Thanks Arbaaz, as long as it is useful to someone I will carry on making tutorials regardless of the future prospects 👍

Thank you very much for this video series. It is really the best series on Django ORM.

[@veryacademy]

Glad you enjoy it! Once I get back setup with recording I will improve upon it and add some more

So while making migrations it didn't created a table for base class why??

[@veryacademy]

class Publishable(models.Model): title = models.CharField(...) date = models.DateField(....) class Meta: abstract = True If for example you set the meta to abstract - any other tables using this abstract class will copy title and data to that class - this table Publishable will not be created. A benefit is that it is a way of creating fields that would be replicated in multiple tables - saving you having to write these fields out multiple times

[@manishranjan9982]

For class A it has meta derived from BaseMeta so why don't A is also abstract=True?

[@veryacademy]

Hi, I cant remember what is in the video but - key here is that abstract=True on a model will mean that it is not actually created in the database - all over classes or models connected will just inherit (make a copy of) the fields. If you dont use abstract true all models are created in the database

[@georgesmith3022]

So if I want to have different types of users, each with different fields, for instance Students and Teachers, should I choose a User model and inherit from there? or should I create a different Profile for each and use a onetoone relationship with the user model?

[@veryacademy]

Good question - how about 1 user table and additional tables for students and teachers 1to1

[@kiorepaul6278]

Hi again. Thanks for making such great lecture series. I felt you should have covered queries involving related_name. And are you planning on a series on orm/sql queries optimisation i.e how to minimise number of db queries?

[@dh1ao]

Thanks for all your work. Is there a chance of a video regarding array/lists in ORM Django models besides postgres?

[@veryacademy]

Sure there is - what exactly were you thinking? This could mean many things - array/lists in ORM Django models besides postgres?

[@dh1ao]

@@veryacademy I would like to store an array of Python objects in a sql database other than postgres. For postgres there is a model.array_field. Maybe a json serializer could do a similar job for let's say mysql? Thanks for reading

[@KevinTempelx]

Thank you!!

[@veryacademy]

You're welcome!

[@AhmedTheCoder]

What if I have three types of reports( daily, weekly, monthly) Different fields, they are have common relationship with two models (staff, machines) That have lot of fields, I want to make a relation between these models, can I use inherited models, or foreign keys? Help!

[@pallyweb]

Hi bro, In your tutorials VS Code provides very good IntelliSense . However , I am unable to get much out of VS Code for Django/Python IntelliSense . Kindly help in this regard. Thanks :)

[@sambad8429]

the proxy model part is very incomplete

[@veryacademy]

Thanks Samba, at the time it met the needs of what I needed. I will no doubt come around on this again in the future

[@rezarostami891]
