Hi
I have an active record object collection. I want to change the value of
the key called “mail”.
@users.collect {|s|s.attributes.x_method { if key == mail then replace @
something else (ex: value.gsub(/@/," (at) ") }}.to_json
How can I achieve my gold?
thanks

I’d probably just write something simple like:
h = s.attributes
h[‘mail’].gsub!(’@’,’ (at) ') if h[‘mail’]
If you really want to iterate, then
h = s.attributes
h.each { |k,v| h[k] = v.gsub(’@’,’ (at) ') if k==‘mail’ && v }
And if you want to write it as a one-liner, look at inject or merge. If
you know there’s always a mail attribute, then:
s.attributes.merge( ‘mail’ => s.attributes[‘mail’].gsub(’@’,’ (at) ’
).to_json
