如何使用动态字段名称创建 Formik YUP 架构?

How do you Create a Formik YUP Schema with Dynamic Field Names?

如何使用动态点表示法字段名称创建 YUP 架构?以下架构无效。我将如何遍历 Costs.0.item、Costs.1.item、Costs.2.item AND Costs.0.amount、Costs.1.amount、Costs.2.amount动态?感谢您的帮助!

const IpSchema = Yup.object().shape({

        Project_Title: Yup.string()
            .min(2, 'Too Short!')
            .max(255, 'Too Long!')
            .required('Required'),
        Costs.0.item: Yup.string()
            .min(2, 'Too Short!')
            .max(255, 'Too Long!')
            .required('Required'),
        Costs.1.item: Yup.string()
            .min(2, 'Too Short!')
            .max(255, 'Too Long!')
            .required('Required'),
        Costs.2.item: Yup.string()
            .min(2, 'Too Short!')
            .max(255, 'Too Long!')
            .required('Required'),
        Costs.0.amount: Yup.string()
            .min(2, 'Too Short!')
            .max(255, 'Too Long!')
            .required('Required'),
        Costs.1.amount: Yup.string()
            .min(2, 'Too Short!')
            .max(255, 'Too Long!')
            .required('Required'),
        Costs.2.amount: Yup.string()
            .min(2, 'Too Short!')
            .max(255, 'Too Long!')
            .required('Required'),

    });

在这种情况下您必须使用 yup.array,即:

const IpSchema = Yup.object().shape({
  Project_Title: Yup.string()
                    .min(2, 'Too Short!')
                    .max(255, 'Too Long!')
                    .required('Required'),
  Costs: Yup.array().of(
    Yup.object({
      item: Yup.string()
               .min(2, 'Too Short!')
               .max(255, 'Too Long!')
               .required('Required')
      amount: Yup.string()
                 .min(2, 'Too Short!')
                 .max(255, 'Too Long!')
                 .required('Required')
    })
  ),
});

如果您将 YUPformik 一起使用,您可以检查 this. On docs provided example. And otherwhise according docs 您可以这样做:

const IpSchema = Yup.object().shape({
  Project_Title: Yup.string()
                    .min(2, 'Too Short!')
                    .max(255, 'Too Long!')
                    .required('Required'),
  Costs: Yup.array().of(
              Yup.object()
                    .shape({
                      item: Yup.string()
                        .min(2, 'Too Short!')
                        .max(255, 'Too Long!')
                        .required('Required'),
                      amount: Yup.string()
                        .min(2, 'Too Short!')
                        .max(255, 'Too Long!')
                        .required('Required')
                    })
                ),
});
