英文:
Can't I set the number with a decimal part to "MinMoneyValidator()" and "MaxMoneyValidator()" in "MoneyField()" with Django-money?
问题
我使用Django-money，然后在MoneyField()中将0.00和999.99分别设置为MinMoneyValidator()和MaxMoneyValidator()，如下所示：
# "models.py"
from django.db import models
from djmoney.models.fields import MoneyField
from djmoney.models.validators import MinMoneyValidator, MaxMoneyValidator
class Product(models.Model):
name = models.CharField(max_length=50)
price = MoneyField( # 这里
max_digits=5, decimal_places=2, default=0, default_currency='USD',
validators=[ # 这里 # 这里
MinMoneyValidator(0.00), MaxMoneyValidator(999.99),
]
)
然后，我尝试添加一个产品，如下所示：
但是，我收到以下错误：
TypeError: 'float'对象不可订阅
因此，我将0和999分别设置为MinMoneyValidator()和MaxMoneyValidator()，如下所示，然后上面的错误得到解决：
# "models.py"
from django.db import models
from djmoney.models.fields import MoneyField
from djmoney.models.validators import MinMoneyValidator, MaxMoneyValidator
class Product(models.Model):
name = models.CharField(max_length=50)
price = MoneyField(
max_digits=5, decimal_places=2, default=0, default_currency='USD',
validators=[ # 这里 # 这里
MinMoneyValidator(0), MaxMoneyValidator(999),
]
)
实际上，我可以在models.DecimalField()中将0.00和999.99分别设置为MinValueValidator()和MaxValueValidator()，而不会出现任何错误，如下所示：
# "models.py"
from django.db import models
from django.core.validators import MinValueValidator, MaxValueValidator
class Product(models.Model):
name = models.CharField(max_length=50)
price = models.DecimalField( # 这里
max_digits=5, decimal_places=2, default=0,
validators=[ # 这里 # 这里
MinValueValidator(0.00), MaxValueValidator(999.99)
],
)
那么，在MoneyField()中不能设置带小数部分的数字到MinMoneyValidator()和MaxMoneyValidator()吗？
英文:
I use Django-money, then I set 0.00 and 999.99 to MinMoneyValidator() and MaxMoneyValidator() respectively in MoneyField() as shown below:
# "models.py"
from django.db import models
from djmoney.models.fields import MoneyField
from djmoney.models.validators import MinMoneyValidator, MaxMoneyValidator
class Product(models.Model):
name = models.CharField(max_length=50)
price = MoneyField( # Here
max_digits=5, decimal_places=2, default=0, default_currency='USD',
validators=[ # Here # Here
MinMoneyValidator(0.00), MaxMoneyValidator(999.99),
]
)
Then, I tried to add a product as shown below:
But, I got the error below:
> TypeError: 'float' object is not subscriptable
So, I set 0 and 999 to MinMoneyValidator() and MaxMoneyValidator() respectively in MoneyField() as shown below, then the error above was solved:
# "models.py"
from django.db import models
from djmoney.models.fields import MoneyField
from djmoney.models.validators import MinMoneyValidator, MaxMoneyValidator
class Product(models.Model):
name = models.CharField(max_length=50)
price = MoneyField(
max_digits=5, decimal_places=2, default=0, default_currency='USD',
validators=[ # Here # Here
MinMoneyValidator(0), MaxMoneyValidator(999),
]
)
Actually, I can set 0.00 and 999.99 to MinValueValidator() and MaxValueValidator() respectively in models.DecimalField() without any errors as shown below:
# "models.py"
from django.db import models
from django.core.validators import MinValueValidator, MaxValueValidator
class Product(models.Model):
name = models.CharField(max_length=50)
price = models.DecimalField( # Here
max_digits=5, decimal_places=2, default=0,
validators=[ # Here # Here
MinValueValidator(0.00), MaxValueValidator(999.99)
],
)
So, can't I set the number with the decimal part to MinMoneyValidator() and MaxMoneyValidator() in MoneyField()?

For this, you can use Decimal():
from decimal import Decimal
class Product(models.Model):
# ...
price = MoneyField(
max_digits=5, decimal_places=2, default=0, default_currency='USD',
validators=[ # Here # Here
MinMoneyValidator(Decimal(0.00)), MaxMoneyValidator(Decimal(999.99)),
]
)
