How
Do I write form.save in async
Anonymous
are field and attribute are the same thing in serializer

are field and attribute are the same thing in serializer
No....
field in general is the *type* of serializer...
attribute is the additional options / properties that the serializer can take, such as null, unique, etc.

Hello everyone
I want to create MicroService Project
We have a gateway service that is supposed to receive CRUD methods and return a response with django rest framwork
And we have a service users that performs the CRUD operation using django gRPC framework in the database
Now I want to connect these two services with gRPC and I don't know how
Thank you for your guidance

def validate(self, attrs) what is atrrs here
attrs are the attriutes that you would pass to that method
Anonymous
in the case validate method attrs is the data we passed to the serializer?
Anonymous
its predefined argument
The Inspired
yes
Anonymous
thanks
The Inspired
which field's data you want to validate
The Inspired
that field would be passed to the serializer
Anonymous
I think it's not in our hands to pass the field its takes all fields i have two field emails and pass e.g. OrderedDict([('email', 'pla@gmail.com'), ('password', 'pla')])
The Inspired
are you using Serializer or ModelSerializer?
Anonymous
serializer only
The Inspired
ah.. then in that case, you probably will have to manually pass the fields
The Inspired
and write the logic for validating only one field
Anonymous
def validate(self, attrs):
try:
user = User.objects.get(email=attrs.get('email'))
except User.DoesNotExist:
user = None
Anonymous
no i did not need to pass the field
Anonymous
ah.. then in that case, you probably will have to manually pass the fields
am I missing something
The Inspired
huh?
The Inspired
wait...
The Inspired
is this validation of your model or your serializer?

1.10 seriously? Please start upgrading.
And.. to be honoust.. with only “this” information anything can be the issue or solution.
What Python version. What PostgreSQL, what OS, what hardware, how big is your project (how many models, how many migrations are already available) …..
Koen de
application
How does (or can) that application call your image upload API?
It is going to send the image as binary or base64 or URL?

There is no best or worst way.
How is the image “available” in your frontend? Please provide as much information as possible so we can help

def uploadImage(request):
import json
print(request.data["invite_id"])
image = json.loads(request.FILES.get['image'])
invite_id = json.loads(request.data['invite_id'])
ivite_image = inviteMarried_request.objects.get(id=invite_id)
ivite_image.image =image
ivite_image.save()
return Response('Image was uploaded')
Hamza
def uploadImage(request):
import json
print(request.data["invite_id"])
image = json.loads(request.FILES.get['image'])
invite_id = json.loads(request.data['invite_id'])
ivite_image = inviteMarried_request.objects.get(id=invite_id)
ivite_image.image =image
ivite_image.save()
return Response('Image was uploaded')
I used this , but when I test it with postman I face this error
Morteza
def uploadImage(request):
import json
print(request.data["invite_id"])
image = json.loads(request.FILES.get['image'])
invite_id = json.loads(request.data['invite_id'])
ivite_image = inviteMarried_request.objects.get(id=invite_id)
ivite_image.image =image
ivite_image.save()
return Response('Image was uploaded')
so you must send the image as form data with postman
Hamza
"detail": "JSON parse error - 'utf-8' codec can't decode byte 0xff in position 265: invalid start byte"
Morteza
You shouldn't use json.loads for image just get it directly
Hamza
i will try it now
Hamza
Same proplem
Koen de
You can help yourself by understanding what you upload;
just before “import json” set;
import pdb
pdb.set_trace()
Then check what’s inside “request”
Hamza
def uploadImage(request):
image = request.FILES.get['image']
invite_id = request.data['invite_id'])
invite_image = inviteMarried_request.objects.get(id=invite_id)
invite_image.image =image
invite_image.save()
return Response('Image was uploaded')
Hamza
i try this
Hamza
Koen de
Just “request”. (Without the “”)
Then you will see what request is all about.
You can also see what’s inside “request.FILES”
Hamza
Ok thank you
Hamza
It returns this
Hamza
With request.data
Hamza
rest_framework.exceptions.ParseError: JSON parse error - 'utf-8' codec can't decode byte 0xff in position 265: invalid start byte
Koen de
What should I put in this terminal
This pdb (Python DeBugger) is pretty handy. Just like the “dir()” method. See
https://docs.python.org/3/library/pdb.html
https://docs.python.org/3/library/functions.html#dir
Koen de
rest_framework.exceptions.ParseError: JSON parse error - 'utf-8' codec can't decode byte 0xff in position 265: invalid start byte
Okay , and just “request”?
The error suggests you are trying to read JSON , but are not sending JSON.
Can you check the networkpanel of your browser too, to verify what you are actually sending to the API?

Does “def uploadImage” have any decorators? And/or how does your urls.py look like.
Is the method “uploadImage” inside a ViewSet or just a standalone method?

rest_framework.exceptions.ParseError: JSON parse error - 'utf-8' codec can't decode byte 0xff in position 265: invalid start byte

Inside the view file
Urls.py I think hasn't any proplem there
Koen de
And the networkpanel in your browser as I asked?
Koen de
I don't understand 🥺
Can you check the networkpanel in your browser to see what data you are posting to the server? The networkpanel in Chrome/Firefox is in the Developer tools (mostly with key F12)

Both can be found in the documentation;
For the first question, check Django Signals ; https://docs.djangoproject.com/en/4.1/topics/signals/
For the second see Form Validation; https://docs.djangoproject.com/en/4.1/ref/forms/validation/

Or maybe I am not understanding the “alert” correctly; if it is an alert to the user who submits the form, see Form Validation too

serializer
then why are you invoking the model inside your validation?
serializers will only the incoming data...
once the data is validated, then only the data passes on to thr model.

For working on Django, channels, websockets and so one on python
The book “Two scoops of Django” helped me to start with Django in the first place. There is a Django 3.x edition.
Another good one is “Lightweight Django (o’reilly)”, but it is not really up to date anymore. Same with “Practical Django 2 and Channels 2 (apress)”
For Python, not really for beginners, but “Fluent Python (o’reilly)” is pretty good too.
