How to Avoid Duplicate Validation When Creating Django Model Instances Manually and via Forms?
When I create new instances using forms, I know that calling is_valid on the form automatically runs the full_clean method for validation. After that, I just call save on the form.
But when I create new instances manually, I need to call full_clean manually before calling save.
Accessing ‘self.user’ or ‘self.user_id’ in Django model’s clean() method
I need to know if this is possible in a model’s clean or save method (ideally clean), without using forms, as I want specific validation logic to be directly tied to the model so that both forms and manager commands (e.g., Model.objects.create() in shell or views) are validated equally.

How do I expose information from Django model to the forms/views(?)/html(?) to be able to see all information built-in the model
I am trying to add more information to a form dropdown built using Django forms. A basic explanation of the program is:
Django form saving wrong information to database
So in my form, when I select a time choice, for example “8 PM” it stores in the database as a different time, I’ve checked the form submission and it is being submitted as the correct time, but not being saved as such, is there anything wrong with the code?
