I am trying to add initial data from 1 form into the second form but I cannot seem to get it work.

I want to create a details page with two models for an auction site with django but keep getting FieldError. How do I correct this error?
I am creating an ebay like aunction site, the details view page should reflect details from two models. One of the models has the details of the current_bid (this is created when creating the listing), there is also the second model that contains new_bids (this is where the users who want to purchase the item can input their bids).

Is there a way to mock the firebase_admin credentials.Cerificate class in Django?
In my project, FirebaseAuthentication is used and while running the test cases(pipenv run python manage.py test) I am getting the following error - ValueError: Invalid certificate argument: "None". Certificate argument must be a file path, or a dict containing the parsed file contents. authentication.py from firebase_admin import auth from firebase_admin import credentials cred = credentials.Certificate(os.getenv('FIREBASE_ADMIN_KEY_PATH')) default_app = firebase_admin.initialize_app(cred) tests.py(where I have not imported authentication file) from django.test import TestCase class A(TestCase): .... I am trying to run specific app test case but somehow it is trying to import authentication.py. That is why cred = credentials.Certificate(os.getenv('FIREBASE_ADMIN_KEY_PATH')) is getting executed. I have identified that cred and default_app are declared at global level. And I cannot move it to other function or classes for the same file. I have noticed that cred = credentials.Certificate(os.getenv('FIREBASE_ADMIN_KEY_PATH')) returns the object and not specific data and also calls the Firebase API for authentication. How can I mock this two line at a global level? -

Including custom Python module with heroku app?
I've included my python module in my app as follows -myapp -mymodule -__init__.py -setup.py -migrations -template -etc... and to the requirements.txt file. During build, the module is installed along with everything else in requirements, which I believe puts mymodule in brython_stdlib.js, because I am also using brython. The logs confirm the module is installed, but not where. Successfully built mymodule However, when I go to import the module, I get an error. According the the logs I can see that the client is making ajax calls looking for the file. Not Found: /mymodule.py Not Found: /mymodule/__init__.py Not Found: /static/django_brython/js/Lib/site-packages/mymodule.py ... and so on. (I've edited out a lot of lines here, but you get the idea!) So what I think is happening is that the client is not finding the module, and is asking for it from the server. But I can put a mymodule.py in my app and it still does not find it. Of course I would rather not serve ajax calls for this since it should already be installed along with everything else in the requirements file. Please help! I feel really close to getting this to work, but also now it's been feeling that way for … -

Problem Generating Azure ADLS Gen2 SAS Token for Container with Python?
From azure.storage.blob I'm using the function generate_container_sas. I'm trying to generate a SAS token for a container in an ADLS Gen2 storage account in Azure. I can go into azure portal and generate a working SAS token using an account key with no issues. The token works just fine. However, when I do what I think is the same thing in python I get a token back but when I load it into storage explorer it says "Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.". I have validated all the inputs appear to be correct. The token that is generated looks like: https://<STORAGE_ACCOUNT>.blob.core.windows.net/<CONTAINER_NAME>?se=2022-02-19T05%3A41%3A26Z&sp=rwdlac&sv=2020-10-02&sr=c&sig=jCd8AAatl5o9QsbMHtlca6oNnnRdKqtcOnWN3sZa1c8%3D sas_token = generate_container_sas( account_name=account_name, container_name=container_name, account_key=account_key, permission=AccountSasPermissions(read=True, list=True, write=True, delete=True, create=True, add=True), expiry=datetime.utcnow() + timedelta(hours=expiry_hours) ) -
