in conclusion
ForeignKey
As a foreign key, django associates the id of the Repositories class with the project_name field by default. You cannot write the specific field of project_name directly. Project_name is an object and cannot be queried directly.
project_name__name Double offline to check the specific field content in the Repositories table.
