How to use order_by query after sliceing a query

You cannot do that.

you should first order by, and then slice it. There is no much logic in ordering (or filter) after slicing

Why do you add an id field if all models already have one?

Instead of the default object value, its easier to identify entries from ID Just thats why !!

Wait, what? entries are identified with a default ID field. By default, Django gives each model the following field: id = models.AutoField(primary_key=True) This is an auto-incrementing primary key.

what i think you mean is that you want to change the string representation of that model... 🧐 in that case you should override the str(self) method

This thing is not working for me, that was the reason I wanted to try the above approach !! AutoField is not creating any id in any of my models.....

It sounds like a bad idea to perform Scrapping using selenium (and selenium is not an scrapping tool btw) in a HTTP request, my recommendation is to have the scraping thing in a different process and run it periodically or asyncronously store results on DB and the check the results in the HTTP reqest

is it impossible to perform scrapping via selenium in HTTP request or it's just not recommended?

You can give us a clue on how to help by being more descriptive. Didn’t load how? Was there an error? What error was displayed? Does it only display pythonanywhere’s default app page?

hello.. How to make a query SELECT ... FROM (SELECT ...) forcibly ?

I mean, what I should use to separate internal "select" from external ? Subquery isn't useful for this...

hello.. How to make a query SELECT ... FROM (SELECT ...) forcibly ?

What exactly you want to do? I mean forget the SQL because you are suing an ORM on django, so what's your desired outcome?

I want something like this: Separator(MyModel.objects.filter(...).annotate(...)).filter(.<by fields created in annotate>.).exclude(.<by fields created in annotate>.)

in objectives I want to filter my queryset by new annotated fields (like status, some summas, etc)

if I do it in standard in simple flat select - it does not work as it should.. It filters first and then calculates balance-on-row. But I need vice versa

I have one issue...from frontend date is coming in string '01/12/2022' in dd-mm-yyyy format but django save it into mm-dd-yyyy format 12/01/2022

I have one issue...from frontend date is coming in string '01/12/2022' in dd-mm-yyyy format but django save it into mm-dd-yyyy format 12/01/2022

You have to parse the date string before saving it

Using the dateutil library: import dateutil.parser date_string = '01/12/2022' date_parsed = dateutil.parser.parse(date_string) # datetime.datetime object YourModel.objects.create(date=date_parsed) Or using the datetime library: import datetime date_string = '01/12/2022' date_parsed = datetime.datetime.strptime(date_string, '%d/%m/%Y') # datetime.datetime object YourModel.objects.create(date=date_parsed)
