Try on incognito if color is applied then make a hard refresh on your page

I've tried hard refresh one time by long pressing the refresh button and it updated but again got same issue but now long pressing refresh button doesn't show and empty cache and hard restart

Please check you have configured static settings in settings.py
Yes I've add static directory, the css file is working previously but suddenly i got this issue

I think you should check your css file path in link tag

You mean to say you cannot do hard refresh or is it not working

Yeah it linked correctly, ive completed half off the project with that css file

For keyboard it's ctrl shift r

But adding style on html file itself means, it working

i.e there is only problem in changing color other css properties are working correctly

No all properties like height, width font size everything, Even after commenting whole class on css , the browser showing the previous style

Migrations have nothing to do with CSS... low effort

Okay, i have a kind of hot question.
I have a model with a M2M field.
I have to order that field based of a custom metric.
Like
1- get all the objects of that M2M
2 - calculate a score for each one
3 - order them based on the highest scores
Right now i have a serializer like this
class DealListSerializer(serializers.ModelSerializer):
rank = serializers.SerializerMethodField()
def get_rank(self, obj):
rank = -1
for partners in obj.partners:
if partner.experience > 5:
rank += 10
elif 3 <= partner.experience < 5:
rank += 5
return rank
def get_partners():
self.obj.partners.all().order_by("rank")
How to do this?
I have thought of using annotate but the function i need is complex so idk.
I know using a get_rank function is wrong but i needed to write something.
I would like to use a function to get the score of each object in that M2M and order by it.

I don't see anything "wrong" with how you're doing it, what's the issue you're experiencing?

just order your queryset based on rank?
Sibiselva
ctrl shift r working
When i add style directly in html and make input width to 50px its working but when i add style on css means max-width:50 px only making the input width to 50
George

Rank is an internal calculation not an actual field of my model.

Kinda similar, i ended up doing this.
class BarListSerializer(serializers.ModelSerializer):
def get_partners(self, obj):
partners = self.obj.partners.all()
rank = [0 * len(partners)]
for i, partner in enumerate(partners):
if partner.experience > 5:
rank[i] += 10
elif 3 <= partner.experience < 5:
rank[i] += 5
if (
self.obj.city
and self.obj.city == partner.city
):
rank[i] += 10
return sorted(zip(partners, rank), key=itemgetter(1))
I don't know if it's a valid answer but
() { :;}; echo Nickolas
It might do the job, kinda slow but idk. Seems simple enough
well I guess it's exponential growth depending on the # of partners
() { :;}; echo Nickolas
If you don't need them real time perhaps just schedule a job that calculates it for you with celery?
George
well I guess it's exponential growth depending on the # of partners
yes, i would prefer doing this in a query thing :<
() { :;}; echo Nickolas
and define it as a property on your model
George
This should be cached hmmm
() { :;}; echo Nickolas
This should be cached hmmm
Use something like redis to cache it in?
Schedule celery task every minute that calculates the rank
Dump variable in redis
Fetch every time you need it
Celery task updates redis every minute and gives you an "up-to-date" rank
() { :;}; echo Nickolas
That approach won't make your request slower and you still have cached/semi real-time ranks

You can pass a method to upload_to

Hi everyone
In my Django API view I have couple of loggers, and it's in production, problem is when I make POST request for example by Postman with the api, I can see all request logs and headers in my log file, but there is another company that try to use the same API in our system but I can't see none of their Post requests in logs just the GETs, but when I'm checking Nginx logs I can see that they've sent POST request too.

How can I query like the YouTube/Google does like:
If I type 'mr bounae' it will show all similar including 'mr bean'
With django
Maset
Filter
But I couldn't find something like this one
When I filter by 'mr bounae' it will return only matches 'mr bounae', 'mr bounaeer', 'mr bounae series' like that
And not 'mr bean' or 'mr' or 'bean'
..

Use machine learning things. Natural language processing is best for this requirement
