React hook form and zod inumber input
问题
我使用React Hook Form创建了一个表单，并使用Zod进行了验证。在一个输入框中，我想输入数字，但当我输入任何数字时，错误消息显示它不是数字：
<Controllername="calories"control={control}defaultValue={1}render={({ field }) => (<input{...field}type="number"className="w-full px-3 py-2 border rounded-md"/>)}
calories: z.number({required_error: "卡路里是必填项",invalid_type_error: "卡路里必须是数字",}).int().positive().min(1, { message: "卡路里至少应为1" }),
我是否漏掉了什么？
未找到解决方法。
英文:
I have created a form with react hook form and did a validation with zod. In one input I want to write in numbers, when I write any number, the error says it is not a number:
<Controllername="calories"control={control}defaultValue={1}render={({ field }) => (<input{...field}type="number"className="w-full px-3 py-2 border rounded-md"/>)}
calories: z.number({required_error: "Calories is required",invalid_type_error: "Calories must be a number",}).int().positive().min(1, { message: "Calories should be at least 1" }),
I am missing something?

当输入的类型为number时，即使用户输入数字，它也会将其值发送为string。结果，Zod将该值视为string并认为它无效，不符合number()验证。
我不熟悉Zod，但这里的想法是，在应用Zod验证之前，如果可以的话，您需要将输入值转换为数字，否则将其验证为一个应该是有效数字的字符串，可以参考这里。
英文:
When the input is of type number, it sends its value as a string even if the user inputs a number.<br> As a result, Zod sees the value as a string and considers it invalid for the number() validation.
I am not familiar with Zod but the idea here is that before applying the Zod validation, if you can, you'll need to convert the input value to a number otherwise validate it as a string that should be a valid number have a look here

我找到了来自Ahmed Sbai的解决方案，在这里
最终解决方案如下：
calories: z.preprocess((a) => parseInt(z.string().parse(a), 10),z.number().positive().min(1)),

I found the solution that was given from Ahmed Sbai from here
End solution is this:
calories: z.preprocess((a) => parseInt(z.string().parse(a), 10),z.number().positive().min(1)),
