ruby on rails - Model/ActiveRecord not saving new data -

-

i have confirmed method works. takes email controller , changes email of specific user.

however never saves data. pass wrong email format , returns false if pass correct email method returns true means assigned new email , called safe.

# allows user change email address def change_email(newmail)     address = emailveracity::address.new(newmail)    if address.valid?     self.email = newmail     self.save     return true   else     return false   end  end

i checked logs first hints nothing is: 

started post "/members/editmail" 127.0.0.1 @ 2013-04-25 17:33:44 +0200 processing memberscontroller#editmail html   parameters: {"authenticity_token"=>"*****=", "mail"=>"*****@gmail.com"}   ←[1m←[35muser load (1.0ms)←[0m  select `users`.* `users` `users`.`id` = 1 limit 1   ←[1m←[36mcharacter load (0.0ms)←[0m  ←[1mselect `characters`.* `characters` `characters`.`user_id` = 1←[0m   ←[1m←[35m (0.0ms)←[0m  begin   ←[1m←[36muser exists (0.0ms)←[0m  ←[1mselect 1 `users` (`users`.`email` = binary '*****@gmail.com' , `users`.`id` != 1) limit 1←[0m   ←[1m←[35muser exists (0.0ms)←[0m  select 1 `users` (`users`.`username` = binary '******' , `users`.`id` != 1) limit 1   ←[1m←[36m (0.0ms)←[0m  ←[1mrollback←[0m redirected http://localhost:3000/members/1 completed 302 found in 10ms (activerecord: 1.0ms)

also make sense have method change attribute. since i'm using devise gem authentication can use current_user variable retrieve user object logged in user , call current_user.email = newmail; current_user.save in controller.

self.save! throw exception when not saved.

also, might not right:

self.save return true

self.save returns true or false according if saved or not. might want rid of return true , let return value 1 returned self.save

selfkeyword not needed in context, neither return keywords. equivalent code:

# allows user change email address def change_email(newmail)     address = emailveracity::address.new(newmail)    if address.valid?     self.email = newmail     save     true   else     false   end end

that equivalent to

# allows user change email address def change_email(newmail)     address = emailveracity::address.new(newmail)    if address.valid?     self.email = newmail     save   end   address.valid? end

which should not want.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
