Pydantic Models

Create Pydantic models following the multi-model pattern for clean API contracts.

Quick Start

Copy the template from assets/template.py and replace placeholders:

• {{ResourceName}} → PascalCase name (e.g., Project)
• {{resource_name}} → snake_case name (e.g., project)

Multi-Model Pattern

Model	Purpose
Base	Common fields shared across models
Create	Request body for creation (required fields)
Update	Request body for updates (all optional)
Response	API response with all fields
InDB	Database document with doc_type

camelCase Aliases

class MyModel(BaseModel):
    workspace_id: str = Field(..., alias="workspaceId")
    created_at: datetime = Field(..., alias="createdAt")
    
    class Config:
        populate_by_name = True  # Accept both snake_case and camelCase

Optional Update Fields

class MyUpdate(BaseModel):
    """All fields optional for PATCH requests."""
    name: Optional[str] = Field(None, min_length=1)
    description: Optional[str] = None

Database Document

class MyInDB(MyResponse):
    """Adds doc_type for Cosmos DB queries."""
    doc_type: str = "my_resource"

Integration Steps

1. Create models in src/backend/app/models/
2. Export from src/backend/app/models/__init__.py
3. Add corresponding TypeScript types
