Since **Pydantic v2** was released, the generated OpenAPI is a bit more exact and **correct** than before. 😎

In fact, in some cases, it will even have **two JSON Schemas** in OpenAPI for the same Pydantic model, for input and output, depending on if they have **default values**.

Let's see how that works and how to change it if you need to do that.

## Pydantic Models for Input and Output { #pydantic-models-for-input-and-output }

		err = msgp.WrapError(err)
		return
	}
	return
}

// MarshalMsg implements msgp.Marshaler
func (z Type) MarshalMsg(b []byte) (o []byte, err error) {
	o = msgp.Require(b, z.Msgsize())
	o = msgp.AppendInt(o, int(z))
	return
}

// UnmarshalMsg implements msgp.Unmarshaler
func (z *Type) UnmarshalMsg(bts []byte) (o []byte, err error) {
	{
		var zb0001 int
		zb0001, bts, err = msgp.ReadIntBytes(bts)

 The metadata file name is:

 * <<<maven-metadata.xml>>> in a remote repository,

 * <<<maven-metadata-\<repo-id>.xml>>> in a local repository, for metadata from a repository with <<<repo-id>>> identifier.

 Depending on what the directory represents ("groupId", "groupId/artifactId" or "groupId/artifactId/version"),
 the Maven Repository Metadata file contains 3 different sets of metadata:

            int result = applyGoal.execute(context);

            // Verify success
            assertEquals(0, result, "Apply should succeed");

            // Verify POM was potentially modified (depending on strategy applicability)
            String pomContent = Files.readString(pomFile);
            assertTrue(
                    pomContent.contains("<groupId>com.example</groupId>"),

   * the XML specification.
   *
   * <p>This escaper does not escape non-ASCII characters to their numeric character references
   * (NCR). Any non-ASCII characters appearing in the input will be preserved in the output.
   * Specifically "\r" (carriage return) is preserved in the output, which may result in it being
   * silently converted to "\n" when the XML is parsed.

   * com.google.common.testing.junit3.TearDownTestCase} and {@code
   * com.google.common.testing.junit4.TearDownTestCase} for example.
   *
   * <p>A failing {@link TearDown} may or may not fail a tl4j test, depending on the version of
   * JUnit test case you are running under. To avoid failing in the face of an exception regardless
   * of JUnit version, implement a {@link SloppyTearDown} instead.
