## Create your data model

Then you declare your data model as a class that inherits from `BaseModel`.

Use standard Python types for all the attributes:

              <version>1.2.0</version>

              <models>
                <model>src/main/mdo/toolchains.mdo</model>

## あらゆる場所でのエディタサポート

エディタのサポートもどこでも受けることができます。

以下のようにリストの中の項目でも:

<img src="https://fastapi.tiangolo.com/img/tutorial/body-nested-models/image01.png">

Pydanticモデルではなく、`dict`を直接使用している場合はこのようなエディタのサポートは得られません。

しかし、それらについて心配する必要はありません。入力された辞書は自動的に変換され、出力も自動的にJSONに変換されます。

## 任意の`dict`のボディ

また、ある型のキーと別の型の値を持つ`dict`としてボディを宣言することもできます。

              <models>
                <model>src/main/mdo/maven.mdo</model>
              </models>
              <templates>
                <template>model.vm</template>
              </templates>
              <params>
                <param>packageModelV4=org.apache.maven.api.model</param>
                <param>isMavenModel=true</param>
              </params>

              <velocityBasedir>${project.basedir}/../../src/mdo</velocityBasedir>
              <version>1.2.0</version>

              </models>
              <templates>
                <template>model.vm</template>
              </templates>
              <params>
                <param>packageModelV4=org.apache.maven.api.metadata</param>

            org.apache.maven.model.Model model, ModelBuildingRequest request, ModelProblemCollector problems) {
        model.update(mergeDuplicates(model.getDelegate(), request, problems));
    }

    @Override
    public void injectDefaultValues(
            org.apache.maven.model.Model model, ModelBuildingRequest request, ModelProblemCollector problems) {

We'll fix these things by adding a few **extra models**. Here's where SQLModel will shine. ✨

### Create Multiple Models

In **SQLModel**, any model class that has `table=True` is a **table model**.

And any model class that doesn't have `table=True` is a **data model**, these ones are actually just Pydantic models (with a couple of small extra features). 🤓
