Direzione di ricerca

Riproduci il fallimento di truncation da una console Rails con tutti e tre gli adattatori JDBC nel Gemfile, quindi esamina database_cleaner-1.0.1/lib/database_cleaner/active_record/truncation.rb intorno alle righe 176 e 209. Confronta il comportamento di caricamento degli adattatori rimuovendo l’adattatore JDBC mysql; il lavoro è completato quando truncation funziona mentre gli adattatori supportati rimangono inclusi nel bundle.

Scritto dal modello di indicizzazione a partire dal testo della issue.

Descrizione

We have an application that needs to support multiple database engines, so our Gemfile contains multiple JDBC adapters as so:

gem 'activerecord-jdbcpostgresql-adapter', '~>1.3.7'
gem 'activerecord-jdbcmssql-adapter', '~>1.3.7'
gem 'activerecord-jdbcmysql-adapter', '~>1.3.7'

The app works as we expect, and each setup with a different database works well, however we've just introduced the mysql adapter, and have now found that the database cleaner is failing to truncate the database.

On my machine, I have a postgres database running. If I open up a rails console, and attempt to clean the database with :truncation I get the following error

TypeError: superclass mismatch for class Mysql2Adapter

We haven't changed any code in our app, and if I comment out the mysql JDBC adapter from the Gemfile and bundle install again, I am once again able to clean the database.

This is the stack trace that I get with the error

It's very similar (exact same error message) to other issues I've found here, however the line numbers are different so I'm assuming the issue is something different, given that the others have also been resolved and this is still appearing.
