Rails：即使默认值设置为0，枚举字段仍为零

Question

I have defined following enum fields in my model:

class ClientRegistration < ApplicationRecord
  enum status: { pending: 0, registered: 1, activated: 2, suspended: 3 }
  enum cloud_type: { onprem: 0, aws: 1, gcp: 2, azure: 3 }
end

The migration file for the same looks like below:

class CreateClientRegistrations < ActiveRecord::Migration[5.2]
  def change
    create_table :client_registrations do |t|
      t.string :instance_id
      t.string :private_ip
      t.string :mac_address
      t.integer :cloud_type, default: 0
      t.string :public_ip
      t.string :region
      t.integer :status, default: 0

      t.timestamps
    end
  end
end

Now the strange thing is, my first column status doesn't get it's default value if I don't specify any. Also it doesn't take the first value if I specify explicitly as pending . But it works in case of my second column cloud_type , it gets the default as onprem , if I don't specify any. Do I need to change the column_name or so?

You can try to add "null: false" to the migration.

  t.integer :cloud_type, null: false, default: 0

  t.integer :status, null: false, default: 0
