hi all,          consider that I'm having 3 models 1)user 2)doc 3)udoc

user model=>(id,name) has_many:udocs has_many:docs ,through:udocs

doc Model=>(id,name) has_many:udocs has_many:users ,through:udocs

udoc Model=>(id,user_id,doc_id,start_date,end_date) belongs_to:user belongs_to;doc

Can anybody just tell how to access the extra field (start_date and end_date) in udocs table by using User Model

Assuming you have a user in, say, @user, then @user.udocs will give you an array of Udoc objects so you can do things like @user.udocs[0].start_date or @user.udocs.each do |udoc| # do something with udoc.end_date end
