javascript - 如何通过单个 react 选择正确使用 Yup 模式？

Question

我正在使用 react-select 与 Formik 和 Yup 来验证我的表单，但由于某种原因我的验证不起作用。我的架构如下所示:

const Schema = Yup.object().shape({
age: Yup.object().shape({
    label: Yup.string().required("Required"),
    value: Yup.string().required("Required")
})
});

我的数据如下所示:

export const ageOptions = [
  { value: 0.1, label: "Not born yet" },
  { value: 0.3, label: "Baby - 0 to 3 months" },
  { value: 0.6, label: "Baby - 3 to 6 months" },
  { value: 0.12, label: "Baby - 6 to 12 months" },
  { value: 0.18, label: "Baby - 12 to 18 months" },
  { value: 0.24, label: "Baby - 18 to 24 months" },
  { value: 2, label: "2 years" },
  { value: 3, label: "3 years" },
  { value: 4, label: "4 years" },
  { value: 5, label: "5 years" },
  { value: 6, label: "6 years" },
  { value: 7, label: "7 years" },
  { value: 8, label: "8 years" },
  { value: 9, label: "9 years" },
  { value: 10, label: "10 years" },
  { value: 11, label: "11 years" },
  { value: 12, label: "12 years" },
  { value: 13, label: "13 years" },
  { value: 14, label: "14 years" }
];

当我在 UI 内的选择中选择一个选项时，返回以下错误:

age must be a `object` type, but the final value was: `null` (cast from the value `0.6`). If "null" is intended as an empty value be sure to mark the schema as `.nullable()`

如何使验证正确进行？

您要求 age 为 object 类型，但将其设置为所选选项的值。这就是触发您错误验证的原因。以下是修复验证的方法:

1. 如果您希望将 age 保留为一个对象，请将架构更改为以下内容:

const Schema = Yup.object().shape({
    age: Yup.object().shape({
        label: Yup.string().required("Required"),
        value: Yup.string().required("Required")
    })
});

否则将其设置为以下内容:

const Schema = Yup.object().shape({
    age: Yup.string()
});

更新 Select 组件上的 onChange，将值设置为 option 而不是 option.value 如果您想在架构验证中使用该对象。

<Select
    { ... }
    value={field.value} // This can be set like this as a result of the change
    onChange={option => form.setFieldValue(field.name, option)}
/>

这应该可以让它工作。
