There is ofcourse a bit of mess with it in django admin, but you should not rely on it.

Luis

In django templates are representation layer.

I just liked what I see on the admin

Luis

Ok I think I got it

You should not rely on __str__ in your app.

Alex

At least if it's (your app) for someone other than you.

Luis

Another thing, not related: if I want to create more User fields

Luis

should this be done by relating another model to the User or by creating a custom User model?

Luis

or, how would you go if you wanted to create a user comments model

Alex

It depends on your database design

Luis

It depends on your database design

I want each user to post one comment per product but they can post comments in many products.

Luis

How do I identify the User?

Luis

sorry for my bad question

Luis

where can I read more about example django database designs?

Alex

I want each user to post one comment per product but they can post comments in many products.

> I want each user to post one comment per product Sounds more like a review, than a comment. So there are 3 entities - Users, Products and Reviews. User may have many reviews, but a review has only single user. Therefore we make: class Review: user = ForeignKey(User) A review can be dedicated only for single product. So we add there one more fk - to a product. I'm ommiting here fields like text, rate and other.

I see

We also can add it unique_togther constraint to the Review model so a user could not review the same product multiple times. https://docs.djangoproject.com/en/3.1/ref/models/options/#unique-together like unique_together = [['user', 'product']]

Thanks, I'll have to make some experiments on a simple model to see what I get and learn.

Luis

But you helped me a lot.

U r welcome, kiddo.

Database design is a separate topic in software development and has nothing to do with django. Here's a book I learned about database design myself. "Beginning Database Design" by Clare Churcher

I have a Client model where I need relationship to multiple users from User Model. I am using OneToMany relationship field. I can able to select only one user in Admin Panel from drop down list. I want to select multiple users instead of one. Should I have to use ManyToMany relationship or there is anyway to select multiple users in dropdown list in admin panel.

what did you mean?

In this case you are using ur own custom class. The built in User object is inherited from django.contrib.auth.models library

So how can I use this class to generate a token using signals as it showing some errors

Wait you are not overriding the Django user

Hi there! Speaking about DRF, I found myself being throttled on localhost after I tried to test anon throttling settings. Tried to cache.clear(), clear LockMemCache, restart server, cleared browser caches and data. Still being throttled by my own django code. Is it smth like land mine for begginers? I looked at DRF throttling code, they do use default cache to store/check client . What else it can be?
