Expose Django JSONField data as virtual model fields
Use ModelForm and ModelAdmin as usual. Perform simple queries. Migrate to real table columns when needed without code change.
Suitable to store dumb business data, quick prototypes without DB migrations, and replace multi-table inheritance joins.
Use with caution! Replacing relational structures with JSON data should be mindfull architecture decision.
Works with any JSONField django.contrib.postgres, django-annoying, django-mysql, upcoming django Cross-db JSONField
Work in progress part of https://json-schema.org definitions are only supported.
Quick start
import jsonstore
from django import forms
from django.contrib import admin
from django.db import models
from .??. import JSONField
class Employee(models.Model):
data = JSONField(default={})
full_name = jsonstore.CharField(max_length=250)
hire_date = jsonstore.DateField()
salary = jsonstore.DecimalField(max_digits=10, decimal_places=2)
class EmployeeForm(forms.ModelForm):
class Meta:
model = Employee
fields = ['full_name', 'hire_date', 'salary']
@admin.register(Employee)
class EmployeeAdmin(admin.ModelAdmin):
list_display = ['full_name', 'hire_date']
fields = ['full_name', ('hire_date', 'salary')]Demo
The demo shows how to handle multiple User types within single table with JSONField and Django-Polymodels proxies.
