How do I fetch all 'link' entries exept those with an 'url' column that is blank? My controller looks like this:
def show
@user = User.find_by_username(params[:username])
@links = @user.links.all
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @links }
end
end
Thanks in...
