The subtle difference between these two eluded me for a while, so for those who are just getting started in Rails this tip may be helpful.
If you want to ensure that no ActiveRecord validation errors, etc. were generated when saving a model, do a:foo.save!If you do the following instead:
foo.save
The method will return false but an exception will not be generated. I’ve debugged several hair-pulling issues that could’ve been avoided by calling “save!” .
