But in some cases you need to return a different status code than the default.

## Use case { #use-case }

For example, imagine that you want to return an HTTP status code of "OK" `200` by default.

But if the data didn't exist, you want to create it, and return an HTTP status code of "CREATED" `201`.

                                    "Expected text value 'http://www.apache.org/path/to/parent/child-artifact-id/' but was "
                                            + "'http://www.apache.org/path/to/parent/../child-artifact-id/'"),
                    afe.getMessage());
        }
        // but ok from repo: local disk is ignored
        testInheritance("tricky-flat-artifactId-urls", true);

All the same `parameters`, `responses`, `dependencies`, `tags`, etc.

/// tip

In this example, the variable is called `router`, but you can name it however you want.

///

We are going to include this `APIRouter` in the main `FastAPI` app, but first, let's check the dependencies and another `APIRouter`.

## Dependencies { #dependencies }

And you don't need to declare anything else for that parameter, so you don't really need to use `Query`.

But you still need to use `Path` for the `item_id` path parameter. And you don't want to use `Annotated` for some reason.

Python will complain if you put a value with a "default" before a value that doesn't have a "default".

But you can re-order them, and have the value without a default (the query parameter `q`) first.

		t.Errorf("Name fields shouldn't be changed if untouched, but got %v", animal.Name)
	}

	// When changing a field with a default value, the change must occur
	animal.Name = "amazing horse"
	DB.Save(&animal)
	DB.First(&animal, animal.Counter)
	if animal.Name != "amazing horse" {
		t.Errorf("Update a filed with a default value should occur. But got %v\n", animal.Name)
	}

				}
			})

			if len(gots) != len(test.wants) {
				t.Fatalf("Expected %d objects but got %d", len(test.wants), len(gots))
			}
			if slices.CompareFunc(gots, test.wants, func(g, w ObjectInfo) int {
				if g.VersionID == w.VersionID {
					return 0
				}
				return -1
			}) != 0 {
				t.Fatalf("Expected %v but got %v", test.wants, gots)
			}
			// verify the objects to be deleted
			close(workers[0])

		t.Errorf("errors happened when update: %v", res.Error)
	} else if res.RowsAffected != 1 {
		t.Errorf("rows affected should be 1, but got : %v", res.RowsAffected)
	} else if user.Age != 5 {
		t.Errorf("Age should equals to 5, but got %v", user.Age)
	} else if user.Active != true {
		t.Errorf("Active should be true, but got %v", user.Active)
	}
	checkUpdatedAtChanged("Updates with map", user.UpdatedAt)
	checkOtherData("Updates with map")

### Edit it { #edit-it }

It's a very simple program.

But now imagine that you were writing it from scratch.

At some point you would have started the definition of the function, you had the parameters ready...

But then you have to call "that method that converts the first letter to upper case".

Was it `upper`? Was it `uppercase`? `first_uppercase`? `capitalize`?

            String formattedLeft = CollectionUtils.join("\n", keptAccessors.keySet());
            throw new RuntimeException("The following accessors were upgraded, but didn't match any removed/changed method:\n\n" + formattedLeft);
        }

        // Find accessors that were removed but shouldn't be
        Map<AccessorKey, ReplacedAccessor> removedAccessors = new HashMap<>(oldAccessorsOfUpgradedProperties);

### Required, can be `None` { #required-can-be-none }

You can declare that a parameter can accept `None`, but that it's still required. This would force clients to send a value, even if the value is `None`.

To do that, you can declare that `None` is a valid type but simply do not declare a default value:
