Django

Django is a Python web framework for pages, forms, database records and an internal admin site. You can put a customer booking page and staff review in the same project.

Can Django show the booking page and let staff see saved records?

Django can route a booking address to a view, the Python code that decides what response to send. It can display a customer form and store the result. Django’s admin can give authorized staff a separate view of the saved records.

For a first test project, add a simple page with two repair times and one reservation record. Use the admin to inspect the test data after saving. Design the customer’s booking screen around their task and limit the admin to staff who need it.

What should Django check before it confirms a booking?

Validate the form, decide whether the account may book and check that the time is still open. For the simple exercise where one slot can have one reservation, make the database enforce that rule too.

Django’s sign-in and permissions tools help you identify a user. You still decide which bookings that user can read or change. Test staff and customer access separately in the private copy.

  1. Start with a disposable database
    The first Django tutorial uses SQLite locally. Use a separate test file and made-up times. Check the connection before you create any records.
  2. Describe what gets saved
    Define a model for the reservation and apply its migration, the change that prepares the database structure. Give the sample slot a uniqueness rule.
  3. Try one time from two test sessions
    The first request should save a record. The second should leave one record and show that the time is taken. Keep the storage rule even if the screen hides occupied times.

What do you need beyond Django’s local server?

Run Django with a production Python server using a supported deployment interface. Its local development server is for building and debugging. Configure a database with storage that persists beyond a deploy.

Django documents WSGI and ASGI, two ways a Python server connects to the app. Check the option your host supports and the app needs. Plan where styles and uploaded files are served, which settings are private and how staff reach the admin.

Use the production database type in a private test environment before trusting a schema change. Try the same booking after an app restart. Verify you can restore a test backup as well as start the server.

What should you copy before moving a Django app?

Keep the code, the database migration files, private deployment settings and separate backups of records and uploads. Django’s framework code is distributed under a three-clause BSD license. Hosting and storage have their own costs.

A new host can run the code while pointing to an empty database. Open a saved test booking after moving the copy. Check that files and access still work, then test your rollback or restore steps before a live switch.
