Interesting Things
ActiveRecord::Base.connection.select_all reads all records into an array, which is not good if you have a very large result set. Use a combination of ActiveRecord::Base.connection.execute with .each, or .each_hash if you want the same column<=>value mappings you get with select_all, only streamed.
There was some confusion about BlueCloth:
- There's a gem and a plugin available, and it appears that you need to use both
- It seems like the only live BlueCloth development (i.e. where patches should be sumbitted) is here: http://github.com/github/bluecloth/tree/master
A recent MySql trigger experience:
- In summary, think twice before using them when you have a viable application code alternative
- They're not cloned from the dev to test database
- The hosting provider this project is using requires that we submit a change request each time we want to add/change/delete triggers. The problem with that is your trigger changes aren't in sync with your code deployments.
- It wasn't hard to write the application code
During a discussion about humanize, a couple other nifty transforms were mentioned:
- parameterize: You have a string, and you want to strip out characters that aren't url-friendly. (follow the link for good example/discussion)
- auto_link a Rails helper that takes text and links up all urls and email addresses.
For Markdown, there are several newer/faster alternatives to BlueCloth, recorded here.
