RoR：SQLite3 :: ConstraintException：制約に失敗しました=> rake db：seed

Question

rake db:seedを実行すると、何かが壊れています！

私は次のエラーを取得する：

ray@ray-virtual-machine:~/ticketee$ rake db:seed rake aborted! SQLite3::ConstraintException: constraint failed: INSERT INTO "users" ("admin", "confirmation_sent_at", "confirmation_token", "confirmed_at", "created_at", "current_sign_in_at", "current_sign_in_ip", "email", "encrypted_password", "last_sign_in_at", "last_sign_in_ip", "remember_created_at", "reset_password_sent_at", "reset_password_token", "sign_in_count", "updated_at") VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)

Tasks: TOP => db:seed (See full trace by running task with --trace)

ここに私のseeds.rb：

admin_user = User.create(:email => "admin@ticketee.com", :password => "password") admin_user.admin = true

admin_user.confirm!

Project.create(:name => "Ticketee Beta")

Tasks: TOP => db:seed 

私のコードで何が起こったのか教えていただけますか？私は新しいです。

ありがとうございます。

Answer 1

私の推測では、あなたが呼び出すときに必要なすべてのフィールドを提供していないということです。

admin_user = User.create(:email => "admin@ticketee.com", :password => "password") 

テーブルのユーザーのためのマイグレーションファイルはどのようなものが見えますか？ モデルユーザーに入力した検証は何ですか？

Answer 2

私のモデルには 'has_many'検証があるので、トレース<top (required)>と同じエラーが発生しました。 has_manyまたはbelongs_toがusers.rbファイルのどこかにあり、を実行できないことを確認してください。コメントアウトしてシードし、コメントを外します。

Answer 3

テストを実行している間に私が挿入したレジスタがいくつかあったため、test.sqlite3、development.sqlite3、schema.rbファイルを削除して、移行したデータベースを実行してDBをシードしました。
