kohi's Issues

[REQUEST] - add custom error message

A custom error message is best when I'm returning from an API or when I want translated messages

[REQUEST] - EnumSchema validator

Is your feature request related to a problem? Please describe.
A scheme for validating enums
Kohi doesn't have an easy way for when I need to validate if the value is in a list of possible options like enum.Enum

Describe the solution you'd like

e = EnumSchema().one_of([1, 2, 3])
print(e.validate(1)) # True

e = EnumSchema().not_one_of([1, 2, 3])
print(e.validate(1)) # False

[REQUEST] - add a customizable label to schemas for more accurate error message

Is your feature request related to a problem? Please describe.
It's often so confusing, even if I have multiple uses of a schema, they always throw the same error and I don't know which one it's coming from.

[REQUEST] - methods to validate non positive and non negative numbers

Is your feature request related to a problem? Please describe.
Methods to validate non-positive and non-negative numbers to make the process more concise and standardized

Describe the solution you'd like

from kohi import NumberSchema

NumberSchema().nonnegative().validate(-1) # False
NumberSchema().nonnegative().validate(0) # True
NumberSchema().nonnegative().throw().validate(-1) # ValidationError: number must be greater than or equal to 0

NumberSchema().nonpositive().validate(1) # False
NumberSchema().nonpositive().validate(0) # True
NumberSchema().nonpositive().throw().validate(1) # ValidationError: number must be less than or equal to 0

[REQUEST] - a validator for dicts like DictSchema

Is your feature request related to a problem? Please describe.
Currently there is no way to validate complex data as a dict, and this is a downside

Describe the solution you'd like

d = DictSchema().props(
    name=StringSchema().min(3),
    age=NumberSchema().min(18)
).label('user_data')
