Dynamic method calls

[Bill Reiflin]

I have a small program that dynamically calls methods such as column_name= from a hash. Pretty straight forward, except for the = part. I could store the = in the hash, but is ugly and might not always be in the method name.

This is what I have done, but it feels wrong:

h={:name=>'Alice', :age=>5}

t=Table.new

h.each {|k,v| t.send k.to_s+'=', v }

Comments?

That's pretty much it. I think I'd put that in Table's initializer though.

class Table
  attr_accessor :name, :age
  def initialize(options={})
    options.each do |k,v|
      k="#{k}="
      self.send(k,v) if self.respond_to? k
    end
  end
end

t=Table.new(:name=>'Alice', :age=>5)

p "#{t.name} and #{t.age}"
