Why can't I filter object by using UUID as primary key in django??

I'm defining my model and for some fields I've added birthday = models.DateField(name=_("User birthday")) and I get the error TypeError: getattr(): attribute name must be string. What am I doing wrong here ? name can't be translated ? Is Name even needed or is the field variable name is the same as the name passed in the constructor ?

Can somebody share framework, ORM, Auth library and REST API videos??

Improve your question.
Classic viewset will look like:
serializer_class = SomeSerializer
queryset = SomeModels.objects.all
But I need viewset with static data: {'name': 'Alex'}
In simple django framework, it will just:
def somedata(request):
context = {'name': 'Alex'}
return render(request, 'some.html', context)

Try this format Name = 'use...'

I'm using vue js, so I need to send the data
Брат
I can do that in frontend itself, but Im practising with sending the data from backend
Saurav
Ok no issues just return json.dumps(python_dict)
Saurav
From your views
Брат
I mean I can return something only in def function
Saurav
Yes you can try.
Брат
Okay, thank you, I'll take a look to it, I'll let you know if it didn't work
Saurav
Sure.
Saurav
Or simpler you can use return JsonResponse(python_dict)
Saurav
With with your function based view.

how does django work? first the model, then the view, then the url?
Брат
how does django work? first the model, then the view, then the url?
somehow yes, if you use html and css for frontend
Брат
however in case that you use frontend like reactjs, vuejs and etc. you need to add serializers so you could pass the data
Брат
model -> serializers -> views -> url = API
Брат
By the way, Im newbie don't trust me
Saurav
Request-->url.py-->views.py+models.py-->template--> Response
Saurav
In simple way.
Saurav
For better read blogs on request-response cycle in django.

How to display the excel sheet data in the form of table in the web browser using django ?
Anyone have the idea about this , how can we do it
Saurav
# load XLSX workbook
wb = Workbook("workbook.xlsx")
# save workbook as HTML file wb.save("workbook.html")
Dev
Not this way
Dev
Something other than this
Dev
I have an excel file that should be displayed in the form of tables in the webpage not the exact excel sheet but only the data,
And with the help of some html to we should be able to choose the file and submit it ,here the thing is when we submit it,
It should be displayed on the webpage (not the excel sheet itself) but in the form of table
Saurav
Dev
Yes
Saurav
This was the logic for backend.
Saurav
If you want to select a file and wants to convert it to html then you have to create a form for that. After submitting the file you can convert it to html format by using above logic.
Dev
Ok thanks

Second Option is to change emoji to anyother format like string or code format then try to save it.
Rohan

Hey， guys ， how to do 4 table join select in Django？
Are all the tables linked through many to many or foreign key relation?

I have a question. I have django 3.0 and postgres 9.6 and want to annotate a queryset of a model by values from its m2m table. Here is my try:
Petition.objects.filter(incidents__fact_id__isnull=False).annotate(facts=ExpressionWrapper(F('incidents__fact_id'), output_field=ArrayField(IntegerField())))
So Incident has a fk on Petition and Fact. The problem is that the facts annotation gets only a single value from the set, but I need the whole set.
