The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare git@github.com:usi-systems/easytrace.git

# Based on https://medium.com/@adriennedomingus/soft-deletion-in-django-e4882581c340
# There’s one other thing that might be interesting to point out about the implementation of the soft-deletion: the unique together constraint. 
# If you have a model with a unique together rule for fields ‘a’ and ‘b’, when an entry with the values ‘a=1’ and ‘b=2’ is soft-deleted, another one could not be created with the same values for those fields. So the ‘deleted_at’ has to be included on the constraint.
