Json-schema bundle

Based on a fork of https://github.com/HadesArchitect/JsonSchemaBundle

Features

Json Schema generation through command (via Doctrine or Php)
Json Schema validation annotation
Json Schema service that accepts class instances

Installation

Composer:

composer require soyuka/jsonschemabundle

Load the bundle:

<?php
// app/AppKernel.php

use Soyuka\JsonSchemaBundle\JsonSchemaBundle;

public function registerBundles()
{
    $bundles = array(
        // ...
        new JsonSchemaBundle(),
    );
}

Json Schema generation

The default is to parse files located in every Entity directory of every Bundle. The default strategy uses php to parse your class (see php-to-json-schema).

app/console jsonschema:generate

If you want to parse another directory, just specify it through the --directory option:

app/console jsonschema:generate -d Model

If you want to use Doctrine annotation to generate a json schema, specify the doctrine strategy. Note that the doctrine/orm-bundle will be needed:

app/console jsonschema:generate --strategy doctrine

Every json schema will be written to the configurable directory of your choice by keeping the following tree architecture:

BundleName/Entity.json

The default value is %kernel.root_dir%/Resources/validators, so assuming the Entity parsed is in AcmeBundle/Entity/Product, the schema will be written in %kernel.root_dir%/Resources/validators/AcmeBundle/Product.json.

Validation annotation

This bundle adds a JsonSchema class annotation. When no option is given, the validator will look in the json path (same architecture than with schema generation).

The most basic example will be:

<?php
use Soyuka\JsonSchemaBundle\Constraints as JsonSchemaAssert;

/**
 * @JsonSchemaAssert\JsonSchema
 */
class DefaultJsonSchema
{
}

See here for the full class.

If you want to use a json schema at a different location, or even remote, specify the path of your choice:

<?php
use Soyuka\JsonSchemaBundle\Constraints as JsonSchemaAssert;

/**
 * @JsonSchemaAssert\JsonSchema(schema = "validators/specific.json")
 */
class SpecificJsonSchema
{
}

The schema option value is retrieved using the JsonSchema\Uri\UriRetriever (any value that works there works in the annotation).

Configuration

json_schema:
    path: 'foobar'
    cache: 'some_psr_cache_service' #cache schema's

Translations

Translation domain is JsonSchemaViolations, therefore default translations would be located in:

%kernel.root_dir%/Resources/translations/JsonSchemaViolations.{lang}.{format}

Every translation will be given following string parameters:

%property%: the property path
%expected%: the expected value
%invalid%: the current invalid value

Keys are the constraint code, for example with minLength:

<source>minLength</source>
<target>%property% is not long enough, expected %expected% got "%invalid%"</target>

Hack

If you want to handle JsonSchema validation yourself, but have issues using Entity instances with justinrainbow/json-schema, you may want to take a look at the PropertyAccessorConstraint. Here, it'll override the ObjectConstraint so that object properties are accessed through the PropertyAccessor. See the Validator class.
