OK, this is going to be a tough one. Strap down, even if it pisses you off at first - I wouldn’t be writing it if I didn’t think it was helpful.
A programmer has something he wants to build.
He finds a framework.
It looks easy enough to get into. There’s a few tutorials available, which show step by step how to build a basic application of just the right type.
He’s happy. He feels really productive. CRUD just “drops out” of the framework’s design. It’s like it was created with his problem in mind.
Then he’s done with the tutorials. He starts plugging in his own, specific requirements. Every so often he hits a snag, but that’s OK, he can just twist the framework’s arm a bit, right?
It all goes well for a while. Then he hits a big one. The framework doesn’t do quite work the way he wants it to.
