YumBot

Description

A web application providing customized recipes created by the YumBot

How to run

First, get a Spoonacular API key by visiting this site. Select the basic plan. Then, in the Rapid API dashboard, click "Add New App" on the left navigation bar. Name the application "YumBot". YumBot should not show up in your "My Apps" section on the left navigation bar. Then, select YumBot and in the dropdown menu, click on "Security". You should be able to see your API key. Copy this key and set it as an environment variable on your machine by typing this command in a terminal window

export SPOONACULAR_API_KEY=<your-key>

Then, ensure that you have Python version 2.6+ installed on your machine. To confirm, open a terminal and run the following command to ensure that python is installed and it is the correct version.

python --version

Then,

1. Clone this repository

    git clone https://github.com/SrutiG/YumBot.git

2. Navigate to the flask_boilerplate folder

    cd YumBot

3. Install the necessary requirements

    pip install --user -r requirements.txt

4. Make sure that the run.py file has executable permissions

    chmod +x run.py

5. Run this command

    ./run.py

6. Navigate to the URL 127.0.0.1:8095 in your browser

A page should appear saying Hello World.

Create the Database

This application currently uses a SQLite database generated in the app folder. In order to create the database, run the following commands.

1. Give executable permissions to the db_create.py and db_migrate.py files

    chmod +x db_create.py && chmod +x db_migrate.py

2. Run db_create.py to create the database

    ./db_create.py

3. Run db_migrate.py to create the migrations based on the current schema

    ./db_migrate.py

Populate the database

The file modify_db.py can be used to add/remove recipes from the database and run algorithms. Make sure it has executable permissions by running the following command

chmod +x modify_db.py

Then, run it with your chosen arguments.

./modify_db.py [args]

These are the available arguments

argument name	type	default value	possible values	description
action	string	add	add, remove, matrix, pca, kmeans, add_calc, remove_calc	add: add recipes to the database. Use numrecipes arg to set number of recipes to add. Default is 10 remove: remove recipes from the database. Use numrecipes flag to set number of recipes to remove. matrix: recreate the co-occurrence matrix based on current recipes in the database. This is done automatically after adding recipes. pca: calculate pca coordinates based on current co-occurrence matrix. kmeans: calculate kmeans clusters based on pca coordinates. add_calc: add recipes to database, calculate pca coordinates and kmeans coordinates. Use numrecipes to set number of recipes to add. remove_calc: remove recipes from database. calculate pca coordinates and kmeans coordinates. Use numrecipes to set number of recipes to remove.
numrecipes	int	10	any integer >= 0	number of recipes to add or remove from the database
components	int	24	any integer between 0 and 24	number of PCA components
clusters	int	35	any positive integer	number of k-means clusters

Other files

Add new endpoints

Create new endpoints for the application in the file app/views.py

Edit HTML Templates

Currently there is a layout.html file in app/templates which contains the topbar, headers, and links to the css and js files in app/static/css/index.css and app/static/js/index.js. Create new templates which extend layout.html.

Modify Algorithms

Co-occurrence matrix: app/cooccur.py K-Means: app/kmeans.py PCA: app/pca.py

Edit YumBot logic

The YumBot class is located in app/yumbot.py. It is used to check if ingredients are compatible and create new recipes.

Add to the Database Schema

The database schema is located in app/models.py. After making changes to this schema, make sure you create new migrations by running the command

./db_migrate.py

Change the host and port

By default, this application runs on 127.0.0.1:8095. Change the default host and port in run.py or run it on a different host and port using the --host and --port flags. For example,

./run.py --host <your-host> --port <your-port>
