Creating the DNB_SERVICE_TOKEN for data-hub-api

For data-hub-api to connect to dnb-service, it must be provided with a token which is set inside the data-hub-api .env file under DNB_SERVICE_TOKEN.

Local development token

1. Create a user in dnb-service.
2. Log into the admin with this user.
3. Go to tokens.
4. Add a token.
5. Select your user and save.
6. Copy your token key into the data-hub-api DNB_SERVICE_TOKEN environment variable.

UAT, dev, staging and prod token

Using the current api user

1. There is a default user set for these environments with the username: api-user@digital.trade.gov.uk
2. You can find this users token in the Django Admin and selecting the token model or by accessing the django shell for the environment you require.
3. For getting the token in the Django shell run the following:

   from rest_framework.authtoken.models import Token
   from django.contrib.auth import get_user_model
   
   User = get_user_model()
   user = User.objects.get(email='api-user@digital.trade.gov.uk')
   
   token = Token.objects.get(user=user)
   print(token.key)
   

4. Copy the token printed above into data-hub-api DNB_SERVICE_TOKEN environment variable.

Creating a new api user

1. Access the Django shell for the environment you want to create a user for.
2. Run the following, you can change the email if required:

   from rest_framework.authtoken.models import Token
   from django.contrib.auth import get_user_model
   
   User = get_user_model()
   
   user = User.objects.create(email='api-user@digital.trade.gov.uk')
   token = Token.objects.create(user=user)
   
   print(token.key)
   

3. Copy the token printed above into data-hub-api DNB_SERVICE_TOKEN environment variable.

DIT staff-sso integration

The admin section is protected by the DIT's internal SSO application. To run a local development environment with admin access you can either request a set of UAT SSO credentials from the webops team, or check out the staff-sso github repository and run the application locally. See https://www.github.com/uktrade/staff-sso for more details.

Swagger Documentation

Once the app is running, you will be able to visit http://localhost:9000/api/swagger/ to see documentation for the endpoints.
