TypeError:在地址payable[]存储参考文件中的依赖于参数的查找之后，找不到成员"push“或不可见

Question

当我将新创建的契约地址推入contracts[]数组时，出现了上述错误。我哪里出问题了？任何帮助都将不胜感激。

pragma solidity ^0.8.0;

contract Bakery {

  // index of created contracts

  address[] public contracts;
  Cookie public cookieContract;

  function getContractCount() 
    public
    
    returns(uint contractCount)
  {
    // return contracts.length;
  }

  // deploy a new contract

  function newCookie(string memory _name)
    public
    returns(Cookie newContract)
  {
    newContract = new Cookie(_name);
    contracts.push(newContract);   ///**Line Having Error***//////
    return newContract;
  }

  function getCookieName (Cookie _cookieContract) public returns(string memory name) {
      cookieContract = _cookieContract;
      string memory n =  cookieContract.name();
      return n;
  }
}


contract Cookie {

    //name
    string public name;

     constructor (string memory _name) public{
        name = _name;
    }

  // suppose the deployed contract has a purpose

  function getFlavor()
    public
    pure
    returns (string memory flavor)
  {
    return "mmm ... chocolate chip";
  }    
}```

Answer 1

问题是contracts被声明为

address[] public contracts;

所以它只接受地址。

您可以通过将newContract转换为地址来修复它。

function newCookie(string memory _name)
  public
  returns(Cookie newContract)
{
  newContract = new Cookie(_name);
  contracts.push(address(newContract));
  return newContract;
}
