### **Installing Django**
___

Before installing Django, you must have Python installed on your machine. 

To install Django, follow the following steps:
1. Create a virtual environment:

It is highly recommended to create a virtual environment before installing Django. 

A virtual environment allows you to isolate your Python environment and avoid conflicts with other Python packages that may be installed on your machine.

To create a virtual environment, open the terminal and navigate to the directory where you want to create the environment. Then type the following command:
```bash
python -m venv myenv
```
This will create a new virtual environment named "myenv".

To activate the virtual environment, type the following command:
```bash
source myenv/bin/activate
```
This will activate the virtual environment and you should see the name of the environment in the terminal prompt.

>Note that to activate your virtual environment on Widows, you will need to run the following code below (See this <a href="https://docs.python.org/3/library/venv.html">link</a> to fully understand the differences between platforms):
```bash
 env/Scripts/activate.bat //In CMD
 env/Scripts/Activate.ps1 //In Powershel
 ```
2. Install Django:

With the virtual environment activated, you can now install Django using pip, the Python package manager. Type the following command:
```bash
pip install Django
```
This will download and install the latest stable version of Django.

3. Verify the installation:

To verify that Django is installed correctly, type the following command in the terminal:
```bash
python -m django --version
```
This should output the version number of Django that you just installed.

Congratulations, you have successfully installed Django on your machine! 
You can now start building web applications using Django.

### **Installing Horilla**
___

For installing the Horilla, follow the following steps:
1. Clone the project repository from GitHub:
```bash
git clone https://github.com/horilla-opensource/horilla.git
```
2. Install the required dependencies using pip:

For installing the python dependencies required for the project, run the following command by going into the project directory.
 ```bash
 pip install -r requirements.txt
 ```
3. Set up the database by running the following commands:
```bash
python manage.py makemigrations
python manage.py migrate
```
4. Create an admin employee account:
```bash
python manage.py createhorillauser
```
>Note: createhorillauser is a similar command to createsuperuser in Django,  which creates an admin user along with a related admin employee into the database.

<br>
Enter the details asked for creating the admin user for the project.
5. Running the project
To run the project locally, execute the following command:

```bash
python manage.py runserver
```
If everything is configured correctly, you should be able to access your Horilla app at http://localhost:8000.

>Note: 
>>If you wish to run the Horilla application to any other port, you can specify the port number after the runserver command.

>>eg: *python  manage.py runserver <port_number>*

>Note: 
>>By default a SQLite database will be setup for the project with demo data already loaded.

>>If you wish to start with a fresh database, remove the db.sqlite3 file from the project directory and run the migrate command followed by the createhorillauser command to start with a fresh database.

>>Or if you wish to change the database, refer the below section.

### **Database Setup**
___

By default an SQLite database will be setup for the project, incase you wish to change the database of your choice, please use the below reference to do the same.

**PostgreSQL**

To setup postgresql database for the project, first you have to install the PostgreSQL and its python package ***psycopg2*** .
1. Install the psycopg2 package using pip. This package is a PostgreSQL database adapter for Python.
```bash
pip install psycopg2
```
2. In the project settings file (settings.py), add the following database settings:
```python
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': '<database_name>',
        'USER': '<database_user>',
        'PASSWORD': '<database_password>',
        'HOST': '<database_host>',
        'PORT': '<database_port>',
    }
}
```
Replace *<database_name>, <database_user>, <database_password>, <database_host>, and <database_port>* with your PostgreSQL database settings.

3. Run migrations to create the necessary database tables.
```bash
python manage.py makemigrations
python manage.py migrate
```

[Django PostgreSQL Database](https://docs.djangoproject.com/en/4.2/ref/databases/#postgresql-notes)

**MySQL**

To configure a MySQL database in Django, follow these steps:
1. Install the ***mysqlclient*** package which will allow Django to interact with MySQL. You can install it using pip:
```bash
pip install mysqlclient
```
2. In the project settings file (settings.py), add the following database settings:
```python
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': '<database_name>',
        'USER': '<database_user>',
        'PASSWORD': '<database_password>',
        'HOST': '<database_host>',
        'PORT': '<database_port>',
    }
}
```
Replace *<database_name>, <database_user>, <database_password>, <database_host>, and <database_port>* with the appropriate values for your MySQL installation.


3. Run migrations to create the necessary database tables.
```bash
python manage.py makemigrations
python manage.py migrate
```
For more details:
[Django MySQL Database](https://docs.djangoproject.com/en/4.2/ref/databases/#mysql-notes)

**MariaDB**

To configure a MariaDB database with Django, you can follow the same steps used for MySQL database configuration as shown above.
For more details:
[Django MariaDB Database](https://docs.djangoproject.com/en/4.2/ref/databases/#mariadb-notes)

**SQLite**

To configure a SQLite database with Django, you can follow these steps:
1. In the project settings file (settings.py), add the following database settings:
```python
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    }
}
```
This will create a SQLite database in your project directory named db.sqlite3.



2. Run migrations to create the necessary database tables.
```bash
python manage.py makemigrations
python manage.py migrate
```
>*Note that SQLite has some limitations compared to other databases, so you may need to consider these limitations if you have a large amount of data or a high level of concurrency in your application.*

[Django SQLite Database](https://docs.djangoproject.com/en/4.2/ref/databases/#sqlite-notes) 

**Oracle**

To configure an Oracle database with Django, you can follow these steps:
1. Install the cx_Oracle package which will allow Django to interact with Oracle. You can install it using pip:
```bash
pip install cx_Oracle
```
2. In the project settings file (settings.py), add the following database settings:
```python
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.oracle',
        'NAME': '<database_name>',
        'USER': '<database_user>',
        'PASSWORD': '<database_password>',
        'HOST': '<database_host>',
        'PORT': '<database_port>',
    }
}
```
Replace *<database_name>, <database_user>, <database_password>, <database_host>, and <database_port>* with the appropriate values for your Oracle installation.


3. Run migrations to create the necessary database tables.
```bash
python manage.py makemigrations
