Python Pydantic获取JSON，无论是否验证

Question

我在Pydantic中有一个验证失败的类。无论失败，我都想获取JSON。什么好主意吗?

from pydantic import BaseModel, Field, ValidationError
class Model(BaseModel):
a: float = Field(ge=1.0)
try:
m = Model(a=0.5)
print(m.json())
except ValidationError as e:
data = e.data()  # fake method, would return '{"a": 0.5}
data['errors'] = e.json()
print(data)

Answer 1

您可以手动创建字典，然后将其传递给下一步

from pydantic import BaseModel, Field, ValidationError
class Model(BaseModel):
a: float = Field(ge=1.0)
try:
d = {'a': 0.5}
m = Model.parse_obj(d)
print(m.json())
except ValidationError as e:
d['errors'] = e.json()
print(d)
