I want to display published posts that are tagged using will_paginate.
Options include:
1. Add :conditions => { :published => true } to the find options. Does not
work because will_paginate will then return too many records.
2. Use scope_out in class Post like this:
scope_out :published, :conditions => { :published => true }
Controller:
def tagged_with
@tag = params[:id]
# Thanks go out to http://blog.wolfman.com/posts/33
options = Post.find_options_for_find_tagged_with(@tag).merge(:page =>
params[:page], :per_page => property(:items_per_page))
#...@posts = Post.paginate(options)
@posts = Post.paginate_published(options)
redirect_to :action => :tag_not_found if @Posts.empty?
# Create a new comment in memory
@comment = Comment.new( :Post => @Post)
end
But this yields the error:
test_show_nonpublished_posts(FrontendControllerTest):
ActiveRecord::RecordNotFound: Couldn't find Post without an ID
/usr/lib/ruby/gems/1.8/gems/activerecord-2.3.2/lib/active_record/base.rb:1572:in

Any ideas why?
