# Django JSON Schema [](https://travis-ci.org/m19t12/django-json-schema) [](https://coveralls.io/github/m19t12/django-json-schema?branch=master) Django JSON Schema Field. ## Table of content - [Introduction](#introduction) - [Installing](#installing) - [Usage](#usage) - [TODO](#TODO) ## Introduction Django JSON Schema is a library for displaying and validating postgresql jsonb data. ## Installing ``` pip install django_json_schema ``` ## Usage First you create a schema class. Schema class is a django abstract model class (abstract = True). You can import SchemaMeta class or create an abstract class. If you want to validate and display nested data you can do this with the SchemaForeignKey. For example to validating this dict data. ```python { 'name': 'parent', 'age': 50, 'son': { 'name': 'son', 'age': '15', 'school': { 'name': 'school', 'address': 'school address' } } } ``` We create this three schema classes. We can use any django model or third party field. ```python #schemas.py from json_schema.models import SchemaForeignKey, SchemaMeta class SchoolSchema(models.Model): name = models.CharField(max_length=128) address = models.CharField(max_length=128) Meta = SchemaMeta() class SonSchema(models.Model): name = models.CharField(max_length=128) age = models.IntegerField() school = SchemaForeignKey(SchoolSchema, on_delete=models.CASCADE) Meta = SchemaMeta() class ParentSchema(models.Model): name = models.CharField(max_length=128, default="test") age = models.IntegerField() son = SchemaForeignKey(SonSchema, on_delete=models.CASCADE) Meta = SchemaMeta() ``` After we create our model. ```python #models.py from django.db import models from json_schema.fields import JSONSchemaField from .schemas import ParentSchema class JSONSchemaModel(models.Model): simple_text = models.CharField(blank=True, null=True, max_length=256) simple_int = models.IntegerField(blank=True, null=True) parent = JSONSchemaField(schema=ParentSchema, blank=True, schema_array=True) ``` ## TODO Support array elements.
