More fine grained control? about ajv-errors

[epoberezkin]

That's what is there in the link you posted (and that's how you can use it):

{
  "type": "object",
  "properties": {
    "size": {
      "type": "number",
      "minimum": 4,
      "errorMessage": {
        "type": "Size must be a number",
        "minimum": "Size cannot be less than 4"
      }
    }
  }
}

It wasn't working before. I must have missed something. Thanks!

[superandrew213]

When a type error occurs, the other errors are triggered too. Is there a better way to show only type error message other than going through the errors list and looking for type errors?

[epoberezkin]

I don't understand. What's the schema/data and what are the messages? When you say "triggered" what exactly do you mean?

[superandrew213]

If I validate { size: 'abc' } in the above example, it will return both type and minimum error.

[epoberezkin]

It doesn't for me: https://runkit.com/esp/593d4c73c899fe001280d79c

[epoberezkin]

"minimum" etc. is only validated for numbers, it should not generate any errors if the data is not a number.

[superandrew213]

My mistake, it seems that my application is converting strings to NaN.

[superandrew213]

Should it still trigger both type and minimum errors?

[epoberezkin]

for NaN? Yes, because typeof NaN is "number".

[superandrew213]

Yes, but why is it generating a type error?

[epoberezkin]

it doesn't for me: https://runkit.com/esp/593d4c73c899fe001280d79c

See ajv-validator/ajv#182

Thanks for the link to the discussion. I'm testing a lot of different types and the type and minimum error were both generated when "type": "integer" with { size: NaN }.

{
  "type": "object",
  "properties": {
    "size": {
      "type": "integer",
      "minimum": 4,
      "errorMessage": {
        "type": "Size must be an integer",
        "minimum": "Size cannot be less than 4"
      }
    }
  }
}

[epoberezkin]

NaN is not an integer. But minimum applies to it because it is a number.

[superandrew213]

Ok got it. A bit confusing though.
