Spa Management

About

Website for spa manager and employees.

Prerequisites

Install docker-compose and docker

Setup

On Linux

1. Make this script executable

chmod u+x script.bash

2. Build and set up docker containers

./script.bash

3. IP Addresses

Web app is hosted at 0.0.0.0:8000, PostgreSQL GUI is hosted at 0.0.0.0:8080.

4. Credentials

PgAdmin4:

Database:

  • hostname is db
  • name is myapp
  • admin login is django
  • admin password is django

5. Create root user

To create root user u have to:

Run docker ps and copy CONTAINER ID from web app container

sudo docker ps

Enter the container

docker exec -it <your_id> bash

Inside migrate databases

python manage.py migrate

Create superuser

python manage.py createsuperuser

In WSL

Check if you have WSL2 in order to run docker. Remember about installing docker and docker-compose.

  1. Get your ip address: ip addr show eth0 | grep inet | awk '{ print $2; }' | sed 's//.*$//'
  2. Add it to settings.py ALLOWED_HOSTS
  3. App: <your_address>:8000, postgreSQL: <your_address>:8080

Additionaly, you might need to run the commands from script.bash manually on command line.

Usage

Entering the container

Build and set up docker containers

./script.bash

Run docker ps and copy CONTAINER ID from web app container

sudo docker ps

Enter the container

docker exec -it <your_id> bash

Making migrations

Making default migrations

To migrate default migrations just run this command:

python manage.py migrate

Reversing migrations

It is possible to reverse migrations and remove contents from database.
To do so run:

python manage.py migrate <app_name> zero

For example:

python manage.py migrate SpaApp zero

Making a new migration

After you modified a model in models.py you need to make a migration.
To do so, inside the container specify app you would like to make migrations for

python manage.py makemigrations <app_name>

For example:

python manage.py makemigrations SpaApp

And then migrate

python manage.py migrate

Making a new empty migration

It is also possible to create a new empty migration like so:

python manage.py makemigrations --empty <app_name> --name <migration_name> 

For example:

python manage.py makemigrations --empty SpaApp --name seed_database

Spa User lazy reference

If you get the following error:

ValueError: The field admin.LogEntry.user was declared with a lazy reference to 'SpaApp.user', but app 'SpaApp' doesn't provide model 'user'.

Go to settings.py and in INSTALLED_APPS list comment the line with 'django.contrib.admin', so the list should look like:

INSTALLED_APPS = [
    # 'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    "django_bootstrap5",
    'SpaApp',
]

then go to the urls.py and comment the admin/ path, this will look like:

urlpatterns = [
                  path('', include('SpaApp.urls')),
                  # path('admin/', admin.site.urls),
              ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)  # For product images

After both lines are commented make migrations:

python manage.py migrate 

And then uncomment those lines.

Missing Spa User

In case of this error:

psycopg2.errors.UndefinedTable: relation "SpaApp_user" does not exist
spamanagement-web-1 | LINE 1: ...pp_user"."date_joined", "SpaApp_user"."type" FROM "SpaApp_us...

you need to open forms.py and comment these lines:

# def _get_employee_list() -> list[tuple[int, str]]:
#     """return list of emplyee"""
#     users = user_model.objects.all()
#     return [(user.id, user.username) for user in users]
# 

class AppointmentForm(forms.ModelForm):
    date = forms.DateField(widget=forms.DateInput(attrs={'type': 'date'}))
    time = forms.TimeField(widget=forms.TimeInput(attrs={'type': 'time'}))
    description = forms.CharField(widget=forms.Textarea, required=False)

    # employee = forms.ChoiceField(choices=_get_employee_list(),
    #                           widget=forms.Select(attrs={'class': 'form-control'}))

    class Meta:
        model = Appointment
        fields = ["name", "description", "date", "time"]

With those lines commented now you should be able to migrate.
After migration uncomment those lines back.
