CRUDAdmin v0.4.0 - Session Configuration API Overhaul

🚨 BREAKING CHANGES - Migration Required

This release introduces a complete overhaul of the session backend configuration API, replacing the old method-based approach with a cleaner constructor-based system. All existing code using session backends will need to be updated.

⚠️ Removed Session Methods

The following session configuration methods have been removed and will cause errors if used:

# ❌ REMOVED - These methods no longer exist:
admin.use_redis_sessions(...)
admin.use_memcached_sessions(...)
admin.use_memory_sessions(...)
admin.use_database_sessions(...)
admin._recreate_session_manager()

🔄 Required Migration Steps

Before (v0.3.x):

from crudadmin import CRUDAdmin

# Old method-based Redis configuration - WILL NOT WORK in v0.4.0+
admin = CRUDAdmin(
    session=get_session,
    SECRET_KEY="your-secret-key",
    # Basic setup first
)

# ❌ Old method calls that no longer work
admin.use_redis_sessions(
    host="localhost",
    port=6379,
    db=0,
    password="mypassword",
    pool_size=20,
    connect_timeout=10
)

# Old Memcached method - WILL NOT WORK in v0.4.0+
admin.use_memcached_sessions(
    servers=["localhost:11211"],
    pool_size=10
)

After (v0.4.0+):

from crudadmin import CRUDAdmin
from crudadmin.session.configs import RedisConfig, MemcachedConfig

# ✅ Method 1: Using configuration objects (recommended)
redis_config = RedisConfig(
    host="localhost",
    port=6379,
    db=0,
    password="mypassword",
    pool_size=20,
    connect_timeout=10
)

admin = CRUDAdmin(
    session=get_session,
    SECRET_KEY="your-secret-key",
    session_backend="redis",
    redis_config=redis_config
)

# ✅ Method 2: Using dictionary configuration
admin = CRUDAdmin(
    session=get_session,
    SECRET_KEY="your-secret-key",
    session_backend="redis",
    redis_config={
        "host": "localhost",
        "port": 6379,
        "db": 0,
        "password": "mypassword",
        "pool_size": 20,
        "connect_timeout": 10
    }
)

# ✅ Method 3: Using Redis URL
admin = CRUDAdmin(
    session=get_session,
    SECRET_KEY="your-secret-key",
    session_backend="redis",
    redis_config={"url": "redis://:mypassword@localhost:6379/0"}
)

# ✅ New Memcached configuration
admin = CRUDAdmin(
    session=get_session,
    SECRET_KEY="your-secret-key",
    session_backend="memcached",
    memcached_config={
        "servers": ["localhost:11211"],
        "pool_size": 10
    }
)

✨ New Features

🗂️ New Configuration Module

• New module: crudadmin.session.configs with configuration classes:
  • RedisConfig - Redis backend configuration with URL parsing and validation
  • MemcachedConfig - Memcached backend configuration with server list support

    session=get_session,
    SECRET_KEY="key", 
    session_backend="redis",
    redis_config={"host": "localhost", "port": 6379, "db": 0}
)

📊 Enhanced Redis Configuration

• URL parsing: Full Redis URL support with automatic parameter extraction
• Connection validation: Pydantic validation for all Redis parameters
• Connection pooling: Proper connection pool size and timeout configuration
• ACL support: Full Redis 6.0+ ACL username/password authentication

🔗 Enhanced Memcached Configuration

• Connection pooling: Configurable pool sizes for better performance
• Validation: Automatic validation of server addresses and ports

🎯 Simplified API

• No method chaining: All configuration done at construction time
• Better error handling: Configuration errors caught immediately at startup
• Cleaner code: No need for manual session manager recreation
• Documentation: Enhanced docstrings with configuration examples

0.3.4

Using select_schema to Exclude Fields from Read Operations

Some database field types can cause issues in admin panels. The most common example is PostgreSQL's TSVector type used for full-text search, which can trigger NotImplementedError when trying to display records.

The select_schema parameter allows you to exclude problematic fields from all read operations while keeping them available for create/update operations.

Use select_schema when you encounter:

• TSVector fields causing NotImplementedError in admin views
• Large binary fields that slow down list views
• Computed fields that don't need to be displayed
• Sensitive fields that should be hidden from admin users
• Complex JSON fields that break admin display formatting

Basic Example: Excluding TSVector Fields

from sqlalchemy import Column, Integer, String, Text
from sqlalchemy_utils import TSVectorType
from pydantic import BaseModel
from typing import Optional
from datetime import datetime

# SQLAlchemy model with TSVector for full-text search
class Document(Base):
    __tablename__ = "documents"

    id = Column(Integer, primary_key=True)
    title = Column(String(200), nullable=False)
    content = Column(Text, nullable=False)
    created_at = Column(DateTime, default=func.now())

    # This field causes NotImplementedError in admin views
    search_vector = Column(TSVectorType('title', 'content'))

# Schemas for create/update (no search_vector)
class DocumentCreate(BaseModel):
    title: str = Field(..., min_length=1, max_length=200)
    content: str = Field(..., min_length=1)

class DocumentUpdate(BaseModel):
    title: Optional[str] = Field(None, min_length=1, max_length=200)
    content: Optional[str] = None

# Schema for read operations (excludes problematic field)
class DocumentSelect(BaseModel):
    id: int
    title: str
    content: str
    created_at: datetime
    # search_vector field intentionally excluded!

# Register with admin
admin.add_view(
    model=Document,
    create_schema=DocumentCreate,
    update_schema=DocumentUpdate,
    select_schema=DocumentSelect,  # ✅ TSVector excluded from reads
    allowed_actions={"view", "create", "update", "delete"}
)
