Reason 原因组件中未绑定的记录字段名称

Reason 原因组件中未绑定的记录字段名称,reason,reason-react,Reason,Reason React,借用Yawar的所有有用信息,我有以下几点: $cat src/index.re let products = [| {name: "Football", price: 49.99}, {name: "Basebll", price: 1.99}, {name: "Poker", price: 33.99} |]; ReactDOMRe.renderToElementWithId( <ProductTable products /> ); $cat src/

借用Yawar的所有有用信息,我有以下几点:

$cat src/index.re 
let products = [|
  {name: "Football", price: 49.99},
  {name: "Basebll", price: 1.99},
  {name: "Poker", price: 33.99}
|];

ReactDOMRe.renderToElementWithId(
    <ProductTable products />
);

$cat src/productRow.re
let component = ReasonReact.statelessComponent("ProductRow");

let echo = ReasonReact.stringToElement;

let make = (~name: string, ~price: float, _) => {
 ...component,
 render: (_) => {
    <tr>
     <td>{echo(name)}</td>
     <td>{price |> string_of_float |> echo}</td>
    </tr>
 }
};
$cat src/ProductTable.re
let component = ReasonReact.statelessComponent("ProductTable");

let echo = ReasonReact.stringToElement;

let make = (~products, _) => {
    ...component,
    render: (_) => {
      let productRows = products
        |> Array.map(({name, price}) => <ProductRow key=name name price />)
        |> ReasonReact.arrayToElement;

      <table>
        <thead>
          <tr>
            <th>{echo("Name")}</th>
            <th>{echo("Price")}</th>
          </tr>
        </thead>
        <tbody>productRows</tbody>
      </table>
    }
}
$cat src/index.re
让产品=[|
{名称:“足球”,价格:49.99},
{名称:“Basebll”,价格:1.99},
{名称:“扑克”,价格:33.99}
|];
ReactDOMRe.renderToElementWithId(
);
$cat src/productRow.re
让component=ReasonReact.statelementComponent(“ProductRow”);
让echo=ReasonReact.stringToElement;
让make=(~name:string,~price:float,))=>{
组成部分
渲染:())=>{
{echo(名称)}
{price |>string_of_float |>echo}
}
};
$cat src/ProductTable.re
让component=ReasonReact.statelementComponent(“ProductTable”);
让echo=ReasonReact.stringToElement;
让make=(~products,)=>{
组成部分
渲染:())=>{
让productRows=产品
|>map(({name,price})=>)
|>ReasonReact.array元素;
{echo(“Name”)}
{echo(“价格”)}
productRows
}
}
我得到以下编译时错误:

   7 ┆ render: (_) => {
   8 ┆   let productRows = products
   9 ┆     |> Array.map(({name, price}) => <ProductRow key=name name price />
       )
  10 ┆     |> ReasonReact.arrayToElement;
  11 ┆ 

  Unbound record field name
7┆ 渲染:())=>{
8.┆   让productRows=产品
9┆     |> Array.map(({name,price})=>
)
10┆     |> ReasonReact.array元素;
11┆ 
未绑定记录字段名

如何修复此编译时错误?

编译器将为您推断许多类型的原因,但对于记录,您必须首先声明它有哪些字段(及其类型)

根据@yawar的有用答案,您只需在文件顶部包含类型定义:

type product={name:string,price:float};


有了这一点,编译器将能够分辨出
产品
属于
数组(产品)
类型,并且应该从那里愉快地继续下去。试试看
