Is it possible to titleize in IRB?

I tried this :

User.find(1).update_attribute('first_name', '#{first.name.titleize}')

=> /#{first.name.titleize}

I am开发者_Go百科 not sure any other way to do this.

Many thanks

First, You need to use double quotes, ruby does not interpolate the embedded variable in single quotes.

Second, you need to bind the user to a variable in order to access the first_name attribute.

This should work:

u = User.find(1)
u.update_attribute(:first_name, u.first_name.titleize)
