Injected Context for Model Class not picked up

[lowmann15]

Bug

Trying to use the validation context within one of my Model classes which pydantic offers is not possible.

Current Behavior

Example code to reproduce:

from odmantic import Model
from pydantic import ValidationInfo, field_validator


class MyModel(Model):
    text: str

    @field_validator('text')
    @classmethod
    def remove_stopwords(cls, v: str, info: ValidationInfo):
        context = info.context
        if context:
            stopwords = context.get('stopwords', set())
            v = ' '.join(w for w in v.split() if w.lower() not in stopwords)
        return v


data = {'text': 'This is an example document'}
print(MyModel.model_validate(data))  # no context
#> text='This is an example document'
print(MyModel.model_validate(data, context={'stopwords': ['this', 'is', 'an']}))
#> text='This is an example document'
print(MyModel.model_validate(data, context={'stopwords': ['document']}))
#> text='This is an example document'

Expected behavior

The output should not be

text='This is an example document'
text='This is an example document'
text='This is an example document'

but

text='This is an example document'
text='example document'
text='This is an example'

according to the context that should filter out the words per use case.
