בשרת עשיתי כמה שינויים:

1: recipes.js: פתי פונקצית עדכון זו: router.put('/', recipeMiddleware, (req, res) => { const { title, description, ingredients, instructions } = req.body; const recipeId = req.header('recipe-id'); const db = JSON.parse(fs.readFileSync(dbPath)); const recipe = db.recipes.find(recipe => recipe.id === Number(recipeId));

if (!recipe) {
    return res.status(404).json({ message: "Recipe not found" });
}

if (recipe.authorId !== req.header('user-id')) {
    return res.status(403).json({ message: "Unauthorized" });
}

recipe.title = title;
recipe.description = description;
recipe.ingredients = ingredients;
recipe.instructions = instructions;

fs.writeFileSync(dbPath, JSON.stringify(db, null, 2));

res.json({ recipe });

});

export default router;

2:הוספתי קובץ recipeMiddleware import fs from 'fs'; import path from 'path'; import { fileURLToPath } from 'url';

const __filename = fileURLToPath(import.meta.url); const __dirname = path.dirname(__filename);

export default (req, res, next) => { const recipeId = req.header('recipe-id'); const userId = req.header('user-id'); const db = JSON.parse(fs.readFileSync(path.join(__dirname, '../db/db.json')));

const recipe = db.recipes.find(recipe => recipe.id == recipeId);

if (!recipe) {
    return res.status(404).json({ message: "Recipe not found" });
}

if (recipe.authorId !== userId) {
    return res.status(403).json({ message: "Unauthorized" });
}

req.recipe = recipe; 
next();

};

תודה רבה!!!
