I modified a model so it includes a new field, such as...
field :url, :type => String
I use activeadmin, so when I create a new entry @model.url
is empty, and in entries created before changing the schema it's nil. How do I select both? I have tried:
# Returns nils and strings
Model.where(:url.ne => "").count
# Returns strings and ""
Model.where(:url.ne => nil).count
# Returns strings, nils and ""
Model.where(:url.ne => ["", nil]).count
Or, if there's a best practice for this kind of scenario please let me know.
