问题将值推送到结构中的枚举数组

Question

我正在尝试将值推送到存储在结构中的枚举数组，但我无法推送值。我哪里错了？这是我的代码：

// SPDX-License-Identifier: UNLICENSED

pragma solidity 0.8.12;

contract Test {
    address private owner; // owner is Insurance Company

    mapping (address => Record) records;
    enum Animal {Lion, Tiger, Zebra}

    struct Record {
        Animal[] animal; // status of the record
    }

    constructor() { // set owner on deploy as deployer address
        owner = msg.sender;
    }

    function addRecord() public {
        Record storage record = records[msg.sender];
        record.animal.push(0);
        // record.animal[0] = Lion;
        // record.animal = [Lion, Tiger};
    }
}

我的错误：

TypeError: Member "push" not found or not visible after argument-dependent lookup in enum Test.Animal[] storage ref.
--> b.sol:21:9:
|
21 | record.animal.push(0);
| ^^^^^^^^^^^^^^^^^^

Answer 1

试试这个：

record.animal.push(Animal.Lion);
