# Backend Setup

Welcome to Backend Setup!

To setup up Algebra Protocol Backend please follow these instructions:

#### 1. Create .env file using .env.example

Basically for local start up you can just copy the `.env.example` as it is

**For production you should change .env**:

1. set BACKEND\_SETTINGS\_MODE to `production`
2. set HTTP\_TEMPLATE\_DIR to `/etc/nginx/templates/ssl`
3. change all passwords to secure
4. change variables with host, ports, etc. as required

#### 2 Place SSL certificates to the ./docker/nginx/ssl dir

**Files have to be named exactly as in `./docker/nginx/templates/ssl/[template]`**

#### 3 Start the project

```
docker compose -f [docker-compose_file] up --build -d
```

For local development you should use `docker-compose.local.yml` and for production - `docker-compose.yml` (or leave file argument empty)

#### 4 Run some commands inside the Django container

Firstly connect to the container with Django. \[container] is equal to either `dev-backend` or `backend`

```
docker compose -f [docker-compose_file] exec [container] bash
```

Then run this inside the container

```
python manage.py makemigrations
```

After the migrations are created you have to apply them

```
python manage.py migrate
```

Then run this command to collect static files for nginx to be able to serve them

```
python manage.py collectstatic
```

Create a superuser to be able to access admin site

```
python manage.py createsuperuser
```

#### 5 Add network with subhraphs

1. Go to the `[HOST]:[PORT]/admin` (if you started a local version it should be `localhost/admin`)
2. Login with the credentials that you used in the previous step
3. Go to the *Networks* tab
4. Click *Add Network*
5. Enter the links to 3 subgraphs
6. Click *Save*

### Additional info

**All the amounts are displayed as *****MATIC***** but are not converted into Matic exactly. This is just a name to the native tokens (since we deployed to the Polygon)**

#### Update tasks

Default settings are:

1. Pools APR are calculated every 1 minute
2. Farmings APR are calculated evey 1 minute

To change the schedule:

1. Go to admin site
2. Go to *Periodic tasks* tab
3. Choose interested task
4. Change *Interval Schedule* in the *Schedule* section
5. If there is no required interval setting you can add it with `+` button near it
