!ignoredSubprojects.contains(it.name)
        }.forEach {
            val dir = File("..", it.path)
            assertEquals(it.unitTests, File(dir, "src/test").isDirectory, "${it.name}'s unitTests is wrong!")
            assertEquals(it.functionalTests, File(dir, "src/integTest").isDirectory, "${it.name}'s functionalTests is wrong!")

    That's because it is using the same name as in the OpenAPI spec. So that if you need to investigate more about any of these security schemes you can just copy and paste it to find more information about it.

The `oauth2_scheme` variable is an instance of `OAuth2PasswordBearer`, but it is also a "callable".

It could be called as:

```Python
oauth2_scheme(some, parameters)
```

!!! tip
    ...Although if the whole application is just **crashing immediately** it probably doesn't make sense to keep restarting it forever. But in those cases, you will probably notice it during development, or at least right after deployment.

    So let's focus on the main cases, where it could crash entirely in some particular cases **in the future**, and it still makes sense to restart it.

            .asSequence()
            .filter { nameFilter(it.name) }
            .mapNotNull { it.toKtSymbol(analysisContext) as? KtCallableSymbol }
    }

    override fun getCallableSymbols(names: Collection<Name>): Sequence<KtCallableSymbol> = withValidityAssertion {
        if (names.isEmpty()) return emptySequence()
        val namesSet = names.toSet()
        return getCallableSymbols { it in namesSet }
    }

        val resolvedCall = call.getResolvedCall(bindingContext) ?: return null
        val typeProjection = call.typeArguments.find { it.typeReference == ktTypeReference } ?: return null
        val index = call.typeArguments.indexOf(typeProjection)
        val paramDescriptor = resolvedCall.candidateDescriptor.typeParameters.find { it.index == index } ?: return null
        return resolvedCall.typeArguments[paramDescriptor]
    }

Next, the browser would verify that the response is valid and encrypted with the right cryptographic key, etc. It would then **decrypt the response** and process it.

# WebSockets

When defining WebSockets, you normally declare a parameter of type `WebSocket` and with it you can read data from the client and send data to it.

It is provided directly by Starlette, but you can import it from `fastapi`:

```python
from fastapi import WebSocket
```

!!! tip

    ```

* The `app` directory contains everything. And it has an empty file `app/__init__.py`, so it is a "Python package" (a collection of "Python modules"): `app`.
* It contains an `app/main.py` file. As it is inside a Python package (a directory with a file `__init__.py`), it is a "module" of that package: `app.main`.
* There's also an `app/dependencies.py` file, just like `app/main.py`, it is a "module": `app.dependencies`.

```

We will use this model in our *path operation function*, so, we don't include in it the `hashed_password`.

### `UserInDB` model

Now, let's create a `UserInDB` model.

This will have the data that is actually stored in the database.

We don't create it as a subclass of Pydantic's `BaseModel` but as a subclass of our own `User`, because it will have all the attributes in `User` plus a couple more:

```Python hl_lines="31-33"

                scope.processFunctionsByName(selectedName) { add(it.fir.buildSymbol(builder)) }
                scope.processPropertiesByName(selectedName) { add(it.fir.buildSymbol(builder)) }
            }
            scope.processClassifiersByName(selectedName) { addIfNotNull(it.fir.buildSymbol(builder)) }
            builder.createPackageSymbolIfOneExists(selectedFqName)?.let(::add)
        }
