Hi! I have a problem... I have model Company, which has two fields owner and general_balance these has a one-to-one relationship with Owner and GeneralBalance model... Each model has its own serializer, but CompanySerializer must include the serializer of Owner and GeneralBalance, so far so good, the problem appears when I try to send post, put request because I cannot modify nested objects... Does someone have any idea to solve this problem?
hi , serializers are read-only by default . but you can make function based on your needs and handle different methods in that functions .function names are important :
def create(self, validated_data): # 'create' handle post
def update(...): # 'update' handle put
and ...
so you should handle them in the serializer thats where to start

Hi every one. I’m studying django channels for the first time. I have a question
How can I transform this in to Class-based Views
from django.shortcuts import render
def room(request, room_name):
return render(request, 'chat/room.html', {
'room_name': room_name
})

Hi guys
A quick question....
Is it safe to save sensitive data in session?!
Irrfan

So what should I use to store temp data?!
For example store verification code that send to user....

Django is python
You can do whatever u prefer

For example, I have data in the database and I want to do math operations on it, can I get that?

Yes, get the data from database and do whatever you want
You can do math operations directly with ORM queries

Hi everyone. I'm new with Django and having some trouble with models and PostgreSQL data types, in my database I have a field of a composed data type, that need to be mapped to varchar, but to do this, my model need add a cast function in this field. Ex: the query "select field from test_table", need to be "select field::varchar from test_table" or "select cast(field as varchar) from test_table".
Ps: this explicit type cast need to work with insert and update commands too
Anyone has a hint, how I could but this explicit cast into a Django model?
Thanks!!!

Thanks to all, i think that https://docs.djangoproject.com/en/3.1/howto/custom-model-fields/ it what I need :D

How to write this query in django.:
select col1, col2, col3, col4, col5 where col2=xval group by col5
Problem: to do 'group by' we use .values(col5) but this results in selecting only col5 in output . I need all columns in output.
Doing values(col1, col2...col5) selects all columns but results in 'group by' on all columns.
Thank You

Hi All,
I am new to django and trying to use login using authenticate method in one of my view function login
My model contains user_name, user_email, password.
When i try to pass user_email and password in authenticate, it returns None. Using postman to hit thr function.
My register function works perfectly and i can see my user details in sqllite.
For authenticate, is it mandatory to use username as parameter?
Thanks in advance

In your custom user model set USERNAME_FIELD='user_email', for more info check the custom authentication from django docs
