Upgrade to ruby 3.0.5
Ruby 3.0 came with a few breaking changes which would cause much hassle for a typical rails app that uses a lot of gems, especially the keyword argument behavior breaking change and the removal of the URI.escape
method.
Keyword argument behavior change
- before ruby 3
irb(main):001:0> RUBY_VERSION
=> "2.7.6"
irb(main):002:1* def add(a: 1, b: 2)
irb(main):003:1* sum = a + b
irb(main):004:1* puts "#{a} + #{b} = #{sum}"
irb(main):005:0> end
=> :add
irb(main):006:0> add({a: 10, b: 20})
10 + 20 = 30
=> nil
- after ruby 3
irb(main):001:0> RUBY_VERSION
=> "3.0.5"
irb(main):002:1* def add(a: 1, b: 2)
irb(main):003:1* sum = a + b
irb(main):004:1* puts "#{a} + #{b} = #{sum}"
irb(main):005:0> end
=> :add
irb(main):006:0> add({a: 10, b: 20})

irb(main):007:0> add(**{a: 10, b: 20})
10 + 20 = 30
=> nil
No URI.escape
method and solution
