FloatField cant be edited in admin.

[aagaande@…]

When adding the following FloatField to a model:
score = models.FloatField(blank=True,null=True,max_digits=1,decimal_places=1)
And setting it to for example 5.5, in the admin panel it will show as "5.". And if you try to save it it will complain with "Please enter a valid decimal number with a whole part of at most 0 digits."

I've checked the value, and it does store correctly, so the bug is in the admin panel.

You have a bad combination of arguments there; max_digits=1 means "do not accept numbers with more than one total digit in them", which means that decimal_places can't do much for you -- as soon as you enter the "5" you've got one total digit and max_digits won't let you enter any more. If you need to store a number of the form "5.5", you need max_digits=2, decimal_places=1.
