ruby on rails - Updating password with BCrypt -

-

when login username , password bcrypt checks no problem, fine.

but when go through process of recovering password , try login new password bcrypt never returns true.

the code have follows:

before_save :encrypt_password before_update :encrypt_password  def authenticate    player = player.find_by(mail: self.mail)    unless player.nil?    current_password = bcrypt::password.new(player.password)    if current_password == self.password     player    else      nil    end  end end  private def encrypt_password     unless self.password.nil?     self.password = bcrypt::password.create(self.password) end

i'm using rails 4

you don't need before_update callback.

when creating new record (user in case), before_save triggered. right behavior.

but when updating record, both before_update , before_save triggered, means password column encrypted twice. that's why unexpected behavior.

check this page more information callbacks.

what's more, think it's bad idea make password real column in database. need column called encrypted_password in database , making password virtual attribute.

so can write encrypt_password method this:

def encrypt_password     unless self.password.nil?     self.encrypt_password = bcrypt::password.create(self.password) end

which gave no chance make mistake made.

when save object, got below error must non-abstract type public parameterless constructor in order use parameter 't' in generic type or method 'servicestack.redis.redisclient.store<t>(t) redisclass.getinstnace().store(msg); // error here redisclass.getinstnace().save(); as third party's class, can not edit how save object? could create wrapper around third party object call constructor, store wrapper? e.g. public class mywrapper { public thirdpartyobject thirdpartyinstance { get; set; } public mywrapper() { thirdpartyinstance = new thirdpartyobject("constructors"); } }

time series - R growth rate calculation week over week on daily timeseries data -

-
i'm trying calculate w/w growth rates entirely in r. use excel, or preprocess ruby, that's not point. data.frame example date gpv type 1 2013-04-01 12900 office 2 2013-04-02 16232 office 3 2013-04-03 10035 office i want factored 'type' , need wrap date type column weeks. , calculate week on week growth. i think need ddply group week - custom function determines if date in given week or not? then, after that, use diff , find growth b/w weeks divided previous week. then i'll plot week/week growths, or use data.frame export it. this closed had same useful ideas. update: answer ggplot: all same below, use instead of plot ggplot(data.frame(week=seq(length(gr)), gr), aes(x=week,y=gr*100)) + geom_point() + geom_smooth(method='loess') + coord_cartesian(xlim = c(.95, 10.05)) + scale_x_discrete() + ggtitle('week on week growth rate, apr 1') + ylab('growth rate %') (old, correct answer using plot) w...
