How do I pass multiple arguments to a ruby method as an array?
Ruby handles multiple arguments well.
Here is a pretty good example.
def table_for(collection, *args) p collection: collection, args: argsendtable_for("one")#=> {:collection=>"one", :args=>[]}table_for("one", "two")#=> {:collection=>"one", :args=>["two"]}table_for "one", "two", "three"#=> {:collection=>"one", :args=>["two", "three"]}table_for("one", "two", "three")#=> {:collection=>"one", :args=>["two", "three"]}table_for("one", ["two", "three"])#=> {:collection=>"one", :args=>[["two", "three"]]}(Output cut and pasted from irb)
Just call it this way:
table_for(@things, *args)The splat (*) operator will do the job, without having to modify the method.
class Hello $i=0 def read(*test) $tmp=test.length $tmp=$tmp-1 while($i<=$tmp) puts "welcome #{test[$i]}" $i=$i+1 end endendp Hello.new.read('johny','vasu','shukkoor')# => welcome johny# => welcome vasu# => welcome shukkoor
