Is it possible to access to a pickle file saved in a directory in Django views?
Let me explain, here is my problem: In order not to get bothered with a database, I saved two machine learning models in .pickle in a folder in my Django project. Then in the corresponding views.py I want to open and use this model. The fact is that all this works well when I run the server locally but once deployed on heroku, impossible to access these models and the site does not work. Do you have an idea, is it possible to use this method once deployed or do I have to save them in a database project files organization : main_folder > models_folder > saved_models_folder > my_model.pickle (here the model that I want to open) app_folder > views.py ( here is the file in wich I try to open the .pickle model) Actually I have this code, but it can't work because I'm not in the models folder when I try to open it. def open_model(file_name): base_dir = 'models_folder\\saved_models_folder' file_path = os.path.join(base_dir, file_name) if os.path.exists(file_path): print("Loading Trained Model") model = pickle.load(open(file_path, "rb")) else: print('No model with this name, check this and retry') model = None return model If someone has a little idea I am greatly interested Thanks. -

Python Django ignore atomic
My question is as follows. Let's say that I have a big logic that is happening (it can fail on multiple places), and it's wrapped with transaction.atomic on the high level. I would love if one part of the logic, could ignore that. I have one piece of code that just moves state of the table (let's say order to make it simple) At the start of operation I move order from waiting to in progress and I have 2 more stats (success and error). If exception happens, I would love to move it to the error state, and if not, to move it to success state. But, because it's all wrapped inside transcation.atomic, after exception, it goes back to waiting rather then error. Any idea how I can ignore atomic operation for one method wrapped inside it? -

How to differentiate new users and existing users on OAuth using Django?
I want my users to be differentiated between : Returning users, and New users while using OAuth such that when I use django-allauth package for OAuth using Google, Github, and LinkedIn, it doesn't create a new user from the login page which is meant only for existing users but rather redirect them to the sign up page. So far I've found that new users just end up making new accounts from the login page as well and I don't want that in the case I'm making it an invite-only app or something similar. -

How to create a loop for a approval system?
I created a approval system for my project. I have several users. These users are analyst, lead, manager, etc. I have a credit limit table (DoaTable) in my system. I want to when a lead type user updates a field in this table it shouldn't be accepted until a manager approves it. So, the old value should be valid until the manager approves the new values, and when the manager approves it the new value should be accepted. I created a new model. When a lead wants to update this table, data will save a second model (table) called as DoaTableBeforeApproval. In this way, when a manager approved the table which a lead update, DoaTable should be equal to new table (DoaTableBeforeApproval).
