How to assign currently logged in user name to a table field

I have 3 tables items (columns are: id, name , type) history(columns are: id, date, username, item_id, user_id) user(id , username, password)

When a user "ABC" logs in and creates a new item, a history record gets created with the following after_create filter. How to set the username field in history table to "ABC".

class Item < ActiveRecord::Base has_many :histories after_create :update_history def update_history histories.create(:date=>Time.now, username=> ?) end

My login method in user_controller def login       if request.post?       user=User.authenticate(params[:username])       if user         session[:user_id] =user.id         redirect_to( :action=>'home')            flash[:message] = "Successfully logged in "       else         flash[:notice] = "Incorrect user/password combination"         redirect_to(:action=>"login")       end     end   end

I am not using any authentication plugin. I would appreciate if someone could tell me how to achieve this without using plugin(like userstamp etc.) if possible.

Hi, If u dont want to use any of the plugin then u need to write ur own action and need to do manually.

Like:

def current_user    @current_user = User.find(session[:user_id]) end

Keep this action into ur application controller, It will return u the current logedin user object. So u may use this like

def update_history histories.create(:date=>Time.now, username=> current_user.name) end

I hope it will work 4 u. But instead of doing manually I suggest u must use Authlogic gem/plugin it will gives u other benefits also.
