7 months ago Hi @xxxxxxbox This is because you were following the documentation for BlackSheep v1 (stable at that time), installing BlackSheep v2 (alpha release at that time).
I am the only maintainer of the framework and unfortunately had no time to keep the documentation for the alpha version up to date while working on it.
Now the documentation is up to date:
- https://www.neoteroi.dev/blacksheep/ - for v2, not stable
- https://www.neoteroi.dev/blacksheep/v1/ - for v1
I continue following tutorial. But get new errors when trying to reproduce code from next steps of tutorial.
As I understand Dependency Injection is one of key features of BlackSheep. As DI is a new approach for me, I read several times the article dedicated to it. https://www.neoteroi.dev/blacksheep/dependency-injection/ I got the idea but can't say that I understand DI fully for now... When I Copy/Paste example code and run it I get AttributeError: 'Container' object has no attribute 'add_exact_transient' My IDE also display warning "unresolved attribute for several method' Please see enclosed screenshot.
app.services.add_exact_transient(A) app.services.add_exact_scoped(B) app.services.add_exact_singleton(C)
DI tutorial page is not the only page of documentation where add_exact_scoped method is used in examples.
As the official documentation is almost the only source of information about BlackSheep It's hard for new users of BS to find right way of using it. As one of new users I appreciate if you update key parts of tutorial when you have some free time. Thanx.
I used Blacksheep v2.08a
