Example Code

from sqlmodel import Field, Relationship
from pydantic import Field as Field2

class User(SQLModel):
    fullname: str = Field(regex=r'^[A-Za-z0-9\- ]+$', max_length=128)
    fullname2: str = Field2(pattern=r'^[A-Za-z0-9\- ]+$', max_length=128)

fails = User(fullname='test', fullname2='test_failing') # Fails because it knows how to process the regex

succeeds = User(fullname='test_not_failing', fullname2='test') # Does not fail because the `regex` keyword is ignored

Description

I'm migrating from SQLModel 0.0.8 to SQLModel 0.0.14 using Pydantic 2.5.2. In SQLModel 0.0.8 I could use the regex keyword from the Field class to create a regular expression validation, but that doesn't work anymore. According to the docs of Pydantic, this should be pattern, but the Field object of SQLModel doesn't support that named argument.
