从 JSON 创建动态 Yup 验证模式

Question

我正在尝试在我的反应形式中使用Yupwith Formik。表单字段将是动态的，以便进行验证。

export const formData = [
  {
    id: "name",
    label: "Full name",
    placeholder: "Enter full name",
    type: "text",
    required: true,
    value: "User name",
    values: [],
    validations: [
      {
        type: "minLength",
        value: "5",
        error_message: "name should be atleast 5 char long"
      },
      {
        type: "maxLength",
        value: "10",
        error_message: "name should be atleast 5 char long"
      }
    ]
  },
  {
    id: "email",
    label: "Email",
    placeholder: "Email",
    type: "text",
    required: true,
    value: "email",
    values: [],
    validations: [
      {
        type: "minLength",
        value: "5",
        error_message: "name should be atleast 5 char long"
      },
      {
        type: "maxLength",
        value: "10",
        error_message: "name should be atleast 5 char long"
      },
      {
        type: "email",
        error_message: "Valid email"
      }
    ]
  },
  {
    id: "phoneNumber",
    label: "phone number",
    type: "text",
    required: true,
    value: "7878787878",
    values: [],
    validations: [
      {
        type: "minLength",
        value: "5",
        error_message: "name should be atleast 5 char long"
      },
      {
        type: "maxLength",
        value: "10",
        error_message: "name should be atleast 5 char long"
      },
      {
        type: "required",
        error_message: "phone number is required"
      }
    ]
  },
  {
    id: "total",
    label: "Total People in Family",
    placeholder: "family members count",
    type: "text",
    required: false,
    value: "1",
    values: [],
    validations: [
      {
        type: "minLength",
        value: "1",
        error_message: "there should be atleast 1 family member"
      },
      {
        type: "maxLength",
        value: "5",
        error_message: "max family members can be 5"
      }
    ]
  }
]

 let validateSchema = yup.object().shape({
     name: yup.string().required("name is required"),
     email: yup.string().email(),
     phoneNumber: yup.number().min(10, "minium 10 numbers"),
     total: yup
       .number()
       .min(1, "minium 1 member")
       .max(5, "max 5 member")
       .required("member is required")    });

• 我目前正在做的是迭代上述数组并调用相应的 React 表单组件。
• 验证目前由 处理Yup。我知道你可以像上面的 `validateSchema' 变量一样创建静态 Yup 验证模式。
• 现在我想根据formData.validation数组中的值创建这个验证模式。我在这个codeandbox中尝试了一些方法， 但仍然无法弄清楚。此外，我调查了Yup.lazy但对我来说似乎非常混乱。

任何帮助将不胜感激 ：）

以防有人试图动态创建yupschema。在一些帮助下，我能够做到。

import * as yup from "yup";

export function createYupSchema(schema, config) {
  const { id, validationType, validations = [] } = config;
  if (!yup[validationType]) {
    return schema;
  }
  let validator = yup[validationType]();
  validations.forEach(validation => {
    const { params, type } = validation;
    if (!validator[type]) {
      return;
    }
    console.log(type, params);
    validator = validator[type](...params);
  });
  schema[id] = validator;
  return schema;
}
