如何覆盖 GovernorCountingSimple.sol 文件中的 openzeppelin _countVote 函数?
how to override openzeppelin _countVote function in GovernorCountingSimple.sol file?
我正在使用 openzeppelin 创建一个 DAO,我从 openzeppelin 合同向导下载了他们提供的治理合同。一旦我将这个文件导入到 remix IDE 中,就会弹出一个错误提示
“函数必须覆盖指定但不覆盖任何东西”
所以我按照那个错误找到了 GovernorCountingSimple.sol 文件,发现它是 _countVote 函数,但我似乎无法覆盖它。我想我只是遗漏了一些简单的东西,但是当函数中的最后一个参数是没有声明名称的“字节内存”时,我不知道如何重写它,而且我似乎不能只调用函数上的 super 语句来传递最后一个参数。

您离解决方案更近了...
只需更改此行:super._countVote(proposalId,account,support,weight,*);
不要使用此符号 *
来省略最后一个参数,请尝试使用单引号。
这应该有效:
super._countVote(proposalId,account,support,weight,'');
