Easy JSON Validator

Description

A python package for deep json validation easy to use and well explained

Install

pip install easy-validator

Usage example

Success Case

from easyvalidator import JsonValidator

source = {"name": "My Name", "birth": "2000-01-01", "salary": 1000} # your json

template = {"name": ["NotNull"]} # what you want to test 

validator = JsonValidator(template=template, source=source)       

result = validator.validate()       

print(f"result: {result}")

# result: {'name': {'value': "My Name", 'rules': ['NotNull'], 'validations': {'NotNull': {'status': 'OK'}}}}

Fail Case

from easyvalidator import JsonValidator

source = {"name": null, "birth": "2000-01-01", "salary": 1000} # your json

template = {"name": ["NotNull"]} # what you want to test

validator = JsonValidator(template=template, source=source)       

result = validator.validate()       

print(f"result: {result}")

# result: {'name': {'value': "My Name", 'rules': ['NotNull'], 'validations': {'NotNull': {'status': 'FAIL', 'msg': 'Field can not be null'}}}}

More Complex Case with deep field validation

from easyvalidator import JsonValidator

source = {"name": "My Name", "birth": "2000-01-01", "salary": 1000, "address": {"details": "number": 13}} # your json

template = {"address": {"details": "number": ["GreaterThan(value=12)", "IsBetween(start=10, end=20)"]}} # what you want to test 

validator = JsonValidator(template=template, source=source)       

result = validator.validate()       

print(f"result: {result}")

# result: {"address": {"details": "number": {'value': 13, 'rules': ['GreaterThan(value=12)', 'IsBetween(start=10, end=20)'], 'validations': {'GreaterThan(value=12)': {'status': 'OK'}, IsBetween(start=10, end=20)': {'status': 'OK'}}}}
