similar to: undefined method `comment_count' for YouTubeG

This is how I''m posting comments currently. This works, but I read somewhere that I shouldn''t inject params right into my sql query, because it makes it easy for people to hack in and ruin the db. I''m not sure if this even makes sense, but I''ve tried other things, and can''t get anything else to work. #currently def comments content =

I have recently upgraqded to Ruby 1.9.2-rc1 and reinstalled rails 3 beta 4 with all the dependencies. I have run bundle install in my rails project. Now I am trying to run some tests... My test_helper.rb file looks like this: # test_helper.rb require ''rubygems'' require ''test/unit'' require ''rails/all'' $ gem list i18n (0.4.1, 0.3.7)

The method is here: https://github.com/rails/rails/blob/master/activerecord/lib/active_record/persistence.rb#L288.

ActiveRecord::StatementInvalid: Mysql::Error: Lock wait timeout exceeded; try restarting transaction: UPDATE `posts` SET `updated_at` = ''2010-03-17 05:35:00'', `view_count` = 54 WHERE `id` = 158 Googling around, I found that this is basically because the transaction times out after

I''m trying to post comments using Ajax. It seems that I have an infinite loop somewhere, because it hangs on the return from the Ajax call. The comment does get saved to the DB, but I have to refresh the page for it to show. The reason I know it''s some sort of infinite loop, is because I''m showing a "loading.gif" image, and it never goes away. Plus, if
