# Django REST Framework Contacts API Template
## Description
This is a single model full CRUD API for contacts using Python and Django.
> This is an **api only**. I would suggest consuming this API using React as a _separate server_ by using [create-react-app](https://reactjs.org/docs/create-a-new-react-app.html).
### Contacts Properties:
|Property | Type | Default |
|---|---|---|
| id | integer | assigned by db |
| name | string | n/a |
| age | integer | n/a |
### Contacts Routes:
|Endpoint | Action |
|---|---|
| `/api/contacts` | GET (Index) |
| `/api/contacts/:id` | GET (Show) |
| `/api/contacts` | POST |
| `/api/contacts/:id` | DELETE |
| `/api/contacts/:id` | PUT |
## System Requirements
- Python 3
- pipenv
### Installation
If you don't have either of the above, please install them.
<details><summary>Python3 Installation</summary><p>
#### Python Installation
1. Check what python version you have on your computer by running: `python -V`
1. If you're not on a version of Python that is 3 or greater, install python 3 with homebrew:
- `brew install python3`
- Note: in order to use this installed python3, you will have to use `python3` whenever running a python command
</p></details>
<details><summary>pipenv Installation</summary><p>
#### pipenv Installation
To build your app, we're going to be building a virtual environment. In order to manage our dependencies and our virtual environment, we're going to use [pipenv](https://pipenv.pypa.io/en/latest/).
1. Check if you have pipenv by running: `pipenv --version`
1. If you do not have it, install it with homebrew:
- `brew install pipenv`
</p></details>

## Get Set Up Locally
### On your Browser
1. Fork this repository to your account
### In your Terminal
1. Clone **your fork** of the repo onto your computer anywhere that is not a git repo
1. `cd` into the repo
1. Touch a `.env` into the root of your project and add a SECRET_KEY value. See the .env.sample file for an example
1. Install all the required packages by running: `pipenv install`
1. Activate the virtual environment by running: `pipenv shell`
- NOTE: To exit the shell gracefully whenever you're done working, use `exit`
1. Create the `django_contacts` psql database and user by running the following while in the pipenv shell: `psql -U postgres -f settings.sql`
- You can find the database name and username/password inside the settings.sql file
1. Apply the migrations by running the following while in the pipenv shell: `python3 manage.py migrate`
1. Make a superuser for your app, this will allow you to work directly with your database on the browser without having to use Postman
- In the pipenv shell, run `python3 manage.py createsuperuser` and follow the instructions
1. Start the Django server by running the following inside the pipenv shell: `python3 manage.py runserver`
### On your Browser
1. Go to `localhost:8000/api/contacts`. You should see the Django REST Framework interface like so:

1. Click the `Log In` on the top right corner and use the username/password you created when making the superuser
1. You should now be able to add / delete / edit / read contacts directly from your browser
---
## Making Changes
### Updating / Creating Models
1. If you make any changes to the `contacts_api/models.py` file, you will need to make and run a migration to apply the changes. You can do so by using the following commands while _inside the pipenv shell_
1. Make the migration: `python3 manage.py makemigrations`
1. Apply the migration: `python3 manage.py migrate`
---
## Set Up for Heroku Deployment
### In Terminal
1. Create a heroku app from the root of your project folder, run: `heroku create`
- The above command will randomly generate a name for you, if you want to name your app something specific run: `heroku create urlNameYouWantHere`
### In your Code Editor
1. Copy the heroku url that was created (without the `https://`), go to your `django_rest_api/settings.py` and add it into the `ALLOWED_HOSTS`
- e.g.
![](https://imgur.com/AVlB8kK.png)
### On the Browser
1. Go to your heroku dashboard for the heroku project you just created
1. Click on Configure Add-Ons
1. Search for Heroku Postgres and add it
1. Go to the Settings, Reveal Config Vars, add a config var for SECRET_KEY and anything else you have in your .env file
### In Terminal
1. `pipenv lock` to ensure your pipfile.lock is up to date
1. `git add -A`
1. `git commit -m "heroku deployment"`
1. `git push heroku master`
1. Once it builds successfully, run `heroku run bash`
1. While in heroku bash, apply the migrations to the heroku project by running: `python manage.py migrate`
1. Still in heroku bash, create a superuser for the heroku project by running `python manage.py createsuperuser` and follow the prompts
- To exit heroku bash, run `exit`
### In Browser
1. After the migrations finish, you should now be able to open the heroku app in your browser to see the Django REST interface!
- Don't forget to go to `/api/contacts`
1. Remember that your heroku database is separate from your local database, so there should not be any data on the first load.
- You can add data by logging in with the heroku superuser you created
1. You can now use this deployed version as your backend API

## Resources
Django and Rest are both fairly opinionated frameworks meaning there are right ways to do things. If you plan on making many changes to this template, I would recommend looking at their documentation:
- [Django Documentation](https://docs.djangoproject.com/en/3.1/)
- Particular pages you may want to look at:
- [Making Queries (Django's built in ORM)](https://docs.djangoproject.com/en/3.1/topics/db/queries/#)

- [Migrations](https://docs.djangoproject.com/en/2.0/topics/migrations/)
- [URLs Config](https://docs.djangoproject.com/en/3.1/topics/http/urls/)
- [Djagno REST Framework Documentation](https://www.django-rest-framework.org/) (Click on the API Guide dropdown on the nav bar to see their documentation for specific things)
