The best way to do an efficient filter query in django
models.py file I am not so good at this aspect in Django. Please can someone help me? I wish to know if there is a more efficient way for the class method already_voted class Vote(TimeStamped): voter = models.ForeignKey(get_user_model(), verbose_name=_("Vote"), on_delete=models.CASCADE) contester = models.ForeignKey(Contester, verbose_name=_("Contester"), on_delete=models.CASCADE, help_text=("The chosen contester"), related_name="votes") ip_address = models.GenericIPAddressField( _("Voter's IP"), protocol="both", unpack_ipv4=False, default="None", unique=True ) num_vote = models.PositiveIntegerField(_("Vote"), default=0) class Meta: unique_together = ('voter','contester') verbose_name = _("Vote") verbose_name_plural = _("Votes") permissions = ( ("vote_multiple_times", "can vote multiple times"), ) .... .... @classmethod def already_voted(cls, contester_id, voter_id=None, ip_addr=None): return cls.objects.filter(contester_id=contester_id).exists() and \ (cls.objects.filter(ip_address=ip_addr).exists() or \ cls.objects.filter(voter_id=voter_id).exists()) -
Django Search Vector throws Mysql error when Postgresql is configured
I'm getting an error when using a Search Vector with Django. The weird things is that the error tells me the query on the MySQL database is incorrect, when I'm using PostgreSQL.

Decimal numbers in views.py
I am new to Python/Django, so please bear with me! I have simple django views to sum book values: def portfoyozet(request): librarysum = textshare.objects.filter(user_id=request.user.id).aggregate(Sum('bookvalue'))['bookvalue__sum'] or 0 return render(request, 'todo/libsum.html', {'librarysum': librarysum,}) Which is working perfectly but result isn't show decimal values. 4800,30 becomes 4800,00 I dont need to round or something like that here. I just need to show all values with decimal values.It strikes as a fairly common thing to do but I can't figure out which filter I'm supposed to use. Also found something while googling and change my views.py like: def portfoyozet(request): librarysum = textshare.objects.filter(user_id=request.user.id).aggregate(Sum('bookvalue'))['bookvalue__sum',0.00] or 0 return render(request, 'todo/libsum.html', {'librarysum': librarysum,}) But it doesnt work either. I have to seek help here as a last resort. I really appreciate if someone could help me out. Thank you in advance. -

How to access the items inside a list of query sets in django?

Getting to next page via correct user input in Django
i wanted to create some "riddle" page but i got stuck in creating the functionality of the riddle itself. So what I want to do is, I want to have just a plain html page where i can put some text/pictures etc. and at the end of that block there should be a user input prompt with a commit/send button. If the input is the correct answer to the riddle, the user should get to the next riddle stage. If not, he/she should get an info that the answer wasnt correct. As I am learning Django right now I wondered how it should be designed according to it, and therefore I have no sample code or anything. I would really appreciate some help on how to do that, because from what I understand i would need a function that takes the user input, compares it to some kind of a "solution database" and, depending on input, shows the user the specific page. I already found some more sophisticated site protections to mimic this : https://github.com/MaxLaumeister/pagecrypt/tree/master/python but for my causes i think its a bit over the top. Perhaps this topic is interesting for some of you, Thank you! -
