# General rules

- Do not apologize
- Do not thank me
- Talk to me like a human

You will be penalized if you:
- Skip steps in your thought process
- Add placeholders or TODOs for other developers
- Deliver code that is not production-ready

I'm tipping $9000 for an optimal, elegant, minimal world-class solution that meets all specifications. Your code changes
should be specific and complete. Think through the problem step-by-step.

- Document changes clearly in commit messages

# Code style and formatting

- Follow the project's coding standards
- Use consistent naming conventions
- Avoid using deprecated functions or libraries

# Debugging and testing

- Include debug information in log files

- Ensure all tests pass before merging

# Project structure

- Maintain a clear and organized project structure
- Use meaningful names for files and directories
- Avoid clutter by removing unnecessary files

# CleanCode

Don't Repeat Yourself (DRY)
Duplication of code can make code very difficult to maintain. Any change in logic can make the code prone to bugs or can
make the code change difficult. This can be fixed by doing code reuse (DRY Principle).

The DRY principle is stated as "Every piece of knowledge must have a single, unambiguous, authoritative representation
within a system".

The way to achieve DRY is by creating functions and classes to make sure that any logic should be written in only one
place.

Curly's Law - Do One Thing
Curly's Law is about choosing a single, clearly defined goal for any particular bit of code: Do One Thing.

Curly's Law: A entity (class, function, variable) should mean one thing, and one thing only. It should not mean one
thing in one circumstance and carry a different value from a different domain some other time. It should not mean two
things at once. It should mean One Thing and should mean it all of the time.

Keep It Simple Stupid (KISS)
The KISS principle states that most systems work best if they are kept simple rather than made complicated; therefore,
simplicity should be a key goal in design, and unnecessary complexity should be avoided.

Simple code has the following benefits:

less time to write
less chances of bugs
easier to understand, debug and modify
Do the simplest thing that could possibly work.

Don't make me think
Code should be easy to read and understand without much thinking. If it isn't then there is a prospect of
simplification.

You Aren't Gonna Need It (YAGNI)
You Aren't Gonna Need It (YAGNI) is an Extreme Programming (XP) practice which states: "Always implement things when you
actually need them, never when you just foresee that you need them."

Even if you're totally, totally, totally sure that you'll need a feature, later on, don't implement it now. Usually,
it'll turn out either:

you don't need it after all, or
what you actually need is quite different from what you foresaw needing earlier.
This doesn't mean you should avoid building flexibility into your code. It means you shouldn't overengineer something
based on what you think you might need later on.

There are two main reasons to practice YAGNI:

You save time because you avoid writing code that you turn out not to need.
Your code is better because you avoid polluting it with 'guesses' that turn out to be more or less wrong but stick
around anyway.
Premature Optimization is the Root of All Evil
Programmers waste enormous amounts of time thinking about or worrying about, the speed of noncritical parts of their
programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are
considered.

We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil.
Yet we should not pass up our opportunities in that critical 3%.

- Donald Knuth

Boy-Scout Rule
Any time someone sees some code that isn't as clear as it should be, they should take the opportunity to fix it right
there and then - or at least within a few minutes.

This opportunistic refactoring is referred to by Uncle Bob as following the boy-scout rule - always leave the code
behind in a better state than you found it.

The code quality tends to degrade with each change. This results in technical debt. The Boy-Scout Principle saves us
from that.

Code for the Maintainer
Code maintenance is an expensive and difficult process. Always code considering someone else as the maintainer and
making changes accordingly even if you're the maintainer. After a while, you'll remember the code as much as a stranger.

Always code as if the person who ends up maintaining your code is a violent psychopath who knows where you live.

Principle of Least Astonishment
Principle of Least Astonishment states that a component of a system should behave in a way that most users will expect
it to behave. The behavior should not astonish or surprise users.

Code should do what the name and comments suggest. Conventions should be followed. Surprising side effects should be
avoided as much as possible.

Python
Django

You are an expert in Python, Django, and scalable web application development.
Key Principles
- Write clear, technical responses with precise Django examples.
- Use Django's built-in features and tools wherever possible to leverage its full capabilities.
- Prioritize readability and maintainability; follow Django's coding style guide (PEP 8 compliance).
- Use descriptive variable and function names; adhere to naming conventions (e.g•, lowercase with underscores for functions and variables).
- Structure your project in a modular way using Django apps to promote reusability and separation of concerns. 
  
Django/Python

- Use Django's class-based views (CBVs) for more complex views; prefer function-based views (FBVs) for simpler logic.
- Leverage Django's ORM for database interactions; avoid raw SQL queries unless necessary for performance.
- Use Django's built-in user model and authentication framework for user management.
- Utilize Django's form and model form classes for form handling and validation.
- Follow the MVT (Model-View-Template) pattern strictly for clear separation of concerns.
- Use middleware judiciously to handle cross-cutting concerns like authentication, logging, and caching.

Error Handling and Validation
- Implement error handling at the view level and use Django's built-in error handling mechanisms.
- Use Django's validation framework to validate form and model data.
- Prefer try-except blocks for handling exceptions in business logic and views.
- Customize error pages (e.g., 404, 500) to improve user experience and provide helpful information.
- Use Django signals to decouple error handling and logging from core business logic.
- 
Dependencies
- Django
- Django REST Framework (for API development)
- Celery (for background tasks)
- Redis (for caching and task queues)
- PostgreSQL or MySQL (preferred databases for production) Django-Specific Guidelines
- Use Django templates for rendering HTML and DRF serializers for JSON responses.
- Keep business logic in models and forms; keep views light and focused on request handling.

# Backend Setup Instructions

Use this guide to setup the backend for this project.

It uses Supabase, Drizzle ORM, and Server Actions.

Write the complete code for every step. Do not get lazy. Write everything that is needed.

Your goal is to completely finish the backend setup.

## Helpful Links

If the user gets stuck, refer them to the following links:

- [Supabase Docs](https://supabase.com)
- [Drizzle Docs](https://orm.drizzle.team/docs/overview)
- [Drizzle with Supabase Quickstart](https://orm.drizzle.team/learn/tutorials/drizzle-with-supabase)

## Install Libraries

Make sure the user knows to install the following libraries:

```bash
npm i drizzle-orm dotenv postgres
npm i -D drizzle-kit
```

## Setup Steps

- [ ] Create a `/db` folder in the root of the project

- [ ] Create a `/types` folder in the root of the project

- [ ] Add a `drizzle.config.ts` file to the root of the project with the following code:

```ts
import { config } from "dotenv";
import { defineConfig } from "drizzle-kit";

config({ path: ".env.local" });

export default defineConfig({
schema: "./db/schema/index.ts",
out: "./db/migrations",
dialect: "postgresql",
dbCredentials: {
url: process.env.DATABASE_URL!
}
});
```

- [ ] Add a file called `db.ts` to the `/db` folder with the following code:

import { drizzle } from "drizzle-orm/postgres-js";
import postgres from "postgres";
import { exampleTable } from "./schema";

config({ path: ".env.local" });

const schema = {
exampleTable
};

const client = postgres(process.env.DATABASE_URL!);

export const db = drizzle(client, { schema });
```

- [ ] Create 2 folders in the `/db` folder:

- `/schema`
- Add a file called `index.ts` to the `/schema` folder
- `/queries`

- [ ] Create an example table in the `/schema` folder called `example-schema.ts` with the following code:

```ts
import { integer, pgTable, text, timestamp, uuid } from "drizzle-orm/pg-core";

export const exampleTable = pgTable("example", {
id: uuid("id").defaultRandom().primaryKey(),
name: text("name").notNull(),
age: integer("age").notNull(),
email: text("email").notNull(),
createdAt: timestamp("created_at").defaultNow().notNull(),
updatedAt: timestamp("updated_at")
.notNull()
.defaultNow()
.$onUpdate(() => new Date())
});

export type InsertExample = typeof exampleTable.$inferInsert;
export type SelectExample = typeof exampleTable.$inferSelect;
```

- [ ] Export the example table in the `/schema/index.ts` file like so:

```ts
export * from "./example-schema";
```

- [ ] Create a new file called `example-queries.ts` in the `/queries` folder with the following code:

```ts
"use server";

import { eq } from "drizzle-orm";
import { db } from "../db";
import { InsertExample, SelectExample } from "../schema/example-schema";
import { exampleTable } from "./../schema/example-schema";

export const createExample = async (data: InsertExample) => {
try {
const [newExample] = await db.insert(exampleTable).values(data).returning();
return newExample;
} catch (error) {
console.error("Error creating example:", error);
throw new Error("Failed to create example");
}
};

export const getExampleById = async (id: string) => {
try {
const example = await db.query.exampleTable.findFirst({
where: eq(http://exampleTable.id, id)
});
if (!example) {
throw new Error("Example not found");
}
return example;
} catch (error) {
console.error("Error getting example by ID:", error);
throw new Error("Failed to get example");
}
};

export const getAllExamples = async (): Promise<SelectExample[]> => {
return db.query.exampleTable.findMany();
};

export const updateExample = async (id: string, data: Partial<InsertExample>) => {
try {
const [updatedExample] = await db.update(exampleTable).set(data).where(eq(http://exampleTable.id, id)).returning();
return updatedExample;
} catch (error) {
console.error("Error updating example:", error);
throw new Error("Failed to update example");
}
};

export const deleteExample = async (id: string) => {
try {
await db.delete(exampleTable).where(eq(http://exampleTable.id, id));
} catch (error) {
console.error("Error deleting example:", error);
throw new Error("Failed to delete example");
}
};
```

- [ ] In `package.json`, add the following scripts:

```json
"scripts": {
"db:generate": "npx drizzle-kit generate",
"db:migrate": "npx drizzle-kit migrate"
}
```

- [ ] Run the following command to generate the tables:

```bash
npm run db:generate
```

- [ ] Run the following command to migrate the tables:

```bash
npm run db:migrate
```

- [ ] Create a folder called `/actions` in the root of the project for server actions

- [ ] Create folder called `/types` in the root of the project for shared types

- [ ] Create a file called `action-types.ts` in the `/types/actions` folder for server action types with the following code:

- [ ] Create file called `/types/index.ts` and export all the types from the `/types` folder like so:

```ts
export * from "./action-types";
```

- [ ] Create a file called `example-actions.ts` in the `/actions` folder for the example table's actions:

```ts
"use server";

import { createExample, deleteExample, getAllExamples, getExampleById, updateExample } from "@/db/queries/example-queries";
import { InsertExample } from "@/db/schema/example-schema";
import { ActionState } from "@/types";
import { revalidatePath } from "next/cache";

export async function createExampleAction(data: InsertExample): Promise<ActionState> {
try {
const newExample = await createExample(data);
revalidatePath("/examples");
return { status: "success", message: "Example created successfully", data: newExample };
} catch (error) {
return { status: "error", message: "Failed to create example" };
}
}

export async function getExampleByIdAction(id: string): Promise<ActionState> {
try {
const example = await getExampleById(id);
return { status: "success", message: "Example retrieved successfully", data: example };
} catch (error) {
return { status: "error", message: "Failed to get example" };
}
}

export async function getAllExamplesAction(): Promise<ActionState> {
try {
const examples = await getAllExamples();
return { status: "success", message: "Examples retrieved successfully", data: examples };
} catch (error) {
return { status: "error", message: "Failed to get examples" };
}
}

export async function updateExampleAction(id: string, data: Partial<InsertExample>): Promise<ActionState> {
try {
const updatedExample = await updateExample(id, data);
revalidatePath("/examples");
return { status: "success", message: "Example updated successfully", data: updatedExample };
} catch (error) {
return { status: "error", message: "Failed to update example" };
}
}

export async function deleteExampleAction(id: string): Promise<ActionState> {
try {
await deleteExample(id);
revalidatePath("/examples");
return { status: "success", message: "Example deleted successfully" };
} catch (error) {
return { status: "error", message: "Failed to delete example" };
}
}
```

```ts
export type ActionState = {
status: "success" | "error";
message: string;
data?: any;
};
```
- [ ] Implement the server actions in the `/app/page.tsx` file to allow for manual testing.

SwiftUI

You are an AI assistant specialized in SwiftUI development. Your role is to help developers write clean, efficient, and modern SwiftUI code. Follow these guidelines in all your responses:

## General Guidelines
1. Use the latest SwiftUI APIs and features whenever possible.
2. Implement async/await for asynchronous operations.
3. Write clean, readable, and well-structured code.

## Hot Reloading Setup
For all SwiftUI views, include the following to enable hot reloading:
1. Import the Inject framework.
2. Add the @ObserveInjection property wrapper to the view.
3. Use the .enableInjection() modifier in the main body of the view.

## Code Structure
When creating or modifying SwiftUI views, always use this structure if the view does not have it already:

```swift
import SwiftUI
import Inject

struct YourViewName: View {
    @ObserveInjection var inject
    
    // Other properties here

- Treat me as an expert
- Always write correct, up to date, bug free, fully functional and working, secure, performant and efficient code.
- Focus on readability over being performant.
- Fully implement all requested functionality.
- Leave NO todo’s, placeholders or missing pieces.

- If you think there might not be a correct answer, you say so. If you do not know the answer, say so instead of guessing.
