When I try to run the sample from documentation, it seems that there are pydantic v2 migration issues not fixed in 0.6.1. Could you please have a look at my error output as above?

my pydantic env is as below:

pip show pydantic Name: pydantic Version: 2.0.3 Summary: Data validation using Python type hints Home-page: Author: Author-email: Samuel Colvin [email protected], Eric Jolibois [email protected], Hasan Ramezani [email protected], Adrian Garcia Badaracco [email protected], Terrence Dorsey [email protected], David Montague [email protected] License: Location: /Users/peter42/opt/miniconda3/envs/pydant2/lib/python3.10/site-packages Requires: annotated-types, pydantic-core, typing-extensions Required-by: fastapi, fastapi_amis_admin

I got it. In pydantic v2, pydantic_settings was moved to serperate package, and I have to manually install it by 'pip install pydantic_settings'. The issue was solved.

In the example about FormAdmin in docs '''from fastapi_amis_admin.models.fields import Field

register FormAdmin

@site.register_admin class UserLoginFormAdmin(admin.FormAdmin): page_schema = 'UserLoginForm' # set form information, optional form = Form(title='This is a test login form', submitText='login')

# create form schema
class schema(BaseModel):
    username: str = Field(..., title='username', min_length=3, max_length=30)
    password: str = Field(..., title='password')

# handle form submission data
async def handle(self, request: Request, data: BaseModel, **kwargs) -> BaseApiOut[Any]:
    if data.username == 'amisadmin' and data.password == 'amisadmin':
        return BaseApiOut(msg='Login successfully!', data={'token': 'xxxxxx'})
    return BaseApiOut(status=-1, msg='Incorrect username or password!')

''' However, pydantic.typing.NoArgAnyCallable was removed from pydantic v2 according to the migration guide of Pydantic site. And I got the error report Undefined type is not in pydantic.fields module. I checked pydantic v2 source code, it doesn't exsit there.
