From a database design and management point of view, it is best practice to create tables or in this case classes of linked "choice" data rather than hardcore it as you have show here. Even for simple choice lists....I do realize this is a simplified example, before the next lesson. :) Having choice lists as separate data tables, allows edits and additions (maintainence) by a power user through the admin portal, rather than having to make additions in the code. - I am really enjoying your videos Dennis...Keep up the great work!
Thank god you are doing a tutorial on the latest version of django well on 3.0 but still every other tutorial is 2.x or older. I really like your videos so far and the have helped me a lot. You explain everything really good and your videos are easy to follow. You deffinitely deserve more subscribers. I have a question though, I didn't really understand why there were two of each choice in the STATUS variable and in the CHOICE variable. Not really important but would be nice if you could explain this. Thanks and keep up the good work :)

Watching these from Korea and this tutorials are way better than the tutorials,which need to be paid, in this country. I cannot even believe this lectures are free. And your new django course is way cheap man. we have to pay more than 50 bucks for a django tutorials in this country and it sucks. I really love your channel and vidoes.
I just want to say that your videos have been very helpful. I love the explanations as you go about coding. Thank you very much. In the end, are you going to show how to migrate to a database (e.g. MongoDB)?
Thank you! I’ll integrating a Postgres dB for this series. I’m actually studying mongo + Django integration on the side so maybe I’ll make a one off video about it. Love mongo dB :)
Do these classes represent the objects in the tables or the tables themselves? I notice the fields are static indicating that the Customer class represents the customer table, but wouldn't we need an object whose instances each represent an individual customer (with a non-static name field)?
hm...Dennis, after when I added classes into models.py, when I print command >> python manage.py makemigrations >> in console typed "No changes detected", what could be the reason?
Its either because your changes have already been made and you just need to run migrate or something when wrong when you configured your app and it cant find the models.py file. Make sure you have added the app to INSTALLED_APPS in settings.py
Hi Dennis , Thank you very much for all your efforts , time and making things easy for us . Quick question is it possible to use existing Oracle DB wit Django with no ORM , but use model forms ?
I have done things exactly the same but for some reason when i click the "add customer" button no fields such as name, phone, date show up in the admin interface. I looked up in stackoverflow and rechecked all the possible errors that may have occurred but all the things seem to be fine. I cannot find the problem so it will be a great help if you can tell me what am i doing wrong here. Thanks in advance.
What is the best way to organise models across apps. What are the best practices when you have multiple apps within your project ? E.g. If I want to have a dedicated app for Accounts (which will have models for user profile etc.), and I want to have another app for ManageCustomers and ManageProduct, which model should go where ? BTW, loving the series and learning so much from it ! Thanks a ton for sharing your knowledge
What if I want to rename the class like from Order to another name? I try to do it manually in models.py and then admin.py and migrate but I receive an error. Any ideas please?

I do use it in real world apps and will show it later.

Honestly I have never done that but I'll do some research because I'm curious myself. I'll let you know if I find anything :)
I think that would be possible if you changed your windows timing to the required standard bcz the date Time module will pick your window timing...
why when i created def __str__(self): gives me error
Insted of Tuple we can use list/dict?
class CustomerAdmin(admin.ModelAdmin):
list_display = ['name','phone','email']
list_filter = ['date_created']
search_fields = ['name']
admin.site.register(Customer, CustomerAdmin)
