## Local Repository Setup(Linux)

This guide walks you through setting up the repository locally, installing dependencies. Follow the steps carefully to get your development environment up and running.

**Pre-requisite:** 
- Install [Poetry][poetry] for dependency management

- Install Pgadmin4 for database management

### Database Setup

Follow these steps to set up the database locally:

1. **Install PostgreSQL:**
Download and install PostgreSQL on your system : [Download PostgreSQL for Linux ](https://www.postgresql.org/download/linux/ubuntu/)


2. **Start PostgreSQL Service:**
```bash
sudo service postgresql start
```


3. **Check PostgreSQL Status:**
Ensure the service is running properly:
```bash
sudo service postgresql status
```


4. **Get Your Local IP Address:**
Copy the IP address to configure your connection:
```bash
hostname -I
```


5. **Create the Database:**
Use **pgAdmin 4** or the command line to create your database.


6. **Run Migrations with Alembic:**
Export the database URL and apply migrations:
```bash
export DB_URL="postgresql://<username>:<password>@<your_ip>:5432/<your_database>"
```


- **Note:** Replace the placeholders with your actual database credentials.

7. **Run the migrations:**
```bash

poetry run alembic upgrade head
```



### Steps to setup the repository locally

1. **Fork & Clone the Repository:**
```bash
git clone https://github.com/openclimatefix/pv-site-datamodel.git
```


2. **Navigate to the Repository:**
```bash
cd pv-site-datamodel
```

3. **Install Dependencies:**
```bash
poetry install
```


4. **Activate Virtual Environment:**
```bash
source .venv/bin/activate
```


5. **Set Database URL:**

Replace the placeholder with your actual database connection string.
```bash
export DB_URL="postgresql://<username>:<password>@<your_ip>:5432/<your_database>"
```


6. **Make Code Changes:**

Modify the necessary code files as needed.


7. **Format the Code:**
```bash
make format
```


8. **Lint the Code:**
```bash
make lint
```


---


## Running the tests

Run the following command to execute the test suite:

```bash
    make test
```

## Multiple Clients

We have the ability to have these different scenarios

1. one user - can add or view one site
2. one user, can add or view multiple sites
3. Two users (for example from the sample company), want to look at one site
4. Two users, wanting to look at multiple sites (could be added by another user). Any user from site group can add a site.
5. OCF user want to see everything (admin)

### Solution

```mermaid
  graph TD;
      User-- N:1 -->SiteGroup;
      SiteGroup-- N:N -->Site;
```

- One `user` is in one `sitegroup`. Each site group can have multiple users.
- Each `sitegroup` contains multiple `sites`. One `site` can be in multiple `sitegroups`

### 1. one user - one site

```mermaid
  graph TD;
      A(User=Alice)-->B(SiteGroup=Alice1);
      B --> C(Site);
```

### 2. one user - two sites

```mermaid
  graph TD;
      A(User=Alice)-->B(SiteGroup=Alice1);
      B --> C1(Site1);
B --> C2(Site2);
```

### 3. Two users - one site

```mermaid
  graph TD;
      A1(User=Alice)-->B(SiteGroup);
A2(User=Bob)-->B(SiteGroup);
      B --> C1(Site1);
```

### 4. Two users - two site

```mermaid
  graph TD;
      A1(User=Alice)-->B(SiteGroup);
A2(User=Bob)-->B(SiteGroup);
      B --> C1(Site1);
B --> C2(Site2);
```

### 5. OCF can see everything

```mermaid
  graph TD;
      A1(User=Alice)-->B(SiteGroup1);
A2(User=Bob)-->B(SiteGroup1);
A3(User=OCF)-->B2(SiteGroup2);
      B --> C1(Site1);
B --> C2(Site2);
      B2 --> C1(Site1);
B2 --> C2(Site2);
B2 --> C3(Site3);
```
