How can I print query set element in Django Template?
I have this code in my template file {{markets|getSpiderItem:spider.id}} Mysql has market_timezone and market_location and it connects to another table with spider_id so I filtered as follow: @register.filter def getSpiderItem(datas, spider_id): return datas.filter(spider=spider_id) I am getting this output: <QuerySet [{'market_timezone': 'Turkey', 'market_location': 'Nigde'}]> I want to print this QuerySet item on Django Template separately.

Django oscar custom benefits does not work
I am building a commercial app using Django and Django-oscar and I am trying to create a custom benefit. I have read Oscar's documentation here and I have also found this relative question in Stack Overflow. I have forked Oscar's offer app and created a benefits.py file where I want to put my custom benefit. I also have change the INSTALLED_APPS setting to include my offer app and not Oscar's default. The problem is that Oscar's doesn't see the benefits.py file no matter what I try. At first I thought that something is wrong with my custom Benefit Class but I tried using Oscar's example and that didn't work either. Then I wrote a piece of code designed to fail (for example a variable which had never been assigned a value to) but it didn't so I am thinking that the file is never accessed.

Incorrect padding. Django with Google Chrome
I asked the question yesterday, but removed it, because it seems I gave too few information and explained the question poorly. But it is kind of solved, but solutions relate to different problems. I just implemented ideas towards this particular problem and I would like to share it, so it might help to somebody out there. So the problem I bumped into is: My site is based on the Django app, when I use Google Chrome it interpret it as (as I understand) 32 bit, meanwhile it is 64 bit (I'm not sure if I'm giving here right description of the problem, but general idea is that) and Google Chrome fails and gives following message: Incorrect padding What I have done to fix the problem. The solution based on: https://gist.github.com/perrygeo/ee7c65bb1541ff6ac770 So I went into: /usr/local/lib/python3.8/base64.py Function name is b64decode, it is on the line 87. It looks like: def b64decode(s, altchars=None, validate=False): """Decode the Base64 encoded bytes-like object or ASCII string s. Optional altchars must be a bytes-like object or ASCII string of length 2 which specifies the alternative alphabet used instead of the '+' and '/' characters.
