Replacement for URI.escape that avoids Lint/UriEscapeUnescape warnings? - ruby-on-rails

Question

Not sure how to fix Rubocop's Lint/UriEscapeUnescape warning
Tried replacing URI with CGI thinking that was the "drop in" replacement but that blew up the test suite.
Here's the error followed by the line of code where URI is being used:
app/models/media_file.rb:76:5: W: Lint/UriEscapeUnescape: URI.escape method is obsolete and should not be used. Instead, use CGI.escape, URI.encode_www_form or URI.encode_www_form_component depending on your specific use case.
URI ...
^^^
# app/models/media_file.rb
...
def cdn_url(format: nil)
if format.nil?
"#{s3_config.cloudfront_endpoint}/#{escape_url(key)}"
elsif converted_urls.with_indifferent_access[format.to_s]
filename = converted_urls.with_indifferent_access[format.to_s]
if URI.parse(escape_url(filename)).host
filename
else
"#{s3_config.cloudfront_endpoint}/#{escape_url(filename)}"
end
else
converted(url)
end
end
...
private
def escape_url(url)
URI
.escape(url)
.gsub(/\(/, '%28')
.gsub(/\)/, '%29')
.gsub(/\[/, '%5B')
.gsub(/\]/, '%5D')
end
EDIT: Adding sample output of strings escaped with URI and CGI:
url: images/medium/test-image.jpg
URI.escape(url): images/medium/test-image.jpg
CGI.escape(url): images%2Fmedium%2Ftest-image.jpg
url: images/medium/test-image.jpg
URI.escape(url): images/medium/test-image.jpg
CGI.escape(url): images%2Fmedium%2Ftest-image.jpg
It would appear CGI is not a drop in replacement for URI as the listing error might have you believe. Thoughts?

Encounter with the same problem, got it fixed by using addressable lib.
escaped_query = URI.escape(search,
Regexp.new("[^#{URI::PATTERN::UNRESERVED}]"))
#W: Lint/UriEscapeUnescape: URI.escape method is obsolete and should not be used. Instead, use CGI.escape, URI.encode_www_form or URI.encode_www_form_component depending on your specific use case.
Solved by:
gem addressable gem in gemspec or Gemfile.
gem 'addressable', '~> 2.7'
require addressable/uri
Add appropriate.
escaped_query = Addressable::URI.encode_component(search, Addressable::URI::CharacterClasses::QUERY)
