ruby on rails - Have multiple edit forms. Need to modify update method and routes -

There is a user model with my name, email, password and bio.

I have to do this two kinds of edit type

a) If the update_attributes fails in updates

the method, Instead of just edit , presenting the correct page is my current update method.

  def update @ user.update_attributes (params [: user]) Flash [: success] = "profile updated" sign_in @user redirect_to @user else render 'edit' end '   
 b) How do I change  / users / 1 / edit  to change_password method? So I need something like  / users / 1 / change_password .  
 
 b)  matches' / users /: id / change_password ', for:' user # 
  redirect_to edit_user_path (@user)    
 
 
 code>  
 should work.  
 In addition, I will change my change_password paths in such a way:  
  Resources: Users subscribe 'change_password' end of the end   
 After which there is a more rail-way to do things, you can change  
  redirect_to - password_password_user_path (@user)
