## Examples

|
||||||
|
### Comprehensive Example
|
||||||
|
|
||||||
|
For an example showcasing user management, comments, and follower relationships, see the example in `examples/postgres/users-comments-and-followers/`. This example demonstrates:
|
||||||
|
|
||||||
|
- User management and profile management
|
||||||
|
- Comment system with user associations
|
||||||
|
- Follower/following relationships (many-to-many)
|
||||||
|
- Interactive CLI interface with CRUD operations
|
||||||
|
- Database migrations and schema setup
|
||||||
|
|
||||||
|
To run the example:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Set up your database
|
||||||
|
export DATABASE_URL="postgres://username:password@localhost/georm_example"
|
||||||
|
|
||||||
|
# Run migrations
|
||||||
|
cargo sqlx migrate run
|
||||||
|
|
||||||
|
# Run the example
|
||||||
|
cd examples/postgres/users-comments-and-followers
|
||||||
|
cargo run help # For a list of all available actions
|
||||||
|
```
