Conditional named_scope chaining with params (Need help)
Hello there,
I have a model that has more then one named_scope.
In my action Index of the controller that handle this model I want to do
this in a drier way:
if params[:ownership] == "mine"
@posts = Post.tagged_with(params[:tags], :on =>
:tags).owner(current_user.id).paginate :all, :page => params[:page],
:order => ''created_at DESC''
else
@posts = Post.tagged_with(params[:tags], :on => :tags).paginate
:all, :page => params[:page], :order => ''created_at
DESC''
end
This is just a example, I have a lot of options that is why I don''t
want
to use the if else end structure.
Thanks,
David Sousa
