Zod overrides react-hook-form validation

I have the following form scheme. When I specify rules={{required: true}} on the field it doesn't work because of zod validation scheme.

const trendyolFormScheme = z.object({
  brand: z.string().optional(),
  attributes: z.array(
    z
      .object({
        attributeId: z.number(),
        customAttributeValue: z.string().optional(),
        attributeValueId: z.number().optional(),
      })
      .optional(),
  ),
});

const trendyolFormScheme = z.object({
  brand: z.string().optional(),
  attributes: z.array(
    z
      .object({
        attributeId: z.number(),
        customAttributeValue: z.string().optional(),
        attributeValueId: z.number().optional(),
      })
      .optional(),
  ),
});

I want to be able to override Zod or being able to make field required based on api response (later on).

Solution:

And as you mentioned you can make it required based on api response, you can use a discriminated union to make things required depending on some data from the api https://zod.dev/?id=discriminated-unions

Zod is your validation, so if you want things to be required, they have to be done on the schema. Or at least you can create a required version of that schema by calling .required();

const requiredTrendyolFormScheme = trendyolFormScheme.required();

const requiredTrendyolFormScheme = trendyolFormScheme.required();

Sounds like you want to run some manual validations first and then parse it with a stricter zod schema. Is that the case? Alternatively you could make it required initially and then handle parsing errors however you want.

I used discriminatedUnion and refined. It wasn't the cleanest thing but it does the job. Thanks 🙏. Thanks for your suggestion
