Overriding sprox admin form edit validator (un requiring a field)

[Alon Nisser]

I'm using  customized sprox tables and (soom) forms in tg admin controller - when I submit a form with some empty fields I get a red " Please enter a value" message besides each empty fields. the problem is - it shouldn't validate those fields, I'm perfectly happy with them empty.  I'm not talking about removing specific fields from the form (which I could easily enough do with __omit_fields__) since the empty fields vary in different scenarios. I just need sprox to "Un require" a specific list of (could) be empty fields.

how can I achieve this? couldn't find it the docs

using tg 2.1.3

thanks for the help

By default sprox reads your __model__ definition add required
instructions from __require_fields__ then removes __omit_fields__ and
that's the validation it uses. So if you are not setting those field
specifically in __require_fields__ then they are being set in the
model layer. Perhaps your SQLAlchemy classes have fields for those as
"Not Null" which Sprox translates into non empty on submit.
