We use django admin as a client-facing backend, so we need to make it user
friendly. I have a model with a bunch of DecimalFields representing
nutritional data.
The fields all look like this:
{{{ g_carbs = DecimalField(max_digits=13, decimal_places = 8, null=True,
blank=True) }}}
If the field is left blank, or if a non-zero value is provided, the admin
form looks and works great. For example, for a non-blank, non-zero value
like 10.5, it displays something like 10.50000000, which is fine.
The problem is that for any 0 values, the form field displays 0E-8 which,
although technically correct, is not going to cut it for clients, who are
not scientists or engineers for the most part and are unfamiliar with E
notation. We're using DecimalFields rather than FloatFields to avoid this
type of notation.
I am not using a custom ModelForm or any custom admin tricks. Its just
what gets auto-rendered by django admin for that model.
