Sure, you can use the session key of Django as a foreign key by creating a new model that inherits from the
django.contrib.sessions.models.Sessionmodel and adding a foreign key to theusermodel.The following code shows how to do this:
Python
This code creates a new model called
SessionUserthat inherits from thedjango.contrib.sessions.models.Sessionmodel. Thesession_keyfield is a foreign key to theSessionmodel, and theuserfield is a foreign key to theauth.Usermodel.To use the
session_keyfield as a foreign key, you would need to create a new model that inherits from theSessionUsermodel. For example, the following code shows how to create a new model calledOrderthat inherits from theSessionUsermodel:Python
This code creates a new model called
Orderthat inherits from theSessionUsermodel. Theorder_numberfield is a string field that stores the order number, and thetotal_pricefield is a decimal field that stores the total price of the order.You can then use the
session_keyfield to query theOrdermodel. For example, the following code shows how to query theOrdermodel for all orders that were placed by the user with the session key1234567890:Python
This code will return a list of all orders that were placed by the user with the session key
1234567890.
