[web2py] Translation support in Auth Registration form

[mingcao ma]

Hi all,

I want to make my  Auth's registration table's label support translation.
So I add a fields in Auth

"auth.settings.register_labels"
Also  add this in register method in tools.py:

        form = SQLFORM(table_user,                                           
                           
                       fields = self.settings.register_fields,               
                           
                       hidden = dict(_next=next),                           
                            
                       showid=self.settings.showid,                         
                            
                       submit_button=self.messages.register_button,         
                            
                       delete_label=self.messages.delete_label,             
                            
                       formstyle=formstyle,                                 
                            
                       separator=self.settings.label_separator,             
                            
                       labels = self.settings.register_labels               
                            
                       )  

So that I can support registation form translation use code showing below:

auth.settings.register_labels = {'email' : 
T('Email'),'password':T('Password'), \                       
            'accept_promotion':T('Accept promotion Email?')}


May I ask is any better way I can achieve this?
Thanks for your help!
