I use rails-engine as a plugin of the application and I want to localize the validate message from the plugin: validates\_length\_of :login, :within =\> 3…40, :on =\> :create, :message =\> N\_("%{fn} is too short (min is %d characters)") It can not display the according language,where should i set it? I have tried to add require ‘gettext/rails’ GetText.bindtextdomain(“myd2d”) to init\_engine.rb or somewhere else,it can not work still. Thanks Charlie ---

Hi charlie, At first, did you fix your previous problem? [http://www.ruby-forum.com/topic/64942#new](http://www.ruby-forum.com/topic/64942#new) If not, fix the problem first. Because it may cause this problem. Then, a similer problem that “validates\_lenth\_of doesn’t translate anything” are reported by other person today. So I’ll investigate it ASAP. But if you have other informations about this. Report it more detail as you can, please. For example, validation in your model(not plugins) works, or every other messages are localized correctly, etc. On Tue May 09 14:36:51 JST 2006 ---

Hi, the previous problem you mentioned has been fixed,I use cookie to set local and it can work,however if i directly set local using the api that i used before,it can not work. I am still working this problem,and now I am clear that it is the reason of validates\_lenth\_of 's not working well,but other validates can work in PLUGINS,eg:validates\_uniqueness\_of,validates\_confirmation\_of,validates\_presence\_of sometimes validates\_lenth\_of can translate,but sometimes not,i am still summarizing the rules. unknown wrote: > Hi charlie, > > At first, did you fix your previous problem? > > [Gettext not worked in firefox,but done well under IE - Rails - Ruby-Forum](http://www.ruby-forum.com/topic/64942#new) > > If not, fix the problem first. > Because it may cause this problem. > > Then, > a similer problem that “validates\_lenth\_of doesn’t translate anything” > are reported by other person today.

I have tested the validates\_lenth\_of translation both in activemodels and plugins,and i think it has some bugs: validates\_length\_of :login, :minimum =\> 5, :on =\> :create, :message =\> N\_("%{fn} is too short (min is %d characters)") if the string above include “%d”,then validates\_length\_of string will not be translated by gettext,or else it can be done.

Thanks for reporting. I fixed them. Could you try it and report the result? 1. Get the newest rails.rb Revison 1.34 from: [http://rubyforge.org/cgi-bin/viewcvs.cgi/gettext/lib/gettext/rails.rb?root=gettext&view=log](http://rubyforge.org/cgi-bin/viewcvs.cgi/gettext/lib/gettext/rails.rb?root=gettext&view=log) 2. Replace this file to your rails.rb (e.g. /usr/lib/ruby/gems/1.8/gems/gettext-1.5.0/lib/gettext/rails.rb) 3. Try validates\_length\_of at models. 4. Then try validates\_length\_of at plugins.
