This can be useful when + you're building out multiple databases and want to make sure you're not sending + writes when you want a read. + + If `while_preventing_writes` is called and the query is considered a write + query the database will raise an exception regardless of whether the database + user is able to write. + + This is not meant to be a catch-all for write queries but rather a way to enforce + read-only queries without opening a second connection. One purpose of this is to + catch accidental writes, not all writes. + + *Eileen M. Uchitelle* + * Allow aliased attributes to be used in `#update_columns` and `#update`. *Gannon McGibbon* |
