Project from the FH-Bielefeld in Germany

For this you have to install Django on your enviroment.

First install a Postgresql-Database on your own Computer.

sudo apt-get update
sudo apt-get install python-pip python-dev libpq-dev postgresql postgresql-contrib

Change to the User who was created by the commands before (postgres):

sudo su - postgres

Log into Postgres :

psql

Now you can create your Database (!dont forget the semikolon after each operation!):

CREATE DATABASE project;

Create a User:

CREATE USER myUser WITH PASSWORD 'MyPassword';

Make some Setups for speeding up operations:

ALTER ROLE myprojectuser SET client_encoding TO 'utf8';
ALTER ROLE myprojectuser SET default_transaction_isolation TO 'read committed';
ALTER ROLE myprojectuser SET timezone TO 'UTC';

Now the User needs access to your database:

GRANT ALL PRIVILEGES ON DATABASE myproject TO myprojectuser;

Back to the user's shell:

\q
exit

For the REST SERVICE DJANGO-RESTFRAMEWORK you need to install:

sudo pip install djangorestframework markdown django-filter

The django REST framework, markdown support for browsable API and filtering support

Add 'rest_framework' to your INSTALLED_APPS setting in settings.py.

INSTALLED_APPS = (
    ...
    'rest_framework',
)

If you're intending to use the browsable API you'll probably also want to add REST framework's login and logout views. Add the following to your root urls.py file.

urlpatterns = [
    ...
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]

More Information on Django REST Framework: http://www.django-rest-framework.org/

To avoid crossite-skripting Conflicts install Django CORS Headers

pip install django-cors-headers

make some changes in settings.py:

add to installed apps

INSTALLED_APPS = (
    ...
    'corsheaders',
    ...
)

add to middleware

MIDDLEWARE = [  # Or MIDDLEWARE_CLASSES on Django < 1.10
    ...
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.common.CommonMiddleware',
    ...
]

for now we allow all crossitescriptings

CORS_ORIGIN_ALLOW_ALL = True

To use Bootstrap install the following

pip install django-bootstrap3

make some changes in settings.py:

add to installed apps

INSTALLED_APPS = (
    ...
    'bootstrap3',
    ...
)

More Information on Django bootstrap3: https://django-bootstrap3.readthedocs.io

After that, you can start coding with Django.

The Setup for the server you can see in YourProject/YourProject/settings.py. In our case: dba16-web/wohlfuehlprojekt/settings.py.

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'project',
        'USER': 'myUser',
        'PASSWORD': 'myPassword',
        'HOST': 'localhost',
        'PORT': '',
    }
}

To start your server. Open another terminal and navigate to /etc/init.d/ and start your database with "./postgresql start". With the command "psql -l" you can see your running databases.

Apply the migrations to your database. Go into your Project (the "dba16-web" folder). And set up the initial databse structure:

python manage.py makemigrations
python manage.py migrate

Create an administrative account:

python manage.py createsuperuser

Select a username,emailadress and password. Test youre Server:

python manage.py runserver 127.0.0.1:8000

Visit your server in your web browser:

http://server_domain_or_IP:8000
maybe: localhost:8000

How to fix the "bad magic number" error

Run from the highest directory of your project:

find . -name '*.pyc' -delete
