proposal Meta.exclude in Form

[Constantine]

FormModel have exclude attribute in Meta, but simple Form doesnt:
example usage:

i need base form for editing with many fields, and derived form for
object creation with subset of fields and so i want to exclude
unnecessary fields

[Constantine]

generally it's lack of Meta subclass in simple form, in which we can
configure fields order, exclusion of some fields etc. Now i should
override __init__ method, its not so declarative way as in modelform

Actually, I don't understand.
If you need object creation, ModelForm is the way to go.
You could also take it the other way. Base form should be the one with the smallest field set.

unfortunately ModelForm is not suitable

You are right, base form has the smallest set.
But inheritors' field sets highly intersects and i'cant distinguish
minimum set for base class

Anyway, what's the reason for not implementing Meta in Forms

I doubt Django devs will include Meta.exclude in Form without a fully described use case.
The general idea is don't include feature unless there's no other way.
In your case, I can't see why you can't use a base form and extend it.

PS:
I'm not a Django core dev.
I just noticed this is on django dev mailing list so don't take my words as official core team answer.

i've workaround this overloading init, so the other way exist.
But i surprised when not found meta class in simple form (model and
modelform have)
