I'm reading the act-as-taggable Github document, https://github.com/mbleigh/acts-as-taggable-on, and I want to force tags to be saved downcase. The instruction in the Configuration section says to add the line
ActsAsTaggableOn.force_lowercase = true
but I'm not quite sure where this would go.
In what file am I supposed to put this piece of code?
Thanks!
