Your `max_digits`

should be greater than the `decimal_places`

Note that `0.1000000000`

uses 10 digits, but `1.0000000000`

uses 11 digits. Therefore if you have `max_digits=10`

and `decimal_places=10`

, then any numbers greater or equal to `1.0`

will give errors.

If you don’t need so decimal places, maybe you need something like `max_digits=10`

, `decimal_places=3`

. Or if you really need `decimal_places=10`

, then maybe you need something like `max_digits=12`

, which would support values less that 1000.

Django 1.9 has added a validator to try to prevent errors like this. See ticket 24636 for more details.

Argument `max_digits`

must be greater then `decimal_places`

.

e.g

```
aaf_1kg_all = models.DecimalField(max_digits=5, decimal_places=2, blank=True, null=True)
```

DECIMAL columns do not permit values larger than the range implied by the column definition. For example, a DECIMAL(3,0) column supports a range of -999 to 999. A DECIMAL(M, D) column permits up to M – D digits to the left of the decimal point.

If you want to accept 10 digits in both number and decimal positions you need to declare ‘aaf_1kg_all’ like this

decimal_places=10)

```
aaf_1kg_all = models.DecimalField(blank=True, null=True, max_digits=20, decimal_places=10)
```
