Retreiving column values from a variable column name

ruby-talk
1

text = shape.send(p)

essentially calls a method named 'p'. So:

'foo'.send('upcase') => 'FOO'

sd

···

however I am going to loop through a number of columns and the column
specified after the (.) will be a variable or string.

for p in particulars
  text = shape.p
end
