I have a need to add listeners to models who inherit from a mixin, and I want the mixin to have abstract methods that the overriding classes must implement to follow the mixin spec, like so: from abc import ABC, abstractmethod from app import db from sqlalchemy.orm import declarative_mixin @declarative_mixin class FooMixin(ABC): @abstractmethod def must_implement(self): ..

As I was writing repetitive test code, I search for some options and found that I could use RequestFactory with a mixin. But what I’m not understanding is why the test is not failing for a non existing ..
I’ve learned that you can emulate a mixin/inheritance by simply writing a function that decorates a class: def dec(cls): def foo(self): return self.f cls.foo = foo return cls @dec class Hello: def __init__(self, f, b): self.f = f h = Hello(10, 20) assert h.foo() == 10 This is similar to using a mixin/general inheritance: class ..
Currently I am writing a Python program with a plugin system. To develop a new plugin a new class must be created and inherit from a base plugin class. Now it should be possible to add optional functions via mixins. Some mixins provide new functions others access builtin types of the base class and can ..
I am currently building a system that will aggregate posts across multiple sources. These sources have very few properties in common — for example, the only thing in common across all the sources is that a post contains text: class Post: def __init__(self, text=None): self.text = text def persist(self): row_id = FoobarDB.insert(‘post’, text=self.text).row_id id = ..
