# Về các phiên bản của FastAPI

**FastAPI** đã được sử dụng ở quy mô thực tế (production) trong nhiều ứng dụng và hệ thống. Và phạm vi kiểm thử được giữ ở mức 100%. Nhưng việc phát triển của nó vẫn đang diễn ra nhanh chóng.

Các tính năng mới được bổ sung thường xuyên, lỗi được sửa định kỳ, và mã nguồn vẫn đang được cải thiện liên tục

        How has this issue affected you? What are you trying to accomplish?

You could create an API with a *path operation* that could trigger a request to an *external API* created by someone else (probably the same developer that would be *using* your API).

The process that happens when your API app calls the *external API* is named a "callback". Because the software that the external developer wrote sends a request to your API and then your API *calls back*, sending a request to an *external API* (that was probably created by the same developer).

        a full-time Guava team member. [Feedback](https://stackoverflow.com/a/4543114) from our
        users indicates that they really appreciate Guava's high power-to-weight ratio. It's
        important to us to keep Guava as easy to use and understand as we can. That means boiling
        features down to compact but powerful abstractions, and controlling feature bloat carefully.

  - type: textarea
    attributes:

Let's imagine that we want to have a dependency that checks if the query parameter `q` contains some fixed content.

But we want to be able to parameterize that fixed content.

## A "callable" instance { #a-callable-instance }

In Python there's a way to make an instance of a class a "callable".

Not the class itself (which is already a callable), but an instance of that class.

The last `CommonQueryParams`, in:

```Python
... Depends(CommonQueryParams)
```

...is what **FastAPI** will actually use to know what is the dependency.

It is from this one that FastAPI will extract the declared parameters and that is what FastAPI will actually call.

In this case, the first `CommonQueryParams`, in:
