Proper JSON type definition to import with a runtime module struct with other struct and enum

Question

I have the following data type defined in my runtime module

#[derive(Encode, Decode, Clone, PartialEq, Debug)]
pub enum AuctionStatus {
  Ongoing,
  Cancelled,
  ToBeClaimed,
  Closed
}

// This is necessary so that other structs depend on this enum can be encode/decode with default value.
impl Default for AuctionStatus {
  fn default() -> Self { AuctionStatus::Ongoing }
}

#[derive(Encode, Decode, Default, Clone, PartialEq, Debug)]
pub struct Auction<Hash, Balance, Moment, AuctionTx> {
  id: Hash,
  kitty_id: Hash,
  base_price: Balance,
  start_time: Moment,
  end_time: Moment,
  status: AuctionStatus,
  tx: Option<AuctionTx>,
}

#[derive(Encode, Decode, Default, Clone, PartialEq, Debug)]
pub struct AuctionTx<Hash, AccountId, Balance, Moment> {
  auction_id: Hash,
  tx_time: Moment,
  buyer: AccountId,
  tx_price: Balance,
}

Now in polkadot UI, what should be the correct JSON type definition to be imported?

I tried the following but polkadotUI is still saying unknown type.

{
  "AuctionStatus": "u32",
  "AuctionTx": {
    "auction_id": "Hash",
    "tx_time": "Moment",
    "buyer": "AccountId",
    "tx_price": "Balance"
  },
  "Auction": {
    "id": "Hash",
    "kitty_id": "Hash",
    "base_price": "Balance",
    "start_time": "Moment",
    "end_time": "Moment",
    "status": "AuctionStatus",
    "tx": "Option<AuctionTx>"
  }
}

Update-01:

The following are the browser console error messages:

not sure if this give any help...

Answer 1

I think the problem here is you have defined your enum as a u32 and it is messing up parsing the encoded data.

From the Polkadot UI help text:

Be aware that the types are registered in the order they appear here. Since Transaction above requires both TransactionInput and TransactionOutput it is defined after the definitions for those are available. (Circular deps are not supported here). For a slightly more complex example, using both types and enums, the following would be used -

{
  "SimpleEnum": {
    "_enum": ["One", "Two", "Three"]
  },
  "TypeEnum": {
    "_enum": {
      "One": "u32",
      "Two": "u64",
      "Three": null
    }
  }.
  "MyNumber": "u32",
  "Thing": {
    "count_enum": "SimpleEnum",
    "type_enum": "TypeEnum",
    "counter": "MyNumber",
    "ids": "Vec<AccountId>"
  },
  "ArrayThing": "Vec<Thing>"
}

So try defining your enum correctly and see if that resolves your issue. Let me know if this helps.
