLiteralComment: Missing frozen string literal comment.

            From running with the --show-cops option I can see that this cop 'Supports --auto-correct,' so am not sure what's wrong.

            My .rubocop.yml file has only one config setting: require: rubocop-rails.

            I've also run bundle exec rubocop -a and it has corrected other errors in config and similar files (single-quoting, mostly).

            Any idea why auto-correct won't work in this case? Thanks.



            Answered 2020-Jul-19 at 19:26

            This is a breaking change introduced in the version 0.87 (see the issue).

            Quoting from there:

            rubocop -a does all autocorrections, including unsafe ones. One has to add --safe-auto-correct to exclude unsafe ones.

            You should use the -A flag now to safe and/or unsafe autocorrect your files:

            rubocop -a / --autocorrect no longer run unsafe corrections; rubocop -A / --autocorrect-all run both safe and unsafe corrections. Options --safe-autocorrect is deprecated

            It should work for you as:
