I want validate a field with one value greater or equal 01/01/1900 in type datetime in Cerberus, but not works this way:
from cerberus import Validator
from datetime import datetime
v = Validator()
schema = {
"birthdate": {
"type": "datetime",
"required": True,
"min": datetime(1900, 1, 1)
}
}
document_valid = {'birthdate': '05/03/1900'}
document_invalid = {'birthdate': '05/03/1800'}
print(v.validate(document_valid, schema)) # I want this True
print(v.validate(document_invalid, schema)) # I want this False
Anyone could help me?
I'm using this version to Cerberus: Cerberus==1.3.4

Your approach is not false, just missing a decisive compoenent - which is to account for the date-format.
try this:
from cerberus import Validator
from datetime import datetime
v = Validator()
to_date = lambda s: datetime.strptime(s, '%d/%m/%Y') # date-formatting
schema = {
"birthdate": {
"type": "datetime",
"required": True,
'coerce': to_date,
"min": datetime(1900, 1, 1)
}
}
document_valid = {'birthdate': '05/03/1900'}
document_invalid = {'birthdate': '05/03/1800'}
print(v.validate(document_valid, schema)) # I want this True
print(v.validate(document_invalid, schema)) # I want this False
