Anytime I add a new compute field to my code I'm getting a strange 404 error. The module I'm writing already has compute fields and these still work, but any new ones send up the error. I'm using Odoo 8.

Here's an example of a situation that throws up the error:

 date_test = fields.Date(compute='get_date')

@api.one

def get_date(self):

self.date_test = fields.Date.context_today

 and this:

model_id = fields.Integer(compute="get_model_id")

@api.one

def get_model_id(self):

     self.model_id = self.env.ref('my_module.xml_id').id

Here's the traceback for the first example:

I'm pretty lost on this one. Any help would be appreciated.
