Problem

(See #266)

For a given multi-pitch climb, for each pitch, we want to represent multiple boltsCount and grades, e. g. grade = ["6a", "6c", "5c", "6c"], and boltsCount = [4, 6, 3, 3], and possible other data (like description).

Solution

Introduce type Pitch (with fields parentId, type, number, grade, length, boltsCount, description) as a child to climb, so that climb gets an optional Array Climb.pitches containing each pitch; this has the most flexibility and allows for detailed per-pitch data, plus it wouldn't break any existing implementation

Example JSON Doc Schema

type Climb {
  id: ID!
  uuid: ID!
  name: String!
  ...
  pitches: [Pitch]!  # new pitches array of type Pitch
}

The Type Pitch would contain:

type Pitch {
  uuid: ID!
  parentId: ID!
  number: Int!
  grades: GradeType!
  type: ClimbType!
  length: Int!
  boltsCount: Int
  description: String
}
