To integrate with different database OR New SQLite database:

Integrate Manually:

1. Django provides default setting for SQLite3. If you decide to use a different database, please refer to this documentation for configuration details.

   Copy

   
   DATABASES = {
       "default": {
           "ENGINE": "django.db.backends.sqlite3",
           "NAME": BASE_DIR / "db.sqlite3",
       }
   }
   

2. To make migration of the database, run the following command in the terminal:
   Copy

   python manage.py migrate

3. To access the Django admin panel, you need to create a superuser account. If you want to know how to create a super user, refer to this Documentation.

   Copy

   python manage.py createsuperuser
   

4. When the server starts, you can access the Django admin panel by simply adding '/admin' to the base URL, resulting in http://127.0.0.1:8000/admin.

5. Once you are Logged in navigate to "GROUP" section, and create 2 groups.

   1. Group admin with all permission.
   
   2. Group client with only Transaction view permission.

      Note: This permission is specific to the Transaction app, playing a crucial role in displaying the Transaction app for new clients. You also have the flexibility to create and assign custom permissions to the 'client' group as needed.

      Tip: If you want to learn how to use permission in Materialize, please refer to the Authentication.
      For more detailed information on permissions, please refer to the official Django documentation.
      

6. After creating the group mentioned earlier, navigate to the Users section in the admin panel, and assign the admin group to the superuser.

   Info : When a user is created through the authentication process, they will be automatically assigned to the client group.
7. To seed the database with fake transactions for the CRUD app, run the following command.
Copy

python manage.py loaddata transactions-list.json

If you prefer not to use seed data, you can remove the 'fixtures' folder from the 'transactions' app.

Integrate with datadump.json:

Follow the instructions outlined in steps 1 to 2 under the Integrate Manually section. Subsequently, execute the provided command to import data into a different database or a new SQLite database.

python manage.py loaddata datadump.json

NOTE: Materialize already provides datadump.json file under full-version/datadump.json. Though if you want to export your data, use command python3 manage.py dumpdata > datadump.json to Dump data from SQLite.

Integrate with PostgresSQL:

Migrating a Django application from SQLite to PostgreSQL involves a few steps. Here's a general guide to help you with the process:

1. Install PostgreSQL: Make sure PostgreSQL is installed on your machine or server. You can install it using a package manager like Homebrew on macOS or apt on Ubuntu. Alternatively, you can download and install it from the official PostgreSQL website.
2. Install psycopg2: Update your Django project's requirements to include the psycopg2 package, which is a PostgreSQL adapter for Python. Install it using:
   Copy

   pip install psycopg2

3. Update DATABASES Settings: Update your Django project's config/settings.py file to use PostgreSQL. Modify the DATABASES setting:
   Copy

   DATABASES = {
             'default': {
                 'ENGINE': 'django.db.backends.postgresql',
                 'NAME': 'your_db_name',
                 'USER': 'your_db_user',
                 'PASSWORD': 'your_db_password',
                 'HOST': 'localhost',
                 'PORT': '5432',
             }
         }
                 

   Replace your_db_name, your_db_user, and your_db_password with your PostgreSQL database name, user, and password.

4. Run the following Django management commands to create the PostgreSQL database schema and migrate data:
   Copy

   python manage.py migrate

5. Execute the provided command to import data into a different database or a new SQLite database.
   Heds up!: This approach is recommended only when working with a completely new database. If you attempt to load the datadump.json file into an existing database, it may overwrite your current data.
   Copy

   python manage.py loaddata datadump.json

   NOTE: Materialize already provides datadump.json file under full-version/datadump.json.
