Hi Siddharth,

If I understand correctly your solution, it will overwrite the field size definition but what I'm trying to do it's to avoid the user to enter strings longer than the maxlenght defined, in the frontend.

Also I want to understand why I cannot define a valid html attribute from a view.

P.S. thanks for your answer.

Hi Siddhartd,

at the end I've programmed a Python constrain to solve the problem:

@api.constrains('name')
def _check_description(self):
for description in self:
if len(description.name) > 100:
raise ValidationError("El campo descripción debe tener 100 caracteres como máximo.")

Thanks for your help.
