Loader callback does not find the schema-references

[cumafo]

Is there a plan for handling this?

[pboettch]

Can you give an simple example - but complete?

That would require a proper implementation of json_uri. Which today is a little bit simplistic.

[cumafo]

Thanks for quick reply. Here are schemas and a couple of json documents. Working with valijson. /C jex.tar.gz root schema is digital-receipt-schema.json

[pboettch]

I very quickly grepped for $ref in your schemas, which ones are the plain-name-fragment?

[pboettch]

Actually it seems to work fine with this library here what I did:

$ <unzip your archive>
$ <adapt the paths to make the json-schema-validate's loader find the schemas
$ path/to/json-schema-validate schema/jsonschema/digital-receipt-schema.json < json-receipts/min-sale-receipt-cash-payment.json 
loading http://api.findity.com/schema/jsonschema/business-definitions.json # 
loading http://api.findity.com/schema/jsonschema/customer-definitions.json # 
loading http://api.findity.com/schema/jsonschema/item-definitions.json # 
loading http://api.findity.com/schema/jsonschema/monetary-definitions.json # 
loading http://api.findity.com/schema/jsonschema/sales-recording-system-definitions.json # 
loading http://api.findity.com/schema/jsonschema/tender-definitions.json # 
loading http://api.findity.com/schema/jsonschema/service-common-definitions.json # 
loading http://api.findity.com/schema/jsonschema/taxi-definitions.json # 
document is valid

Could you give the error-message you are encountering?

[pboettch]

I tried all the instance you're provided, they are all valid. Tweaking them a little bit, I get validation errors.

[cumafo]

Probably something I do not understand here. What do you mean by <adapt the paths to make the json-schema-validate's loader find the schemas?

[pboettch]

In your archive the schemas are located in schemas-json/.

The root-schema has an $id which is: http://api.findity.com/schema/jsonschema/digital-receipt-schema.

The loader-callback (which you have to provide when using this library) of the json-schema-validate-program is called with the complete json-uri of the schema (and referenced schemas).

So it gets called with http://api.findity.com/schema/jsonschema/business-definitions.json for business-definitions.json.

The loader-callback of json-schema-validate is taking the path of the uri and tries to load the file. If it doesn't exists, it bails out.

So, I put all of your schemas to schema/jsonschema/ for the loader-callback to find it. And then it started working.

HTH.

[cumafo]

well, it's the loader-callback that I'm not aware of (and was looking for). Could you point me to how I define/implement that?

[pboettch]

Where did you look?

[cumafo]

while trying it out, in the code mainly. I never tried json-schema-validate. Now looking into that code and found it. Sorry about bothering you. Thanks /C

[pboettch]

Happy to have helped.

One question.....: what version of your software and nlohmann did you use verifying my json? Trying your "master" and nlohmann 3.5.0 I get "no validation has succeeded but ANYOF/ONEOF them is required to validate" on different objects depending on which of the json-files I check. /C
