logging: e => logger('sequelize').info(e)

这会记录如下结果：

INSERT INTO "test" ("id","aa","bb","cc") VALUES (DEFAULT,$1,$2,$3) RETURNING *; // I don't want this

如何更改以使输出像这样？

INSERT INTO "test" ("id","aa","bb","cc") VALUES (DEFAULT,"AA","BB","CC") RETURNING *; // I want this 

我在反应功能组件中有以下代码。当我单击按钮并运行处理程序时，发生错误： Invalid hook call. Hooks can only be called inside of the body of a function component.

const handleClick = () => {
  const [count, setCount] = useState(x); // this is wrong

const [count, setCount] = useState(0);

const handleClick = () => {
  setCount(x); // setCount is ok, but I cannot set other dynamic states
};

但是，我的count状态是动态的，我无法从一开始就全部初始化。当我使用类组件时，这很容易。

// old syntax from class components
state = {
  count: 0
};

const handleClick = () => {
  this.setState({ …
