Inconsistent enum behavior

[leviwilson]

We have a model where the import behavior is inconsistent in populating an enum value with the INSERT INTO statement where sometimes it has it, and other times it does not.

Here is the model definition:

class SelectionField < Field
  after_initialize { |field| field.input_type = :selection }

  enum presentation: %i[dropdown multi_select radio_group]
end

If I try to import them directly in one context, you can see that rather than setting 0 for the enum it sets NULL (it doesn't make a difference if I choose a different value):

irb(main):001:0> Field.import!([field = SelectionField.new(presentation: 'dropdown')]); field.reload.presentation

=> nil

But in other contexts like doing a recursive: true it does get it

Just trying to think through anything to try that might drive this behavior.
