Interpolation

Hi -

I am adding a series of records within a for loop using i as my counter. Rather than hard code the model attributes I would like to dynamically create them.

Here's what I'm trying to do:

I have several fields on my example model named such as: spec_1_english spec_2_english etc...

This is what I would like to do - create these attributes dynamically using my counter.

for i in (0..2)     example.spec_#{i}_english = "test value"     l.save end

Any help appreciated.

Thanks!

You could use #send. Try something like this:

(0…2).each do |i| example.send(“spec_#{i}_english=”, “test value”) l.save end

Do you really want l.save instead of example.save, though? Maybe there’s some context missing from your code snippet.

Regards, Craig

Excellent - this worked great. Another tool for me to use. You're correct l. was an error on my part in my snippet.

Thanks Craig
