Model Annotation Not Updated When Modifying Table Columns Using change_table.

[hatsu38]

Describe your problem here.

Commands

class RemoveOtherColumnsFromQuestionAnswers < ActiveRecord::Migration[7.2]
  def up
    change_table :question_answers, bulk: true do |t|
      t.remove :use_scene
      t.remove :important_point
      t.remove :remark
      t.remove :link
    end
  end

  def down
    change_table :question_answers, bulk: true do |t|
      t.text :use_scene, default: "", null: false, comment: "利用シーン"
      t.text :important_point, default: "", null: false, comment: "重要ポイント"
      t.text :remark, default: "", null: false, comment: "備考"
      t.string :link, default: "", null: false, comment: "リンク"
    end
  end
end

^ I wrote the above migration file and migrated it. bundle exec rails db:migrate

❯ ber db:migrate 
== 20241128110218 RemoveOtherColumnsFromQuestionAnswers: migrating ============
-- change_table(:question_answers, {:bulk=>true})
   -> 0.0046s

Annotating models
Model files unchanged.

^ Normally, it should result in a model change, but it displayed Model files unchanged. instead. This sometimes happens when modifying a table, but it doesn't occur when creating a table.

Detail

I understood what was happening. I knew why.

It doesn't seem to work when the table information contains anything other than English and numbers.

Post.rb

# == Schema Information
#
# Table name: posts
#
#  id              :uuid             not null, primary key
#  title(タイトル) :string           not null
#  content(内容)   :text             not null
#  created_at      :datetime         not null
#  updated_at      :datetime         not null
#
class Post < ApplicationRecord
end

And, I generate migration file.

class AddMemoToPost < ActiveRecord::Migration[7.2]
  def change
    add_column :posts, :memo, :text, comment: "メモ"
  end
end

I do migrate.

❯ ber db:migrate
== 20241201063248 AddMemoToPost: migrating ====================================
-- add_column(:posts, :memo, :text, {:comment=>"メモ"})
   -> 0.0159s
== 20241201063248 AddMemoToPost: migrated (0.0161s) ===========================

Annotating models
Model files unchanged.

-> Model files unchanged.

But, If I don't use Japanese, I use English comment.

class AddMemoToPost < ActiveRecord::Migration[7.2]
  def change
-    add_column :posts, :memo, :text, comment: "メモ"
+    add_column :posts, :memo, :text, comment: "memo"
  end
end

And I do migrate!

❯ ber db:migrate
== 20241201063248 AddMemoToPost: migrating ====================================
-- add_column(:posts, :memo, :text, {:comment=>"memo"})
   -> 0.0039s
