# Step 1: Import models to work with

# Step 2: Create a new address for the employee and save it to the database
e1_address = Address(street_number=123, street_name="Burnel St", city="WINNIPEG", province="MANITOBA", postal_code="R3G2B3")

# Step 3: Create a set of phone numbers for the employee and save them to the database

# Step 4: Create an employee with an address but no phone numbers associated with it and save to the database
# Notice: Before we can associate the ManyToMany relationships we need the record to exist in both the Employee table
#         as well as the PhoneNumber table hence why we save this record before creating the associations

# Step 5: Associate one or more phone numbers to this employee
# Notice: We don't have to save our changes as this is done automatically
