Thank bro...
Francis
How do I get a list of the fields only
Francis
Yeah
Francis
I dnt need the 'model' and the 'pk'
Francis
just the name
Mirco
YourModelClass._meta.get_fields() should work
Francis
Gives an error:
Object of type ManyToOneRel is not JSON serializable
Francis
Yes, I am getting the serialized data
Francis
But in it, there is the ''model'' and ''pk''
Francis
I dnt need them
Francis
That is what I am using bro... (Django Rest Framework) right !?
.
Yes
Francis
I got a query set, and want to return to user...
.
Pass qs to serializer and make many=True
.
For relation fields make your own fields in serializer
.
Or exclude if you don't need them
Francis
But am not able
Francis
let me try that
.
Show code
.
May be we can help
Francis
categories = profile.category.all()
return JsonResponse({'status': '00', "categories": categories}, status=status.HTTP_200_OK)
.
You are not using DRF
.
Use DRF serializer
.
Make CategorySeriliazer class
.
Pass qs to it CategorySerializer(qs, many=True)
.
And return serializer version
.
As CategorySerializer(qs, many=True).data
Francis
Okay... just a min
Francis
"non_field_errors": [
"Expected a list of items but got type \"QuerySet\"."
]
Francis
Same error
Francis
Are you following this ?
This returns:
[
{
"model": "category",
"pk": 2,
"fields": {
"name": "Music"
}
}
]
Francis
But I just wante list of the name
Francis
Maybe I can use a for loop to get the fields.... is it advisable !!?
.
But I just wante list of the name
Bro you can get list of field names. Then convert it to JSON like objects. You can then dump to JSON l. And return string

Hey guys
Before deploying the django project should we change DEBUG=true to DEBUG=false

Hey guys
Before deploying the django project should we change DEBUG=true to DEBUG=false
you have 2 options:
1. Have, at least, 2 separate files to load settings, for dev and prod, in dev you can have DEBUG=True and in prod you should have DEBUG=False
2. Load the value for DEBUG from an environment variable.
My advise: go for option number 1

I had a question.
Abdulboriy Alimov (Abdulboriy Ibn Abdulxay Ibn Sharif Al-Uzbek)
Is it possible to create a application of a website with Django?
Abdulboriy Alimov (Abdulboriy Ibn Abdulxay Ibn Sharif Al-Uzbek)
will Django be enough for that?
Abdulboriy Alimov (Abdulboriy Ibn Abdulxay Ibn Sharif Al-Uzbek)
I mean application for mobile phones .
Sardor
I do not think so, others correct me if I am wrong
Abdulboriy Alimov (Abdulboriy Ibn Abdulxay Ibn Sharif Al-Uzbek)

Sardor

we have a web app in django, but the mobile team developed a mobile app in react native, and we had to write APIs for them.

You can use PWA that make your website appear like app on mobile

Suppose there are 2 fields in table (1) date & (2) production.
