## Return the same input data { #return-the-same-input-data }

Here we are declaring a `UserIn` model, it will contain a plaintext password:

## Number validations: greater than or equal { #number-validations-greater-than-or-equal }

With `Query` and `Path` (and others you'll see later) you can declare number constraints.

Here, with `ge=1`, `item_id` will need to be an integer number "`g`reater than or `e`qual" to `1`.

Se você capturar uma exceção em uma dependência com `yield`, a menos que você esteja levantando outra `HTTPException` ou coisa parecida, **você deve relançar a exceção original**.

Você pode relançar a mesma exceção utilizando `raise`:

{* ../../docs_src/dependencies/tutorial008d_an_py39.py hl[17] *}

And all of them can use `yield`.

In this case `dependency_c`, to execute its exit code, needs the value from `dependency_b` (here named `dep_b`) to still be available.

And, in turn, `dependency_b` needs the value from `dependency_a` (here named `dep_a`) to be available for its exit code.

{* ../../docs_src/dependencies/tutorial008_an_py39.py hl[18:19,26:27] *}

    "groups" : [ {
      "testProject" : "largeJavaMultiProject",
      "comment" : "We only test the multi-project here since for the monolithic project we would have no cache hits. This would mean we actually would test incremental compilation.",
      "coverage" : {
        "per_commit" : [ "linux" ]
      }
    } ]
  }, {

Para lograr esto, el backend `:80` debe tener una lista de "orígenes permitidos".

En este caso, la lista tendría que incluir `http://localhost:8080` para que el frontend `:8080` funcione correctamente.
