Django ManyToManyFields and Through-Models for many-to-many relationships

In this video, we'll look at many-to-many relations in Django. We'll see how to add a ManyToManyField on a Django model, and how to use that field to query for related objects with the ManyRelatedManger and functions such as add(), remove(), all(), set() and clear().
We'll also look at junction tables in the database, created for many-to-many relationships, and will see how Django creates these implicitly, and how we can explicitly add extra data to these tables via through models.

Man thank you, this video clarified my doubt in M2M in django

[@bugbytes3923]

Great to hear, thanks for sharing!

[@treborsol]

Thank you. This was the best overview of the manytomany relation options in Django I have seen so far. Perhaps in a next version you can elaborate on the 'related_name' option and how to use that?

[@bugbytes3923]

Thanks a lot! I'll try and elaborate on related name in future, too.

[@seydinaoumarsamabaly1806]

Just aww, I really can say that I've well understood the M2M concept with this one 🙌🏾. Thank you mate !

Thank you!

[@user-xu7jz4li7e]

@@bugbytes3923 Can you please do a follow-up video and expand on how the ManyToManyFields and the extra fields in the Through-Models can be implemented in Forms and Views? Thank you and have a great weekend!

[@aV5d9nlUBQ9]

Thanks, man! A great video that helped me a lot

[@bugbytes3923]

Thanks a lot !

[@khunjohn1054]

As usual great content. One thing is in the admin panel if you are using inlines, that the model require the related_name..through as the end as in "model = Restaurant.staff.through" if you want to list all staff members under each restaurant in a stacked or tabular inline. This will also display the through table fields. Pretty nifty.

[@bugbytes3923]

Thank you, and nice suggestion there - I should have added it!

please record a course about deep dive in view
and please record a course to customizing admin panel template and add some function to admin panel

[@bugbytes3923]

Thanks, will look into those!

[@Septumsempra8818]

In your next HTMX x Alpine.js video could you cover passing data between htmx and Alpine components. Eg. How do I change an HTMX request based on x-data state?
I saw the "htmx.process()" method, but It's not so clear.
Keep up the great work

[@bugbytes3923]

Great suggestion, I'll add that to the list, thank you!

[@rakeshmali1727]

Hey, great video.
Just one question, at 17:40, can't we just add another `staffs = ManyToManyField(Staff)` in Restaurant model as well?
