Hi, I ran into a problem. I have two models inherited from one, the first is public, and the second is created when editing the first, so moderation is organized.

Roman
By using an Update view
So if the method is update , save() will call update ?

No, it will use the update you set into the serializer to know what you wanna update
Mirco
Study better DRF docs and you will find all answers

SomeQuerySet is a Queryset object, returned by sth like Model.objects.filter(pk__gt=10). How to find some element by condition IN SomeQuerySet. I've tried SomeQuerySet.get(...), but in makes another query to database instead of looking up in ready SomeQuerySet.

How can i add fields during runtime in django rest. Problem: In User model there's a field for adding few preferences. By default it should be 3. if user wants, he should be able to add more preferences for the preferences field. How should i approach this ?

u should go with foreign key or many to many relationship make a model of preference and then connect it to user model, with foreign key u can just connect the preference model to user

Instead of doing SomeQuerySet.get(field2=value2) you can do SomeQuerySet.filter(field2=value2) that give you a queryset with just only one 'element' and maybe, more direct SomeQuerySet.filter(field2=value2).first()

I've so simple query, I'm new to django. There a star I want to print for certain number of times. <ul> {% for i in range ( num ) %} 🌟 {% endfor %} And I'm getting an error, such a noob question but please ♥️
Dixit
Thank you much for your replies but ... What do you don't write code in templates ?
Dixit
Is there another way ? 😳
cj
Thank you much for your replies but ... What do you don't write code in templates ?
because templates are used to show final results only, not to deal with logic
Gigil
It's not secure to write logic in template I think
cj
build the list in the views, then show it on the template, yes you can make basic iterations on it too
Dixit
I'm writing functions in views.py and using render method I pass Template names
Dixit
Is it a wrong or inefficient way ? Or am I doing right ?
Gigil
Is it a wrong or inefficient way ? Or am I doing right ?
That's correct. In view create a list and pass it as context hope it fixes
Dixit
Thank you 💕

there's something like this to make your template dumb, view short and Model smart
