# Body - Multiple Parameters { #body-multiple-parameters }

Now that we have seen how to use `Path` and `Query`, let's see more advanced uses of request body declarations.

## Mix `Path`, `Query` and body parameters { #mix-path-query-and-body-parameters }

First, of course, you can mix `Path`, `Query` and request body parameter declarations freely and **FastAPI** will know what to do.

    private static final long TEST_LAST_WRITE_TIME = System.currentTimeMillis() - 3600000L; // 1 hour ago
    private static final long TEST_CHANGE_TIME = System.currentTimeMillis(); // now
    private static final int TEST_ATTRIBUTES = 0x00000020; // FILE_ATTRIBUTE_ARCHIVE

    @BeforeEach
    void setUp() {
        fileBasicInfo = new FileBasicInfo();
    }

    @Test

{* ../../docs_src/extending_openapi/tutorial001.py hl[2,15:21] *}

### Modify the OpenAPI schema { #modify-the-openapi-schema }

Now you can add the ReDoc extension, adding a custom `x-logo` to the `info` "object" in the OpenAPI schema:

{* ../../docs_src/extending_openapi/tutorial001.py hl[22:24] *}

### Cache the OpenAPI schema { #cache-the-openapi-schema }

Notice that now we don't create a default instance `settings = Settings()`.

### The main app file { #the-main-app-file }

Now we create a dependency that returns a new `config.Settings()`.

{* ../../docs_src/settings/app02_an_py39/main.py hl[6,12:13] *}

/// tip

We'll discuss the `@lru_cache` in a bit.

For now you can assume `get_settings()` is a normal function.

At this point you have the *callback path operation(s)* needed (the one(s) that the *external developer*  should implement in the *external API*) in the callback router you created above.

Now use the parameter `callbacks` in *your API's path operation decorator* to pass the attribute `.routes` (that's actually just a `list` of routes/*path operations*) from that callback router:

package gorm

import (
	"database/sql"
	"database/sql/driver"
	"encoding/json"
	"reflect"

	"github.com/jinzhu/now"
	"gorm.io/gorm/clause"
	"gorm.io/gorm/schema"
)

type DeletedAt sql.NullTime

// Scan implements the Scanner interface.
func (n *DeletedAt) Scan(value interface{}) error {
	return (*sql.NullTime)(n).Scan(value)
}

// Value implements the driver Valuer interface.

func (l *ReplicationLastHour) addsize(sz int64) {
	minutes := time.Now().Unix() / 60
	l.forwardTo(minutes)
	winIdx := minutes % 60
	l.Totals[winIdx].merge(AccElem{Total: minutes, Size: sz, N: 1})
	l.LastMin = minutes
}

// Merge all recorded counts of last hour into one
func (l *ReplicationLastHour) getTotal() AccElem {
	var res AccElem
	minutes := time.Now().Unix() / 60
	l.forwardTo(minutes)

# Using the Request Directly { #using-the-request-directly }

Up to now, you have been declaring the parts of the request that you need with their types.

Taking data from:

* The path as parameters.
* Headers.
* Cookies.
* etc.

And by doing so, **FastAPI** is validating that data, converting it and generating documentation for your API automatically.

But there are situations where you might need to access the `Request` object directly.
