Hi all

I have a model called,article which belongs\_to user  
so in article.rb  
belongs\_to :user

and in user.rb  
has\_many :posts, :dependent =\> :nullify, :class\_name =\> ‘Article’

so now @user.posts is giving the posts of the user

Now like,without using any named\_scope,  
i would want @user.posts to give out only the posts which were published  
before 10 days.

I know i can use a named\_Scope  
But i want to directly use @user.posts alone to get the above result.

Is it possible to do this??

Thanks In Advance,

Charanya

That’ll return all posts that were created in the 10 days before the  
application was started (because 10.days.ago is evaluated in the class  
body). To return all posts that were created in the 10 days before the  
query is run, you want:

has\_many :posts, :conditions =\> proc { [‘created\_at \>= ?’, 10.days.ago]  
}
