Can you provide an script to reproduce this issue? it will be easier to pip-point the issue.
Probably this is not a CSV problem, specially if it's noted only when you upgrade Rails - so I'd suggest to review with and without Rails in your bundle.

You can use local csv by using gem "csv", path: "/local/path/to/csv" in your Gemfile:

$ git clone https:///github.com/ruby/csv.git /tmp/csv
$ editor Gemfile
(Replace 'gem "csv"' with 'gem "csv", path: "/tmp/csv".)
$ bundle instlal
$ ...

Hey @esparta

I used this code. I used this with my Rails 6 and it is working with all the same gems. This is not working only after I updated my rails and ruby version. Thanks.

Sorry if I was not clear, but with script I mean a complete example which the maintainers (and supporters as myself) can just execute and be able to reproduce without having your bundle. A line with the error it's not enough.

Here's something I did, and it's clear ruby 3.1.2 with bundled CSV gem has not the problem executing this minimal script:

require 'csv'
CSV.generate(headers: true) do |csv|
  csv << ['id', 'date', 'amount']
  csv << 123, '2022/05/09', 12.40]
end

from csv.

esparta commented on August 23, 2024

Thanks a lot @esparta Did you test this with rails 7.0.2?

No, I didn't and that's what I'm gently asking you: create a reproducible script:

Hey @esparta Thanks a lot for your suggestion. Honestly, I did not have any idea about these scripts. Here is my script,

        attributes = %i[id name version]

        all = [

            { id: 2, name: 'Rails', value: '7.0.2' },
            { id: 3, name: 'Bootstrap', value: '4' }
        ]

        CSV.generate(headers: true) do |csv|
            csv << attributes

            all.each do |data|
                csv << [
                data[:id],
                data[:name],
                data[:value]

Hey @esparta Thanks a lot for giving your time. I created a new app with specified ruby and rails version and it did work. I highly doubt if any of the gem I installed is causing this. I am still investigating this and dropping the gem file as well here in case any one wants to have a look.

Hey @kou Thanks a lot for suggesting this. I found the issue. .nil? was overwritten in my string.rb file for some reason which caused this. I removed it and now it is working. Thanks a lot all. closing this out.
