            Reduce AbcSize metric when sanitizing params hash

            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.



            The following error is raised when I try to use twilio-ruby gem "warning: LoadError: cannot load such file -- rack/media_type"
            Asked 2022-Mar-06 at 23:50

            I am currently attempting to require "twilio-ruby" in a ruby file after adding it to my gemfile and doing $bundle install, however I keep getting the following error message when attempting to load the file in irb < warning: LoadError: cannot load such file -- rack/media_type >

            The error pathing leads back to .rvm/rubies/ruby-3.1.1/lib/ruby/3.1.0/irb/init.rb:397

            Answered 2022-Mar-06 at 23:50

            I think you've found a bug in twilio-ruby! Recently there was an update to the gem changing some behaviour in a rack middleware that is part of the gem. It lead to the gem requiring some behaviour from Rack, but in a situation where Rack isn't loaded, like your code above, this fails because Rack isn't a dependency.

            I've just made a PR to fix this. To fix this in the meantime, you can downgrade the version of twilio-ruby to 5.63.0, before the previous change was merged, or you can install rack as a dependency.

            The library is released every two weeks and the last release was February 24th. So if this fix is approved quickly, it could make it into this release.



            Returning a Hash as an 'else branch' dependant on Regex match
            Asked 2022-Mar-02 at 18:52

            The below is a challenge assignment so may not reflect 'real-world' code. I am trying to setup my method in a way that uses the properties of one hash to return a new hash. In this case, my method is taking an email as a string, uses regex to extrapolate the tld of the email and then outputs a hash-based message based of the tld. In this example, it generates an email in the language of the tld it registers.

            The code works as it should but is failing one test: "should return a Hash with the message informations in english for any other ccTlD mail"

            I cannot work out how to just set up a default value of 'en' when the tld is not in the original translation hash i.e. should just return the English-based translation.

            BONUS: I also note that my Rubocop doesn't like my styling because my compose_translated_email method has too many lines. I couldn't work out how to put the translation in another method without making that method too long too.

            Any help would be greatly appreciated - rather than just the answer, I would love if you could explain what the code is doing too. Thank you.



            Answered 2022-Mar-02 at 17:14

            Wouldn't it be enough to default the value of tld to en before creating the hash? As in:



            How to check for API compatibility between Ruby versions?
            Asked 2021-Dec-19 at 17:08

            Our team maintains a ruby script that must support any ruby >= 1.9.3 (yes, that's a pretty old ruby version but this is something outside our control at the moment). Recently, we added a change that included the verification of a regexp using match? and everything was going well until one of the users reported that the script was exploding for ruby 2.3 with the message:



            Answered 2021-Dec-18 at 00:13

            Do you have an automated test suite? If so, you can set up your CI to test against multiple Ruby versions, e.g.:


            (Edit: I see you did mention a test suite, so it sounds like you have a gap in the test coverage, or you're not running the tests against each Ruby version?).



            Rails: html_safe not safe?
            Asked 2021-Dec-04 at 15:36

            I have this working piece of code:



            Answered 2021-Dec-04 at 15:36

            Rubocop is flagging params[:text]&.html_safe as bad practice because this can expose your code to Cross site scripting attacks.

            Even brakeman raises issue for such cases. Check link

            In Rails 3, templates escaped output by default. Hooray! Sadly, Rails 3 also introduced the unfortunately named html_safe method to bypass this escaping. Quite a few people have been confused into thinking html_safe makes strings safe. What it really does is mark the string as “safe” so that it will not be escaped. (The raw method does the same thing.)

            html_safe api doc suggests to use sanitize instead

            The code after using sanitize method will look like -

            I have project and currently rubocop checks pass (I have rubocop_todo.yml). I'm trying to setup linter stage in Github Actions by myself (without third-party actions to run rubocop, that already exist) and for some reason rubocop does not pass there:

            Looks like it's reading the .rubocop.yml from one of your gems in the vendor/ directory. Try this:

            Bash filter out files with a given extension
            Asked 2021-Oct-12 at 22:42

            I've added a pre-commit hook to run Rubocop against any files that are being staged for commit. However, Rubocop errors out when you give it a .png or .svg file. I've added those file extensions to the exclude block in .rubocop.yml but because I'm actually explicitly supplying files by name that doesn't seem to do the trick.

            Here's my pre-commit script:



            Answered 2021-Oct-12 at 16:48

            One idea might be to filter out those extensions using grep.
