rake create_tables will generate a SQL table creation script to initiate your database.

Always review SQL statements before running against your database.

rake alter_tables will compare a current and prior version of the create_tables output and attempt to highlight the necessary changes. Changes will be listed as add, modify, rename, and drop, and create.

• add columns that have been added
• modify columns that have been modified, likely just the datatype length
• create highlights that a new table was added, and needs to be run from the newer create_tables output.
• rename makes an effort to determine if a column was renamed. However, index changes in the hash can confuse this operation, therefore you should always review all statements returned.
• drop columns that have been removed
• double_check is provided to whenever rename is possible

Always review SQL statements before running against your database.

Consider that the accuracy of alter_tables goes down when the number of changes between files goes up. It's best to stay up to date with master

rake reduce_logs reduces the lines of log files to provide samples of missing data to stream line updating and maintaining the schema.

rake reset_logs will clear the log files.
