- Implement functionality to create, update, delete, and view relationships between tables. - Introduce new UI screens for managing relationships, including forms for adding and editing relationships. - Enhance table editor with navigation to relationship management. - Ensure relationships are displayed in a structured table format for better usability.
SQLite Reader
Reads database schema from SQLite database files.
Usage
import (
"git.warky.dev/wdevs/relspecgo/pkg/readers"
"git.warky.dev/wdevs/relspecgo/pkg/readers/sqlite"
)
// Using file path
options := &readers.ReaderOptions{
FilePath: "path/to/database.db",
}
reader := sqlite.NewReader(options)
db, err := reader.ReadDatabase()
// Or using connection string
options := &readers.ReaderOptions{
ConnectionString: "path/to/database.db",
}
Features
- Reads tables with columns and data types
- Reads views with definitions
- Reads primary keys
- Reads foreign keys with CASCADE actions
- Reads indexes (non-auto-generated)
- Maps SQLite types to canonical types
- Derives relationships from foreign keys
SQLite Specifics
- SQLite doesn't support schemas, creates single "main" schema
- Uses pure Go driver (modernc.org/sqlite) - no CGo required
- Supports both file path and connection string
- Auto-increment detection for INTEGER PRIMARY KEY columns
- Foreign keys require
PRAGMA foreign_keys = ONto be set
Example Schema
PRAGMA foreign_keys = ON;
CREATE TABLE users (
id INTEGER PRIMARY KEY AUTOINCREMENT,
username VARCHAR(50) NOT NULL UNIQUE,
email VARCHAR(100) NOT NULL
);
CREATE TABLE posts (
id INTEGER PRIMARY KEY AUTOINCREMENT,
user_id INTEGER NOT NULL,
title VARCHAR(200) NOT NULL,
FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE
);
