How to make validation using onelinevalidation library In Python

#python #webdev #api #tutorial

Hi 🙂🖐

In this post, I will share with you how to use onelinevalidation library In Python.

What is onelinevalidation

onelinevalidation It is a simple library in the Python language that performs validation in an easy and simple way.

install onelinevalidation 

python pip install onelinevalidation
Enter fullscreen mode Exit fullscreen mode

Examples of how to use 

 from onelinevalidation import validate_form userData = {"username": "amr123", "email": "amr.@aol.com", "password": "123Ab#"} print(validate_form(userData))
Enter fullscreen mode Exit fullscreen mode

Result 

{'error': {'username': 'Invalid username should be like this abc_123 or abc. abc', 'email': 'This email address is not valid', 'password': 'The password length must be at least 8 uppercase, lowercase letters, numbers, symbols like @aA123#*'} }
Enter fullscreen mode Exit fullscreen mode

Create custom validate

If you want more control use custom_validate 

from onelinevalidation import custom_validate pattrens = [ "[a-zA-Z]+[_.]+[a-zA-Z0-9]+", "[a-zA-Z0-9_-]+[@](aol|gmail|yahoo|outlook)+(.com)+", "^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{8,}$" ] messages = [ "Invalid username should be like this abc_123 or abc. abc", "This email address is not valid", "The password length must be at least 8 uppercase, lowercase letters, numbers, symbols like @aA123#*" ] print(custom_validate(userData, pattrens, messages))
Enter fullscreen mode Exit fullscreen mode

Result 

{'good': {'username': 'amr_123', 'email': 'amr@aol.com', 'password': '123---Ab#'}}
Enter fullscreen mode Exit fullscreen mode

Do you not prefer dealing with the regex 🙃?

Now in the new version 🥳🎉, you can perform validation using callback functions. From the validators library 

 from onelinevalidation import validate_data_with_callbacks import validators user_data = { 'btc': '00000000000000000000000', 'amount': 0.5, 'md5': '0000' } messages = [ 'Invalid btc address', 'The minimum value must be at least $1.', 'Invalid md5 value' ] from functools import partial callbacks = [ validators.btc_address, {'func': partial(validators.between, min_val = 1, max_val = 100)}, validators.md5 ] result = validate_data_with_callbacks(user_data, callbacks, messages) print(result)
Enter fullscreen mode Exit fullscreen mode

Result 

{'errors': {'btc': 'Invalid btc address', 'amount': 'The minimum value must be at least $1.', 'md5': 'Invalid md5 value'}}
Enter fullscreen mode Exit fullscreen mode 
 from onelinevalidation import validate_data_with_callbacks import validators user_data = { 'btc': '3Cwgr2g7vsi1bXDUkpEnVoRLA9w4FZfC69', 'amount': 1, 'md5': 'd41d8cd98f00b204e9800998ecf8427e' } messages = [ 'Invalid btc address', 'The minimum value must be at least $1.', 'Invalid md5 value' ] from functools import partial callbacks = [ validators.btc_address, {'func': partial(validators.between, min_val = 1, max_val = 100)}, validators.md5 ] result = validate_data_with_callbacks(user_data, callbacks, messages) print(result)
Enter fullscreen mode Exit fullscreen mode

Result 

{'good': {'btc': '3Cwgr2g7vsi1bXDUkpEnVoRLA9w4FZfC69', 'amount': 1, 'md5': 'd41d8cd98f00b204e9800998ecf8427e'}}
Enter fullscreen mode Exit fullscreen mode
