Ruby 3.1: implementing Dynamic Method Creation and Undefined Method Errors
I'm testing a new approach and I'm stuck on something that should probably be simple. I'm working with an scenario while trying to dynamically create methods in a Ruby class. Using `define_method`, I intend to generate a series of accessor methods based on a hash of attributes. However, when I call the dynamically created method, I'm getting an `undefined method` behavior. Here’s a simplified version of what I've implemented: ```ruby class DynamicAccessor def initialize(attributes) attributes.each do |attr| self.class.send(:define_method, attr) { instance_variable_get("@#{attr}") } self.class.send(:define_method, "#{attr}=") { |value| instance_variable_set("@#{attr}", value) } end end end accessor = DynamicAccessor.new(["name", "age"]) accessor.name = 'John' puts accessor.name # This works puts accessor.age # This raises `undefined method 'age'` behavior ``` The `name` method works as expected, but when I try to access `age`, it raises `NoMethodError: undefined method 'age' for #<DynamicAccessor:0x00007fffae0c3c30>`. I've verified that the `define_method` is being called with the correct symbols, and the `age` method should be defined, but it seems that the block isn't being executed as expected. I tried moving the method definitions outside the loop, but that led to similar issues. Is there a specific reason why this is happening? Is there a better way to implement this dynamic method creation in Ruby, especially in version 3.1? Any insights would be appreciated! Has anyone else encountered this? Thanks in advance! I recently upgraded to Ruby 3.10. Any help would be greatly appreciated!
