Description:

Set up a basic CRUD (Create, Read, Update, Delete) application using Golang, GORM, and SQLite for the "pay2post" app. This will include user authentication, handling payments, and managing posts. Steps:

Set Up Project Structure and Dependencies
    Create the project structure and initialize a Go module:

    sh

mkdir pay2post
cd pay2post
go mod init pay2post
go get -u gorm.io/gorm
go get -u gorm.io/driver/sqlite
go get -u github.com/gin-gonic/gin
go get -u github.com/stripe/stripe-go/v72

Create Database Models

Define models for User and Post:

go

// models/models.go
package models

import "gorm.io/gorm"

type User struct {
    gorm.Model
    Username string `gorm:"uniqueIndex"`
    Password string
}

type Post struct {
    gorm.Model
    UserID  uint
    Content string
    Paid    bool
}

Initialize Database and Migrate Models

Set up the database connection and migrate the models:

go

// main.go
package main

import (
    "pay2post/models"
    "gorm.io/driver/sqlite"
    "gorm.io/gorm"
    "log"
)

func main() {
    db, err := gorm.Open(sqlite.Open("pay2post.db"), &gorm.Config{})
    if err != nil {
        log.Fatal("failed to connect database")
    }

    db.AutoMigrate(&models.User{}, &models.Post{})
}

Set Up Router and Handlers

Use Gin to handle HTTP requests and set up routes for user registration, login, and post CRUD operations:

go

// main.go
package main

import (
    "net/http"
    "pay2post/models"
    "github.com/gin-gonic/gin"
    "gorm.io/driver/sqlite"
    "gorm.io/gorm"
    "log"
)

var db *gorm.DB

func initDB() {
    var err error
    db, err = gorm.Open(sqlite.Open("pay2post.db"), &gorm.Config{})
    if err != nil {
        log.Fatal("failed to connect database")
    }

    db.AutoMigrate(&models.User{}, &models.Post{})
}

func main() {
    initDB()

    r := gin.Default()

    r.POST("/register", register)
    r.POST("/login", login)
    r.POST("/posts", createPost)
    r.GET("/posts", getPosts)
    r.PUT("/posts/:id", updatePost)
    r.DELETE("/posts/:id", deletePost)

    r.Run(":8080")
}

func register(c *gin.Context) {
    // Handle user registration
}

func login(c *gin.Context) {
    // Handle user login
}

func createPost(c *gin.Context) {
    // Handle creating a post
}

func getPosts(c *gin.Context) {
    // Handle retrieving posts
}

func updatePost(c *gin.Context) {
    // Handle updating a post
}

func deletePost(c *gin.Context) {
    // Handle deleting a post
}

Implement Handlers

Add the logic for each handler function to interact with the database and handle HTTP requests.

Create Frontend with HTMX

Set up basic HTML templates and use HTMX to make dynamic requests to the backend:

html

    <!-- templates/index.html -->
    <!DOCTYPE html>
    <html>
    <head>
        <title>Pay2Post</title>
        <script src="https://unpkg.com/htmx.org@1.3.3"></script>
    </head>
    <body>
        <h1>Pay2Post</h1>
        <form hx-post="/register" hx-target="#message">
            <input type="text" name="username" placeholder="Username">
            <input type="password" name="password" placeholder="Password">
            <button type="submit">Register</button>
        </form>
        <div id="message"></div>
    </body>
    </html>

This single issue covers initializing a simple CRUD application, including setting up the project, creating database models, setting up the router and handlers, and integrating a basic frontend with HTMX. describe simple github issue

Implement payment before posting is allowed (stripe payment processing) ChatGPT Issue: Implement Payment Before Posting is Allowed (Stripe Payment Processing) Description

Implement a payment processing system using Stripe to ensure users must pay before they can create a post. This feature will enforce the paywall functionality of the "pay2post" app, ensuring that all posts are paid for before being published. Steps

Set Up Stripe Account
    Create a Stripe account and obtain API keys.
    Add the Stripe keys to your environment variables or configuration file.

Install Stripe Package
    Install the Stripe package for Go:

    sh

go get github.com/stripe/stripe-go/v72

Update Database Model

Add a Paid field to the Post model to track payment status:

go

type Post struct {
    gorm.Model
    UserID  uint
    Content string
    Paid    bool
}

Create Payment Endpoint

Add an endpoint to handle payment processing with Stripe:

go

func paymentHandler(c *gin.Context) {
    var input struct {
        Token string `json:"token"`
        PostID uint  `json:"post_id"`
    }

    if err := c.ShouldBindJSON(&input); err != nil {
        c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()})
        return
    }

    // Set your secret key. Remember to switch to your live secret key in production!
    // See your keys here: https://dashboard.stripe.com/apikeys
    stripe.Key = "sk_test_YOUR_SECRET_KEY"

    params := &stripe.ChargeParams{
        Amount:   stripe.Int64(500), // Amount in cents
        Currency: stripe.String(string(stripe.CurrencyUSD)),
        Description: stripe.String("Pay2Post charge"),
    }
    params.SetSource(input.Token)

    _, err := charge.New(params)

    if err != nil {
        c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()})
        return
    }

    // Mark the post as paid
    var post models.Post
    if err := db.First(&post, input.PostID).Error; err != nil {
        c.JSON(http.StatusNotFound, gin.H{"error": "Post not found"})
        return
    }

    post.Paid = true
    db.Save(&post)

    c.JSON(http.StatusOK, gin.H{"message": "Payment successful and post updated"})
}

Update Post Creation Logic

Ensure that posts can only be created if they are paid for:

go

func createPost(c *gin.Context) {
    var post models.Post
    if err := c.ShouldBindJSON(&post); err != nil {
        c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()})
        return
    }

    post.Paid = false // Initially set as unpaid

    db.Create(&post)
    c.JSON(http.StatusOK, post)
}

Frontend Integration with HTMX

Update the frontend to include payment processing with Stripe before submitting a post:

html

    <!-- templates/post.html -->
    <!DOCTYPE html>
    <html>
    <head>
        <title>Create Post</title>
        <script src="https://js.stripe.com/v3/"></script>
        <script src="https://unpkg.com/htmx.org@1.3.3"></script>
    </head>
    <body>
        <h1>Create a Post</h1>
        <form id="post-form" hx-post="/posts" hx-trigger="submit" hx-target="#message" onsubmit="handlePayment(event)">
            <textarea name="content" placeholder="Your post content..."></textarea>
            <button type="submit">Create Post</button>
        </form>
        <div id="message"></div>

        <script>
            function handlePayment(event) {
                event.preventDefault();
                var stripe = Stripe('pk_test_YOUR_PUBLIC_KEY');

                stripe.createToken('bank_account').then(function(result) {
                    if (result.error) {
                        // Inform the user if there was an error
                        var errorElement = document.getElementById('message');
                        errorElement.textContent = result.error.message;
                    } else {
                        // Send the token to your server
                        fetch('/pay', {
                            method: 'POST',
                            headers: {
                                'Content-Type': 'application/json'
                            },
                            body: JSON.stringify({
                                token: result.token.id,
                                post_id: postID // Replace with the actual post ID
                            })
                        }).then(function(response) {
                            return response.json();
                        }).then(function(data) {
                            var messageElement = document.getElementById('message');
                            if (data.error) {
                                messageElement.textContent = data.error;
                            } else {
                                messageElement.textContent = 'Payment successful and post updated';
                            }
                        });
                    }
                });
            }
        </script>
    </body>
    </html>
