Ecto.Multi
Ecto.Multi
Ecto.Multi is a data structure for grouping multiple Repo operations.
Ecto.Multi makes it possible to pack operations that should be performed in a single database transaction and gives a way to introspect the queued operations without actually performing them. Each operation is given a name that is unique and will identify its result in case of success or failure.
All operations will be executed in the order they were added.
The Ecto.Multi structure should be considered opaque. You can use %Ecto.Multi{} to pattern match the type, but accessing fields or directly modifying them is not advised.
