displaying field level validation errors from the backend

Hi, My backend returns validation structured validation errors on post or put, with field level error information for example:

{
    "modelState": {
        "name": "validate error"
    },
    "message": "Name: validate error"
}

{
    "modelState": {
        "name": "validate error"
    },
    "message": "Name: validate error"
}

How can I get the error for the name field to display next to the name field in refine. Is there a specific exception error structure I need to use?

Hi @noam.honig, here is a brief explanation in docs. https://refine.dev/docs/api-reference/core/hooks/useForm/#how-can-invalidate-other-resources

Thanks for getting back to me, I've read the article and I can't find in it what I want looking for. I was hoping for a structure of an exception I as a dataProvider can throw in the create or update that'll be handled by refine to display the error correctly next to the field.

@noam.honig Im so sorry. I sent you wrong link 😦 https://refine.dev/docs/api-reference/core/providers/data-provider/#error-format this is the correct one

Thanks for that. In that error, how do I specify the exact error text I want to display next to each field? Something like:

{
  message:"something is wrong",
  statusCode:500,
  errors:{
    name:"Too Short",
    age:"Too Young"
}
}

{
  message:"something is wrong",
  statusCode:500,
  errors:{
    name:"Too Short",
    age:"Too Young"
}
}

you can write custom form validation and error message like this https://refine.dev/docs/advanced-tutorials/forms/custom-form-validation/

I see - I was hoping for something built in refine that standardizes that as well

🙏 we will release refine 4 in 1 or 2 month. we will definitely consider this Hi @noam.honig, We discussed in the core team. We think your point is really valuable. Thank you 🙏 Do you wanna open feature request on Github ? If you open, we try to speed things up.

Sounds good

Remult looks great, congrats 🙂 Are you creating a dataprovider?

extended-salmon•2y ago

Hi @Omer, yes I'm creating a data provider, it seems fairly simple and powerful @Omer Since you mentioned remult, I would like to ask a follow-up question if that's ok. In remult I have a lot of metadata around the entities (field types, captions, validations etc...) This opens up the opportunity to create a powerful inferer that'll be based on entity metadata rather than JSON results. Is there a simple api for me to use to provide metadata to the refine inferer or do I need to create multiple inferers of my own?
