Create `Hero` model, the `secret_name` field aliased to `secretName`\r\n2. Post data\r\n```json\r\n{\r\n  \"name\": \"string\",\r\n  \"secretName\": \"string\",\r\n  \"age\": 0\r\n}\r\n```\r\n3. Then get `hero.secret_name` is `None`\r\n4. If I replace `hero: Hero` to `hero: HeroPydantic`, the `hero.secret_name` can get correct value from post data. But the strainge thing is that I can get correct `hero.secret_name` by  `hero: Hero = Hero.parse_obj(hero.dict(by_alias=True))`\r\n\r\n**So it seems that alias argument in sqlmodel seems not working for converting body from post data**, I have to write two models in order to achieve that.\r\n\r\n### Operating System\r\n\r\nWindows\r\n\r\n### Operating System Details\r\n\r\n_No response_\r\n\r\n### SQLModel Version\r\n\r\n0.0.6\r\n\r\n### Python Version\r\n\r\n3.7.6\r\n\r\n### Additional Context\r\n\r\n_No response_","author":{"url":"https://github.com/boh5","@type":"Person","name":"boh5"},"datePublished":"2022-07-12T15:31:07.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":16},"url":"https://github.com/374/sqlmodel/issues/374"}
