Models Documentation¶

This section documents the data models used in Aura Art.

Core Models¶

Artwork Model¶

The Artwork model represents individual pieces of art in the collection. It is thought to be as flexible as possible, so most of the fields are optional.

Artist Model¶

The Artist model stores information about artists.

Collection Model¶

The Collection model groups related artworks together.

Exhibition Model¶

The Exhibition model tracks art exhibitions and shows.

Contact Models¶

Contact Model¶

The Contact model stores information about galleries, collectors, and other art professionals.

User Models¶

User Profile¶

The Profile model extends Django’s User model with additional fields.

Notes Models¶

Note Model¶

The Note model allows users to add personal notes to artworks and artists.

Model Relationships¶

The main relationships in the Aura Art data model are:

User has many Profiles and Notes
Artist creates many Artworks and can have Notes
Artwork can have many Notes and belongs to Collections
Collection contains many Artworks
Exhibition displays many Artworks
Contact can organize many Exhibitions

Model Methods¶

Common Methods¶

All models include common methods for:

String representation (__str__)
Absolute URL generation (get_absolute_url)
Metadata access (_meta)

Custom Methods¶

Each model includes custom methods specific to its functionality:

Artwork: get_image_url(), get_dimensions_display()
Artist: get_full_name(), get_artwork_count()
Collection: get_total_value(), get_artwork_count()
Exhibition: is_current(), get_duration()

Model Validation¶

Field Validation¶

Models include field-level validation for:

Required fields
Field length limits
Format validation (email, URL, etc.)
Value constraints

Model Validation¶

Custom model validation includes:

Business logic validation
Cross-field validation
Unique constraint validation
Related object validation

Database Indexes¶

Performance Optimization¶

Models include database indexes for:

Frequently queried fields
Foreign key relationships
Search fields
Date/time fields

Migration Strategy¶

Model Changes¶

When modifying models:

Create a new migration file
Test the migration on a copy of production data
Apply the migration during maintenance windows
Update related code and tests

Data Integrity¶

Models maintain data integrity through:

Foreign key constraints
Unique constraints
Check constraints
Cascade delete rules
