custom attributes of model field

Hello,

Is there a way in Django to add custom attributes to a model fields
(without resorting to subclassing fields)?

I would like to only display certain fields in certain sections of my
template. (Eventually, each type of field will be displayed in a
separate tab.) I thought about adding a custom attribute to each field
to identify which section it should go in. But, so far, I've had no luck.

I have a few field types:

<snip>
class Enum(set):
def __getattr__(self, name):
if name in self:
return name
raise AttributeError

FieldTypes = Enum(["one","two","three",])
</snip>

And a few models:

<snip>
class Model1(models.Model):
a = models.CharField()
b = models.ForeignKey('Model2')
c = models.IntegerField()
a.type = FieldTypes.one # this obviously doesn't work
b.type = FieldTypes.two # this obviously doesn't work
c.type = FieldTypes.three # this obviously doesn't work

class Model2(models.Model):
d = models.CharField()
</snip>

And a form:

<snip>
class Form1(forms.ModelForm):
class Meta:
model = Mode1
</snip>

And a template:

<snip>
{% for fieldType in FieldTypes %}
<div class="{{fieldType}}">
{% for field in form %}
{% if field.type = fieldType %}
{{ field }}
{% endif %}
{% endfor %}
</div>
{% endfor %}
</snip>

But this doesn't work.

Ideas? Or another suggestion for only placing certain fields in certain
sections of the page?

Thanks.
