The working groups API vs GraphQL representation

[jodator]

We're going to call Working Groups extrinsic from the joystream node API. This means that we have to map a Working Group returned from the Hydra GraphQL server into the proper API namespace.

For instance to apply for a position in the membership Working Group the API call is:

api.tx.membershipWorkingGroup.applyOnPosition()

and for the storage it would be:

api.tx.storageWorkingGroup.applyOnPosition()

It looks like the Working Group's ID will hold the proper name of the Working Group:

type WorkingGroup @entity {
  "Working group id (currently === name)"
  id: ID!

  "Working group name"
  name: String! @unique

  "Working group current metadata"
  metadata: WorkingGroupMetadata

  "Current working group leader"
  leader: Worker

  "Workers that currently belong to the group or belonged to the group in the past"
  workers: [Worker!] @derivedFrom(field: "group")

  "All openings related to this group"
  openings: [WorkingGroupOpening!] @derivedFrom(field: "group")

  "Current working group budget (JOY)"
  budget: BigInt!
}

The other source of this might be Working Group's name.
