Sure, here's the `comments.py` file for the `app/api/v1/schemas/` directory in the `blog_app_igblf` FastAPI backend:

from datetime import datetime
from typing import Optional

from pydantic import BaseModel, Field

from app.db.base_class import Base

class CommentBase(BaseModel):
    content: str = Field(..., min_length=1, max_length=1000)

class CommentCreate(CommentBase):
    pass

class CommentUpdate(CommentBase):
    pass

class CommentInDBBase(CommentBase):
    id: int
    created_at: datetime
    updated_at: Optional[datetime] = None
    post_id: int

    class Config:
        orm_mode = True

class Comment(CommentInDBBase):
    pass

class CommentInDB(CommentInDBBase):
    pass

This file defines the following Pydantic models for comments:








Note: You may need to adjust the import statements and the `Base` class import based on the actual structure of your `blog_app_igblf` project.
