Reset table cache?

[Bonne Eggleston]

Hi there,

I'm using database_cleaner in an app which regularly adds and removes tables from the schema. I'm running into issues where database_cleaner tries to truncate a table that's already been dropped. I can reset the global table cache, but I believe database_cleaner maintains its own cache.

Would anyone know an easy way to reset that cache (or a workaround), or would I need to patch database_cleaner?

I should mention that I don't know the name of the new/dropped tables beforehand so I can't just filter them out. 

Thanks,
