Hi,
You don't need to keep the same field in the dependency list, just remove the x_studio_test field from dependency list and see if it makes any diff.

Thanks

Hi 
Yoo can try this it will fill the field by default and you can change it after as you want :

@api.model

def default_get(self, fields):

res = super(YourModule, self).default_get(fields)

if 'x_studio_test' in fields and not res.get('x_studio_test'):

     res['x_studio_test'] = 234

 return res

Hi,

You can try this code,
Once you return the value in dictionary format you can fetch the record like record['filed_name']
or you try with the normal method and only need to use record.field_nameie:

for record in self:
        record.x_studio_test = 234

If the record does not return the value like dictionary you can follow the above code.

Another solution is you do not use the studio, and if you make it as a default value, tryfied_name  = fields.Float(string='Field name' , default=234)

Hope it helps
