Bug de d�s�rialisation Marshmallow Nested fields
Bonjour,
Je pensais avoir compris le fonctionnement mais la je s�che.
Voici un code tut simple qui retourne des classes diff�rentes pour une structure identique !
Code:
1
2
3
4
5
6
7
8
9
10
11
12

class Class_test_struct1():
def __init__(self, attr1): self.attr1=attr1
class Class_test_struct1Schema(Schema):
attr1=fields.String()
class Class_test_struct2():
def __init__(self, attr2): self.attr2=attr2
class Class_test_struct2Schema(Schema):
attr2=fields.String()
class Class_test():
def __init__(self, struct1, struct2):
self.struct1=struct1,
self.struct2=struct2
class Class_testSchema(Schema):
struct1=fields.Nested(Class_test_struct1Schema)
struct2=fields.Nested(Class_test_struct2Schema)
@post_load
def make_Class_test(self, data, **kwargs):
return Class_test(**data)
inputJson={
"struct1": { "attr1": "where is" },
"struct2": { "attr2": "the bug?" }
}
schema = Class_testSchema()
result = schema.load(inputJson)
print("Returned class: %s" % type(result))
print("type(result.struct1) = %s" % type(result.struct1))
print(result.struct1)
print("type(result.struct2) = %s" % type(result.struct2))
print(result.struct2) |
R�sultat de l'ex�cution :
Code:

| Returned class: <class '__main__.Class_test'>
type(result.struct1) = <class 'tuple'>
({'attr1': 'where is'},)
type(result.struct2) = <class 'dict'>
{'attr2': 'the bug?'} |
Pourquoi un tuple ??
