PostgreSQL tetikleyiciler (RSpec çalışırken)

Question

Ben PostgreSQL'in yerleşik mekanizmasını kullanarak benim Raylar app tam metin aramasını uygulayan test ortamında denilen değildir. Benim indeksi her ekleme/güncellemeden sonra güncellenmesini sağlamak amacıyla aşağıdaki göç oluşturduk:

O/kuyu geliştirme üretimini çalışır.

sorun tetik ben gözlük çalıştırıyorum zaman (RSpec tabanlı, Veritabanı Temizleyici temizleme DB için kullanılır) olarak adlandırılan olmamasıdır.

tetikleyiciler nedeniyle Veritabanı Temizleyici aktivite, başlangıçta devre dışı olsa da, bunlar gerçek testi önce tekrar etkinleştirilir:

Bu tam metin arama dizini kullanmak için bir girişimde bulunmaz spec tam bir günlüktür koşar. gelişmede

/üretim oluşturduktan sonra/rekor güncellenmesi, Parça no search_vector verileri içerir. Testte her zaman sıfırdır.

Neyi yanlış yapıyorum?

Answer 1

Bir :deletion stratejisini (DatabaseCleaner.clean_with(:deletion) ve DatabaseCleaner.strategy = :deletion) kullandığınızdan emin olun. :truncate kullanırsanız, benim tahminim temel olarak tabloyu yeniden oluşturacak ve bunu yaparken tablo tetikleyicisini yeniden oluşturmayacaktır.

Postgresql Truncation speed

A TRUNCATE size onlar sadece CREATEed sanki tamamen yeni bir tablo ve dizin verir bakınız. Tüm kayıtları sildiniz, tablosunu yeniden doldurup bir vakum doldu.

Bunun sizin için çalışır umut - benim için çalışıyor.
