metabase.models.dependency — metabase-core 1.0.0-SNAPSHOT

Dependencies are used to keep track of objects that depend on other objects, and acts as a sort of m2m FK table. For example, a Card might use a Segment; a Dependency object will be used to track this dependency so appropriate actions can take place or be prevented when something changes.

Dependency clj

(Dependency)

(Dependency id)

(Dependency & kvs)

Entity for 'dependency' table; instance of DependencyInstance.

IDependent clj protocol

Methods an entity may optionally implement to control how dependencies of an instance are captured.

dependencies clj

(dependencies this id instance)

Provide a map of dependent models and their corresponding IDs for the given instance. Each key in the returned map must correspond to a valid Metabase entity model otherwise it will be ignored. Each value for a given key should be a collection of unique integer ids for the given model.

For example: (dependencies Card 13 {}) -> {:Segment [25 134 344] :Table [18]}

retrieve-dependencies clj

(retrieve-dependencies entity id)

Get the list of dependencies for a given object.

update-dependencies! clj

(update-dependencies! entity id deps)

Update the set of Dependency objects for a given entity.
