Can't I set the number with a decimal part to "MinMoneyValidator()" and "MaxMoneyValidator()" in "MoneyField()" with Django-money?

Question

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()?

Answer 1

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)),
        ]
    )
