Odoo (OpenERP) custom field error - customization

I've added a custom field to the Invoice model called x_contract_currency_rate which is a float field. I've added the field into the view and it's working OK on existing invoices.
If I try to add a new invoice it throws me the error below and the invoice form will not load. As far as I can tell it's got something to do with the field's default value, but I have not set a default nor do I see an option to do so.

You are probably doing something like:
default=<id>
where you should actually be doing:
default=<record>
when declaring a new field.

django - overriding save method with super returns unique contraint error when creating object

Overriding save method with super returns unique contraint error when creating object. How to solve it?
Adding context to the code. I need to create an object1 and I need to assign some value dependent on a related foreign object. I need to assign the value after creating an instance of object1, otherwise an error pops up that the object does not exist and there is no relationship.
def save(self, *args, **kwargs):
if self.pk is None:
super(IntoDocumentProduct, self).save(*args, **kwargs)
# some logic
# more logic
super(IntoDocumentProduct, self).save(*args, **kwargs)
self.full_clean()
I am also posting the error that shows up when I test the api in insomnia.
IntegrityError at /api/wms/intodocuments/products/create/
duplicate key value violates unique constraint "wms_dokumentprzyjeciaprodukt_pkey"
DETAIL: Key (id)=(151) already exists.
Below is the error that appears in the console. It directs specifically to the save() method in the model. I don't know what is wrong with it. After all, I can't use self.save(), because there will be a recursive loop.

I'm like 90% sure you have to define your super properly. I tried what you have and didn't get a compile error, but it's definitely not best practices. Particularly, if you're not defining a return within your if statement. That would cause super to be called twice which could be throwing the exception due to the save function running twice. I typically set it right after my function declaration (my prefered method) or as my last line.
def save(self, *args, **kwargs):
super(IntoDocumentProduct, self).save(*args, **kwargs)
# your overwrite code
or
def save(self, *args, **kwargs):
# your overwrite code
super(IntoDocumentProduct, self).save(*args, **kwargs)

django celery asynchronous file saves to storage

So I want to asynchronously conduct file saves to django file storage. I've tried to achieve this by overwriting the default File System Storage class.
import hashlib
import os
import uuid
import django.core.files.storage as storage
from celery import shared_task
from django.core.files import File
class DefaultStorage(storage.FileSystemStorage):
def __init__(self):
super(DefaultStorage, self).__init__()
#shared_task
def _save(self, name, content):
# need to encrypt file before saving
return super(DefaultStorage, self)._save(name, content)
#shared_task
def _open(self, name, mode='rb'):
# need to decrypt before opening
return File(open(self.path(name), mode))
def get_available_name(self, name, max_length=None):
# we return a hash of the file given,
# in case we miss out on uniqueness, django calls
# the get_alternative_name method
dir_name, file_name = os.path.split(name)
file_root, file_ext = os.path.splitext(file_name)
file_root = hashlib.md5(file_root.encode()).hexdigest()
name = os.path.join(dir_name, file_root + file_ext)
return super(DefaultStorage, self).get_available_name(name, max_length)
def get_alternative_name(self, file_root, file_ext):
# we insert a random uuid hex string into the given
# file name before returning the same back
return '%s%s%s' % (file_root, uuid.uuid4().hex, file_ext)
def save(self, name, content, max_length=None):
# override existing system storage save method
# to ensure that we call the shared task and
# utilize the distributed task queue celery offers
has_chunks = hasattr(content, 'chunks')
name = content.name if not name else name
content = File(content, name) if not has_chunks else content
name = self.get_available_name(name, max_length=max_length)
saved = self._save.delay(self, name, content)
return saved
def open(self, name, mode='rb'):
# override existing system storage open method
# to ensure that we call the shared task and
# utilize the distributed task queue celery offers
return self._open.delay(name, mode)
The idea is to override the existing save method to fire off the shared_task named _save. However, I am facing the following error while trying to do the same.

kombu.exceptions.EncodeError: Object of type 'DefaultStorage' is not JSON serializable
I believe I have found the source of the issue. It is because we cannot pass "file" objects as parameters to shared_task functions. If this is the case, then how can I send my file to the _save function?
Before sending, the file isn't saved yet. We need to save the file only after receiving.

Django ViewFlow: Navigate Step based on Validation

I am using the HelloWorld example located at the ViewFlow cookbook.
The whole source code is same as the helloworld project with the only change being:
flows.py
check_approve = (
flow.If(lambda activation: activation.process.approved)
.Then(this.send)
.Else(this.start) # Edited (was this.end)
)
So basically I intend that if user keeps the Approved checkbox as un-selected and proceeds then it will push the task back to the start step.
I get this error when I run it:
NotImplementedError at /workflow/helloworld/helloworld/3/approve/11/
No exception message supplied

I am getting this error when i am trying to save the RequisitionImage object record both from the admin model and from my view.
So how to avoid this error and what is causing it ?
