Accessors

hasReadAccess

private get hasReadAccess(): boolean

Source

api/src/services/relations.ts:451

Methods

alterType()

private alterType(table, relation): void

MySQL Specific

MySQL doesn't accept FKs from int to int unsigned. knex defaults .increments() to unsigned, but defaults regular int to int. This means that created m2o fields have the wrong type. This step will force the m2o int field into unsigned, but only if both types are integers, and only if we go from int to int unsigned.

TODO

This is a bit of a hack, and might be better of abstracted elsewhere
