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.

`Deep dive` really suits this course. Every video has at least one new thing to learn

[seydinaoumarsamabaly]

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

[alfredoa]

Impressive!!! By far, the best video of the ManyToMany relations in Django!!! Thank you very much.

[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?

[Pedro_Nora]

Thank you, guy! This is a video that I will watch many times. It has a lot of good information and clear explanations!

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.

[Septumsempra]

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

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