Question

I am trying to create persistante variable local to my model but although something that sounds so simple is not working.

I have this in my model:

    class Coupon < ActiveRecord::Base

    @username = "empty"
    @admin = false


  def self.setUser(name, isAdmin)
    @username = name
    @admin = isAdmin        
  end

  def self.get_user (user)#an attempt to access the current_user but did not work i call this from the controller (I understand it is not best practice)
    #@user = user
    self.setUser(user.username,user.admin?)
  end 


  def has_not_occurred
    errors.add("property_of","name is not valid:#{@username}") if !validPropertyOf?

  end

  end
  def validProperty_of?
    return property_of == @username # || @Admin
  end



end

I actually get a “” instead of “empty” or the new value of username in set.user. How do I make these values persist? I have printed the values inside each method so they persist inside the method but not beyond for some reason.

@username is always nil or “” when it gets to has_not_accurred.
Why is this and how do I make it persist? Thank you so much.

I cannont access @user when I set it either (get_user method). I get a nil instance later down at validateProperty_of

Upgraded Rails now it works. Not sure why.
