 Peewee requires that you be explicit w/the decimal field. If you dislike this functionality, then you can subclass it and override the `get_modifiers()` method.

```python

class NumericField(DecimalField):
    def get_modifiers(self):
           pass
```
Why can not you specify max_digits, etc. In ordinary PhpPgadmin, this can be done and the column is simply called numeric without max_digits, etc.
