Rest Framework urls

method: GET
url: /api/v1/assignments/
request params : ?is_done=3&offset=0&limit=5
response: [
        {
            "id": ID,
            "createdAt": Datetime,
            "projectDetails": ProjectDetails
            "createdByDetails": UserDetails
            "contentObjectDetails": ContentDetails(ie lead, entry details)
            "contentType": ID,
            "isDone": Boolean,
            "contentObjectType": str
        }
]

Expected graphql

enum AssignmentContentTypeEnum {
  LEAD
  ENTRY_REVIEW_COMMENT
}

type AssignmentContentDataType {
  contentType: AssignmentContentTypeEnum
  lead: AssignmentLeadDetailType
  entryReviewComment: AssignmentEntryReviewCommentDetailType
}

input AssignmentInputType {
  isDone: Boolean
}

type AssignmentLeadDetailType {
  id: ID!
  title: String!
}

type AssignmentProjectDetailType {
  id: ID!
  title: String!
}

type AssignmentType {
  id: ID!
  createdAt: DateTime!
  createdBy: UserType
  createdFor: UserType!
  project: AssignmentProjectDetailType
  isDone: Boolean!
  objectId: Int!
  contentData: AssignmentContentDataType
}

type AssignmentListType {
  results: [AssignmentType!]
  totalCount: Int
  page: Int
  pageSize: Int
}

type AssignmentUpdate {
  errors: [GenericScalar!]
  ok: Boolean
  result: AssignmentType
}

Note: The client needs to review the lead and entry content types. If contenttype is lead, map data with LeadType; if not, map with EntryType.
