=======================
This is a project that is used to validate fields which is empty or it contain accurate values. Before touching the database we can check and raise appropriate error message if any mistmatch on it, else return True.
1) Check value is missed or empty
2) Check wether the datatype is correct or not
2.1) int = Specifies the integer value
2.2) str = Specifies the string value
2.3) email = Specifies the email value
2.4) phone = Specifies the phone number value
2.5) alpha = Specifies the alphabetes value
2.6) '' = Specifies the null value, is equal to str
2.7) bool = Specifies the boolean value
Installing
=======================
pip install validate-field
Usage
=======================
Enter received_field(values that comes from the front-end side) and required_field(list of values that need to be check in th back-end)
from validate_field.validation import validate_field
received_filed = {
'id':1,
'name':"testuser",
'email':'testmail@gmail.com',
'mobile':'+918330069872',
'password':"testpass@122#",
'is_active':True
}
required_filed = [
['id','int'],
['name','alpha'],
['email','email'],
['mobile','phone'],
['password','str'],
['is_active','bool']
]
validation_result = validate_field(received_filed, required_filed)

Result
====================
>> password is not a string value
If you are does not specify the field type, then the field type will be consider as **string**(str)
Scenario : Specify 'password' field type as " "
received_field = {
