0.3a19

  • [bug] Fixed "price toggle" bug in database sync. It was noticed that whenever a product's regular price did not change, yet the product instance itself did have a change, the regular price association was being removed in one sync, then reestablished in the next sync (then removed, etc.). The sync operation now ensures the relationship is removed only when it really should be, and that it remains intact when that is appropriate.

0.3a18

  • [bug] Added special delete logic to the database sync. Currently, only the Department and Subdepartment classes are affected. When deletions of these classes are to be synced between databases, some effort is made to ensure that associations with any dependent objects (e.g. Product) are removed before the primary instance (e.g. Department) is deleted.

0.3a17

  • [bug] Added 'delete, delete-orphan' to cascade on Product.costs relationship. This was causing an error when syncing databases.

0.3a16

  • [bug] Added 'delete, delete-orphan' to cascade on Product.prices relationship. This was causing an error when syncing databases.

0.3a15

  • [bug] Fixed database sync logic to ensure Product changes are processed before ProductPrice changes. Since the underlying tables are mutually dependent, the dependency_sort() call can't quite take care of it. Now a lexical sort is applied to the class names before the dependency sort happens. This is somewhat of a hack, merely taking advantage of the fact that "Product" comes before "ProductPrice" when lexically sorted. If other mutually-dependent tables come about in the future, this approach may need to be revised if their class names don't jive.

0.3a14

  • [bug] Fixed database synchonization logic to properly handle merging Product instances between database sessions. Since Product is so interdependent on ProductPrice, a pretty custom merge hack is required.

0.3a13

  • [bugfix] Fixed rattail.db.record_changes() so that it also ignores UserRole instance changes if configuration dictates that Role changes are to be ignored.

0.3a12

  • [bugfix] Fixed foreign key uuid handling in rattail.db.record_changes(). Some tables are meant to be used solely as providers of "association proxy" fields, the uuid column is not only a primary key, but also a foreign key to the "primary" entity table. In such cases, the uuid value was not present at session flush time, so a new one was being generated. Unfortunately this meant that the Change record would point to a nonexistent entity record, so the sync would not work. Now uuid fields are inspected to determine if a foreign key is present, in which case the relationship is traversed and the true uuid value is used.
  • [feature] Added "extra classes" configuration for the load-host-data command. This is necessary when initially populating a "store" (er, "non-host") database instance if custom schema extensions are in use (and need to be synchronized with the host).
