+# Item Model and Repository Classes Design Recipe
+
+_Copy this recipe template to design and implement Model and Repository classes for a database table._
+
+## 1. Design and create the Table
+
+If the table is already created in the database, you can skip this step.
+
+Otherwise, [follow this recipe to design and create the SQL schema for your table](./single_table_design_recipe_template.md).
+
+*In this template, we'll use an example table `students`*
+
+```
+# EXAMPLE
+
+Table: students
+
+Columns:
+id | name | cohort_name
+```
+
+## 2. Create Test SQL seeds
+
+Your tests will depend on data stored in PostgreSQL to run.
+
+If seed data is provided (or you already created it), you can skip this step.
+
+```sql
+-- EXAMPLE
+-- (file: spec/seeds_{table_name}.sql)
+
+-- Write your SQL seed here. 
+DROP TABLE IF EXISTS items CASCADE;
+
+CREATE TABLE items (
+  id SERIAL PRIMARY KEY,
+  name text,
+  price numeric,
+  quantity int
+);
+
+DROP TABLE IF EXISTS orders CASCADE;
+-- Create the second table.
+CREATE TABLE orders (
+  id SERIAL PRIMARY KEY,
+  customer_name text,
+  date date
+);
+
+
+DROP TABLE IF EXISTS items_orders CASCADE;
+-- Create the join table.
+CREATE TABLE items_orders (
+  item_id int,
+  order_id int,
+  constraint fk_post foreign key(item_id) references items(id) on delete cascade,
+  constraint fk_tag foreign key(order_id) references orders(id) on delete cascade,
+  PRIMARY KEY (item_id, order_id)
+);
+
+TRUNCATE TABLE items RESTART IDENTITY CASCADE;
+TRUNCATE TABLE orders RESTART IDENTITY CASCADE;
+TRUNCATE TABLE items_orders RESTART IDENTITY CASCADE;
+
+
+INSERT INTO items (name, price, quantity) VALUES ('Eggs', '2.99', '10');
+INSERT INTO items (name, price, quantity) VALUES ('Coffee', '5.99', '5');
+INSERT INTO items (name, price, quantity) VALUES ('Bread', '3.99', '15');
+INSERT INTO items (name, price, quantity) VALUES ('Orange Juice', '2.99', '10');
+-- New post inserted with id 3
+
+INSERT INTO orders (customer_name, date) VALUES ('John Key', 'Jan-08-2023');
+INSERT INTO orders (customer_name, date) VALUES ('Sally Smith', 'Jan-09-2023');
+INSERT INTO orders (customer_name, date) VALUES ('Eddie Man', 'Jan-09-2023');
+INSERT INTO orders (customer_name, date) VALUES ('Sam Baker', 'Jan-09-2023');
+-- New tag inserted with id 5
+
+INSERT INTO items_orders (item_id, order_id) VALUES
+(1, 1), 
+(1, 2),
+(2, 2),
+(1, 3),
+(3, 3),
+(4, 4);
+
+ALTER TABLE items_orders ADD FOREIGN KEY (item_id) REFERENCES items(id);
+ALTER TABLE items_orders ADD FOREIGN KEY (order_id) REFERENCES orders(id);
+```
+
+Run this SQL file on the database to truncate (empty) the table, and insert the seed data. Be mindful of the fact any existing records in the table will be deleted.
+
+```bash
+psql -h 127.0.0.1 your_database_name < seeds_recipes.sql
+```
+
+## 3. Define the class names
+
+Usually, the Model class name will be the capitalised table name (single instead of plural). The same name is then suffixed by `Repository` for the Repository class name.
+
+```ruby
+# EXAMPLE
+# Table name: items
+
+# Model class
+# (in lib/item.rb)
+class Item
+end
+
+# Repository class
+# (in lib/item_repository.rb)
+class ItemRepository
+end
+```
+
+## 4. Implement the Model class
+
+Define the attributes of your Model class. You can usually map the table columns to the attributes of the class, including primary and foreign keys.
+
+```ruby
+# EXAMPLE
+# Table name: items
+
+# Model class
+# (in lib/item.rb)
+
+class Item
+    
+    attr_accessor :id, :name, :price, :quantity
+end
+
+```
+
+*You may choose to test-drive this class, but unless it contains any more logic than the example above, it is probably not needed.*
+
+## 5. Define the Repository Class interface
+
+Your Repository class will need to implement methods for each "read" or "write" operation you'd like to run against the database.
+
+Using comments, define the method signatures (arguments and return value) and what they do - write up the SQL queries that will be used by each method.
+
+```ruby
+
+# Table name: items
+
+# Repository class
+# (in lib/item_repository.rb)
+
+class ItemRepository
+    def all
+        # shows all items
+        sql = 'SELECT id, name, price, quantity FROM items;'
+        result = DatabaseConnection.exec_params(sql, [])
+
+        items = []
+
+        result.each do |record|
+            item = Item.new
+            item.id = record['id']
+            item.name = record['name']
+            item.price = record['price']
+            item.quantity = record['quantity']
+        end
+    end
+
+    def find(id)
+    end
+
+    def create(item)
+        def create(item)
+        sql = 'INSERT INTO items
+                    (name, price, quantity)
+                    VALUES($1, $2, $3);'
+        sql_params = [item.name, item.price, item.quantity]
+
+        DatabaseConnection.exec_params(sql, sql_params)
+
+        return nil
+    end
+
+    def delete(item)
+    end
+
+end
+
+# EXAMPLE
+# Table name: recipe
+
+# Repository class
+# (in lib/recipe_repository.rb)
+
+    def find(id)
+    # SELECT id, name, price, quantity FROM items WHERE id = $1;
+    end
+
+    def create(album)
+        sql = 'INSERT INTO albums
+                    (title, release_year, artist_id)
+                    VALUES($1, $2, $3);'
+        sql_params = [album.title, album.release_year, album.artist_id]
+
+        DatabaseConnection.exec_params(sql, sql_params)
+
+        return nil
+    end
+
+      
+    def delete(id)
+      sql = 'DELETE FROM accounts WHERE id = $1;'
+      sql_params = [id]
+
+      DatabaseConnection.exec_params(sql, sql_params)
+
+      return nil
+    end
+```
+
+## 6. Write Test Examples
+
+Write Ruby code that defines the expected behaviour of the Repository class, following your design from the table written in step 5.
+
+These examples will later be encoded as RSpec tests.
+
+```ruby
+
+  # 1
+        it 'shows all items' do
+            repo = ItemRepository.new
+
+            items = repo.all
+            expect(items.length).to eq 4
+            expect(items.first.id).to eq '1'
+            expect(items.first.name).to eq 'Eggs'
+        end
+  # 2
+        it 'returns a single item' do
+            repo = ItemRepository.new
+
+            item = repo.find(1)
+            expect(item.name).to eq 'Eggs'
+            expect(item.price).to eq '2.99'
+        end
+  # 3
+        it 'returns another item' do
+            repo = ItemRepository.new
+
+            item = repo.find(2)
+            expect(item.name).to eq 'Coffee'
+            expect(item.price).to eq '5.99'
+        end
+
+  # 4
+        it 'creates and item' do
+            repo = ItemRepository.new
+
+            item = Item.new
+            item.name = 'Bananas'
+            item.price = '1.99'
+            item.quantity = '10'
+            repo.create(item)
+
+            expect(repo.all.length).to eq 5
+        end
+
+  # 5
+        it 'deletes an item' do
+            repo = ItemRepository.new
+            id_to_delete = 1
+            repo.delete(id_to_delete)
+
+            expect(repo.all.length).to eq 3 
+        end
+
+
+Encode this example as a test.
+
+## 7. Reload the SQL seeds before each test run
+
+Running the SQL code present in the seed file will empty the table and re-insert the seed data.
+
+This is so you get a fresh table contents every time you run the test suite.
+
+```ruby
+# EXAMPLE
+
+# file: spec/recipe_repository_spec.rb
+
+def reset_recipes_table
+  seed_sql = File.read('spec/seeds_recipes.sql')
+  connection = PG.connect({ host: '127.0.0.1', dbname: 'recipes_directory_test' })
+  connection.exec(seed_sql)
+end
+
+describe RecipeRepository do
+  before(:each) do 
+    reset_recipes_table
+  end
+
+  # (your tests will go here).
+end
+```
+
+## 8. Test-drive and implement the Repository class behaviour
+
+_After each test you write, follow the test-driving process of red, green, refactor to implement the behaviour._

+
+Columns:
+id | name | cohort_name
+```
+
+## 2. Create Test SQL seeds
+
+Your tests will depend on data stored in PostgreSQL to run.
+
+If seed data is provided (or you already created it), you can skip this step.
+
+```sql
+-- EXAMPLE
+-- (file: spec/seeds_{table_name}.sql)
+
+-- Write your SQL seed here. 
+
+DROP TABLE IF EXISTS items CASCADE;
+
+CREATE TABLE items (
+  id SERIAL PRIMARY KEY,
+  name text,
+  price numeric,
+  quantity int
+);
+
+DROP TABLE IF EXISTS orders CASCADE;
+-- Create the second table.
+CREATE TABLE orders (
+  id SERIAL PRIMARY KEY,
+  customer_name text,
+  date date
+);
+
+
+DROP TABLE IF EXISTS items_orders CASCADE;
+-- Create the join table.
+CREATE TABLE items_orders (
+  item_id int,
+  order_id int,
+  constraint fk_post foreign key(item_id) references items(id) on delete cascade,
+  constraint fk_tag foreign key(order_id) references orders(id) on delete cascade,
+  PRIMARY KEY (item_id, order_id)
+);
+
+TRUNCATE TABLE items RESTART IDENTITY CASCADE;
+TRUNCATE TABLE orders RESTART IDENTITY CASCADE;
+TRUNCATE TABLE items_orders RESTART IDENTITY CASCADE;
+
+
+INSERT INTO items (name, price, quantity) VALUES ('Eggs', '2.99', '10');
+INSERT INTO items (name, price, quantity) VALUES ('Coffee', '5.99', '5');
+INSERT INTO items (name, price, quantity) VALUES ('Bread', '3.99', '15');
+INSERT INTO items (name, price, quantity) VALUES ('Orange Juice', '2.99', '10');
+-- New post inserted with id 3
+
+INSERT INTO orders (customer_name, date) VALUES ('John Key', 'Jan-08-2023');
+INSERT INTO orders (customer_name, date) VALUES ('Sally Smith', 'Jan-09-2023');
+INSERT INTO orders (customer_name, date) VALUES ('Eddie Man', 'Jan-09-2023');
+INSERT INTO orders (customer_name, date) VALUES ('Sam Baker', 'Jan-09-2023');
+-- New tag inserted with id 5
+
+INSERT INTO items_orders (item_id, order_id) VALUES
+(1, 1), 
+(1, 2),
+(2, 2),
+(1, 3),
+(3, 3),
+(4, 4);
+
+ALTER TABLE items_orders ADD FOREIGN KEY (item_id) REFERENCES items(id);
+ALTER TABLE items_orders ADD FOREIGN KEY (order_id) REFERENCES orders(id);
+```
+
+Run this SQL file on the database to truncate (empty) the table, and insert the seed data. Be mindful of the fact any existing records in the table will be deleted.
+
+```bash
+psql -h 127.0.0.1 your_database_name < seeds_recipes.sql
+```
+
+## 3. Define the class names
+
+Usually, the Model class name will be the capitalised table name (single instead of plural). The same name is then suffixed by `Repository` for the Repository class name.
+
+```ruby
+# EXAMPLE
+# Table name: orders
+
+# Model class
+# (in lib/order.rb)
+class Order
+end
+
+# Repository class
+# (in lib/order_repository.rb)
+class OrderRepository
+end
+```
+
+## 4. Implement the Model class
+
+Define the attributes of your Model class. You can usually map the table columns to the attributes of the class, including primary and foreign keys.
+
+```ruby
+# EXAMPLE
+# Table name: iorder
+
+# Model class
+# (in lib/order.rb)
+
+class Order
+    
+    attr_accessor :id, :customer_name, :date
+end
+
+```
+
+*You may choose to test-drive this class, but unless it contains any more logic than the example above, it is probably not needed.*
+
+## 5. Define the Repository Class interface
+
+Your Repository class will need to implement methods for each "read" or "write" operation you'd like to run against the database.
+
+Using comments, define the method signatures (arguments and return value) and what they do - write up the SQL queries that will be used by each method.
+
+```ruby
+
+# Table name: orders
+
+# Repository class
+# (in lib/order_repository.rb)
+
+class orderRepository
+    def all
+        # shows all orders
+        sql = 'SELECT id, customer_name, date FROM orders;'
+        result = DatabaseConnection.exec_params(sql, [])
+
+        orders = []
+
+        result.each do |record|
+            order = Order.new
+            order.id = record['id']
+            order.customer_name = record['customer_name']
+            order.date = record['date']
+
+            orders << order
+        end
+    end
+
+    def find(id)
+    end
+
+    def create(item)
+        def create(item)
+        sql = 'INSERT INTO items
+                    (name, price, quantity)
+                    VALUES($1, $2, $3);'
+        sql_params = [item.name, item.price, item.quantity]
+
+        DatabaseConnection.exec_params(sql, sql_params)
+
+        return nil
+    end
+
+    def delete(item)
+    # 'DELETE FROM items
+    #                 WHERE id = $1;'
+    end
+
+end
+
+```
+
+## 6. Write Test Examples
+
+Write Ruby code that defines the expected behaviour of the Repository class, following your design from the table written in step 5.
+
+These examples will later be encoded as RSpec tests.
+
+```ruby
+
+  # 1
+        it 'shows all items' do
+            repo = ItemRepository.new
+
+            items = repo.all
+            expect(items.length).to eq 4
+            expect(items.first.id).to eq '1'
+            expect(items.first.name).to eq 'Eggs'
+        end
+  # 2
+        it 'returns a single item' do
+            repo = ItemRepository.new
+
+            item = repo.find(1)
+            expect(item.name).to eq 'Eggs'
+            expect(item.price).to eq '2.99'
+        end
+  # 3
+        it 'returns another item' do
+            repo = ItemRepository.new
+
+            item = repo.find(2)
+            expect(item.name).to eq 'Coffee'
+            expect(item.price).to eq '5.99'
+        end
+
+  # 4
+        it 'creates and item' do
+            repo = ItemRepository.new
+
+            item = Item.new
+            item.name = 'Bananas'
+            item.price = '1.99'
+            item.quantity = '10'
+            repo.create(item)
+
+            expect(repo.all.length).to eq 5
+        end
+
+  # 5
+        it 'deletes an item' do
+            repo = ItemRepository.new
+            id_to_delete = 1
+            repo.delete(id_to_delete)
+
+            expect(repo.all.length).to eq 3 
+        end
+
+
+Encode this example as a test.
+
+## 7. Reload the SQL seeds before each test run
+
+Running the SQL code present in the seed file will empty the table and re-insert the seed data.
+
+This is so you get a fresh table contents every time you run the test suite.
+
+```ruby
+# EXAMPLE
+
+# file: spec/recipe_repository_spec.rb
+
+def reset_recipes_table
+  seed_sql = File.read('spec/seeds_recipes.sql')
+  connection = PG.connect({ host: '127.0.0.1', dbname: 'recipes_directory_test' })
+  connection.exec(seed_sql)
+end
+
+describe RecipeRepository do
+  before(:each) do 
+    reset_recipes_table
+  end
+
+  # (your tests will go here).
+end
+```
+
+## 8. Test-drive and implement the Repository class behaviour
+
+_After each test you write, follow the test-driving process of red, green, refactor to implement the behaviour._

+# Two Tables (Many-to-Many) Design Recipe Template
+
+_Copy this recipe template to design and create two related database tables having a Many-to-Many relationship._
+
+## 1. Extract nouns from the user stories or specification
+
+```
+As a shop manager
+So I can know which items I have in stock
+I want to keep a list of my shop items with their name and unit price.
+
+As a shop manager
+So I can know which items I have in stock
+I want to know which quantity (a number) I have for each item.
+
+As a shop manager
+So I can manage items
+I want to be able to create a new item.
+
+As a shop manager
+So I can know which orders were made
+I want to keep a list of orders with their customer name.
+
+As a shop manager
+So I can know which orders were made
+I want to assign each order to their corresponding item.
+
+As a shop manager
+So I can know which orders were made
+I want to know on which date an order was placed. 
+
+As a shop manager
+So I can manage orders
+I want to be able to create a new order.
+```
+items, name, price, item quantity (number), orders, customer name, date placed (for order)
+```
+
+## 2. Infer the Table Name and Columns
+
+Put the different nouns in this table. Replace the example with your own nouns.
+
+| Record                | Properties          |
+| --------------------- | ------------------  |
+| items                 | name, price, quanitity
+| orders                | customer_name, date
+
+1. Name of the first table (always plural): `items` 
+
+    Column names: `customer_name`, `price`, `quantity`
+
+2. Name of the second table (always plural): `customer_orders` 
+
+    Column names: `name`, `date`
+
+## 3. Decide the column types.
+
+[Here's a full documentation of PostgreSQL data types](https://www.postgresql.org/docs/current/datatype.html).
+
+Most of the time, you'll need either `text`, `int`, `bigint`, `numeric`, or `boolean`. If you're in doubt, do some research or ask your peers.
+
+Remember to **always** have the primary key `id` as a first column. Its type will always be `SERIAL`.
+
+```
+# EXAMPLE:
+
+Table: items
+id: SERIAL
+name: text
+price: numeric
+quantity: int
+
+Table: orders
+id: SERIAL
+customer_name: text
+date: date
+```
+
+## 4. Design the Many-to-Many relationship
+
+Make sure you can answer YES to these two questions:
+
+1. Can one [TABLE ONE] have many [TABLE TWO]? (Yes/No)
+2. Can one [TABLE TWO] have many [TABLE ONE]? (Yes/No)
+
+```
+# EXAMPLE
+
+1. Can one item have many orders? YES
+2. Can one order have many items? YES
+```
+
+_If you would answer "No" to one of these questions, you'll probably have to implement a One-to-Many relationship, which is simpler. Use the relevant design recipe in that case._
+
+## 5. Design the Join Table
+
+The join table usually contains two columns, which are two foreign keys, each one linking to a record in the two other tables.
+
+The naming convention is `table1_table2`.
+
+```
+# EXAMPLE
+
+Join table for tables: items and orders
+Join table name: items_orders
+Columns: item_id, order_id
+```
+
+## 4. Write the SQL.
+
+```sql
+-- EXAMPLE
+-- file: items_orders.sql
+
+-- Replace the table name, columm names and types.
+
+-- Create the first table.
+CREATE TABLE items (
+  id SERIAL PRIMARY KEY,
+  name text,
+  price numeric,
+  quantity int
+);
+
+-- Create the second table.
+CREATE TABLE orders (
+  id SERIAL PRIMARY KEY,
+  customer_name text,
+  date date
+);
+
+-- Create the join table.
+CREATE TABLE items_orders (
+  item_id int,
+  order_id int,
+  constraint fk_post foreign key(item_id) references items(id) on delete cascade,
+  constraint fk_tag foreign key(order_id) references orders(id) on delete cascade,
+  PRIMARY KEY (item_id, order_id)
+);
+
+```
+
+## 5. Create the tables.
+
+```bash
+psql -h 127.0.0.1 database_name < posts_tags.sql
+```
