+This guide will walk you through the process of setting up the database connection and repository in your src/main.rs file, focusing on the SeaORM setup without the Axum-specific parts.
+Step 1: Import Required Dependencies
+First, ensure you have the necessary imports at the top of your src/main.rs file:
+rustCopyuse std::sync::Arc;
+use domain::{db, repository::Repository};
+
+mod config;
+
+use crate::config::Settings;
+Step 2: Set Up the Database Connection
+Inside your main function, add the following code to establish the database connection:
+rustCopy#[tokio::main]
+async fn main() -> anyhow::Result<()> {
+    let settings = Settings::new().expect("Failed to load settings");
+
+    let conn = Arc::new(db::initialize(&settings.database_url).await?);
+    // ... rest of the main function
+}
+This code does the following:
+
+Loads the application settings (including the database URL)
+Initializes the database connection using the db::initialize function
+Wraps the connection in an Arc for safe sharing across threads
+
+Step 3: Create the Repository
+After setting up the connection, create the repository:
+rustCopylet repository = Repository::new(conn);
+This line creates a new Repository instance using the database connection.
+Complete main.rs Example
+Here's how your src/main.rs file should look with just the database and repository setup:
+rustCopyuse std::sync::Arc;
+use domain::{db, repository::Repository};
+
+mod config;
+
+use crate::config::Settings;
+
+#[tokio::main]
+async fn main() -> anyhow::Result<()> {
+    let settings = Settings::new().expect("Failed to load settings");
+
+    let conn = Arc::new(db::initialize(&settings.database_url).await?);
+    let repository = Repository::new(conn);
+
+    // You can now use the `repository` for database operations
+
+    Ok(())
+}
+

+Create the repository functions for the user type. We are implementing the repository pattern. Don't leak any orm abstractions outside this model. Make sure you add the user repository to the main repository https://github.com/johns10/axum_example/blob/main/domain/src/post/repository.rs https://github.com/johns10/axum_example/blob/main/domain/src/repository.rs

# 2024-09-08 18:48:33.620659
+I think you need to refactor the `UserRepository` to actually implement the repository pattern. You didn't do the trait implementation. You didn't handle error mapping to an internally defined type. Please modify https://github.com/johns10/axum_example/blob/main/domain/src/post/repository.rs
