Functions

func AutoMigrate 

func AutoMigrate(dbContext DbContext, ignoreWarnings bool)

AutoMigrate help us do less work in managing the DB migration scripts. It only performs HARMLESS operations, i.e. operations that cannot result in data loss. Amongst these operations: - creation of missing tables - creation of missing link tables - adding of missing columns

  • checking that each property defines a column name (else panic)
  • name consistency checking (this should prevent column renaming) -> the checking should be done by the schema testing

- creation of missing index - extension of column lengths

All the other needed DB operations must be handled by a migration script, that should be written so as to be able to play it anytime, for any version of the app, in order to be free of per-version migration scripts.

func BiContextFromAppServ 

func BiContextFromAppServ(appserv *core.Appserv, dryrun, migrate bool) *appservBiContext

May return an error, and a referencing entity, if there is one.

func DeleteInCache 

func DeleteInCache(biContext BiContext, entity IEntity)

DeleteInCache puts the given entity into the local or global cache, depending on the cache policy set for the corresponding entity kind

func EntityFromCache

func GenericTestAllSchemas 

func GenericTestAllSchemas() (item string, required string, message string, ok bool)

GenericTestAllSchemas tests that all the entities registered through corresponding resources (cf. init function in WS files) have each a correct schema This allows to detect bad entity coding, i.e.: - using non-pointer references to other entities - using non-entity links - using fields of unknown kinds - unqualified entity links, i.e.

  • with no link owner type,
  • missing backref info (can be void, i.e. if no backref)
  • bad backref (not pointing back to the right entity kind)

The returned object is made to be used with the light testing framework goblin: 

g := goblin.Goblin(t)
r := GenericTestAllSchemas()
g.Describe(r.Item, func() { g.It(r.Required, func() { g.Assert(!r.Failed).IsTrue(r.Message) }) })

NB: in this function, we can observe the advantage of Go's capability to name returns, since it's way more compact this way
