Admin app
application that Django done to help you to manipulate the model quicker
under airline → urls.py
Admin account need to be created before we use it → How?
Terminal: python manage.py createsuperuser
After creating the admin account:
Go to admin under app and import models
Tell admin app that I would like to manipulate Airport and Flight models
How it works?
go to the admin url
You can edit the table in admin
Also for flight
Customize the web application so that user can view details when you click on the flight — every flight to have its own page
OR
if you use pk ← ignore the name of what it is being called
What if the id is not exist in the table?
Deal with it later
Why flight to airport is not a many-to-many relationship?
1. 1 origin/destination only link to 1 airport (one to one?)
2. 1 airport link to many 1 origin/destination (one to many?)
Why flight to passenger is a many to many relationship?
1. 1 flight could be related to more than 1 passenger (use primary key as reference)
2. 1 passenger could be related to more than 1 flight
reference: https://code.tutsplus.com/articles/sql-for-beginners-part-3-database-relationships--net-8561
Add passengers to the flight
As passengers to flight is a many to many relationship: use function ManyToManyField
Go to admin.py under flight → add the model to admin
if you could add more than 1 options here, it will be at least x to many relationship.
if you want to select more than 1 customers in flight, it will be many to many relationship
Go to view to pass information from passenger
Go to flight.html to include the passenger information
Add in link to go back to index and route
Allow the passengers to book a flight
Whenever you would like to manipulate the database, should be in POST method.
update flight.html
Admin interphase could be customized to do what you want to do
This will change the display of table in admin
You could check documentation for more information: https://docs.djangoproject.com/en/3.0/ref/contrib/admin/
Tutor’s favorite display for many to many relationship:
Users- authentication
Start with creating new app: users
When the app was named as users: user ←attribute already assigned
above function: tell you that the user is authenticated or not
update the login.html and layout.html
Then go to admin to add in users
Further information could be edited here
After logging out admin, try to go to user
then update if I successfully login
useful!!! If there is variable message pass through → show the message
When I login with wrong username:
Now need to edit the page when user successfully login the page:
how to get the user name?
request.user.first_name ← inside django, you have access to the HTTP request ← also the user and first_name
How to logout the user?
Directly applying the logout function with the django built-in function is super helpful
