What does the underscore before the label value in Django forms mean
I have came through the UserCreationForm in the django source code here. Here is the question, if you look at both password fields you will see an underscore before the label value, I wonder what's the purpose of it, because it's not written in the documentation since I searched for it. class UserCreationForm(forms.ModelForm): """ A form that creates a user, with no privileges, from the given username and password. """ error_messages = { 'password_mismatch': _('The two password fields didn’t match.'), } password1 = forms.CharField( label=_("Password"), strip=False, widget=forms.PasswordInput(attrs={'autocomplete': 'new-password'}), help_text=password_validation.password_validators_help_text_html(), ) password2 = forms.CharField( label=_("Password confirmation"), widget=forms.PasswordInput(attrs={'autocomplete': 'new-password'}), strip=False, help_text=_("Enter the same password as before, for verification."), ) -
Improve performance of processing API created using Django-rest-framework
I want the above API "story": { "pranay": [ 9, 2 ], "eeee": [ 8, 6, 4, 3, 1 ], "pranay56n": [ 5 ] } And I am getting it using the method below. But there is a problem it is okay to have the method if my objects are less but if there are 100000 objects than it will lower the performance. class Follow(models.Model): user = models.OneToOneField(User, verbose_name=_("User"),related_name="user" ,on_delete=models.CASCADE) following = models.ManyToManyField(User, verbose_name=_("Following"),related_name='is_follower',blank=True) class StorySerializer(ModelSerializer): story = SerializerMethodField() class Meta: model = Stories fields = ('story',) def get_story(self,request): user = self.context.get("request").user follower_ids = [x.pk for x in user.user.following.all()] qs = Stories.objects.filter(user__id__in=follower_ids, active=True).order_by('-date_created').values_list('user__username',flat=True) data = {} for obj_user in qs: data[obj_user]=Stories.objects.filter(user__username__exact=obj_user, active=True).order_by('-date_created').values_list('pk',flat=True) return data Is there any way that will increase its performance? -
Which method is the most efficient and fast for Tag functionality, using content types or using manytomany field for diff apps in a django project?

Bitbucket cloning into Linux server
I have read: BitBucket: Host key verification failed and Jenkins Host key verification failed and several other links provided. I seem to find myself in an odd situation. I want to clone my django repo into a digital ocean droplet. I am following the steps of this document. https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04 .

Django Adding User details to a UserPost List View
I have a UserPost List View which is a view for a specific user's posts. I am looping the posts of this specific user but I want to add this user's profile details like profile image and other details like email. So, I am not sure on how to add the user details of the user's post names as designer not the logged-in user. I can add the user/designer details in every looped post but I don't want it to be repeated with every post I just want it to appear once just like {{ view.kwargs.username }} as this page is realted only to this user/designer Here is the models.py class Post(models.Model): designer = models.ForeignKey(User, on_delete=models.CASCADE, related_name="post") title = models.CharField(max_length=100, unique=True) here is the profile model related to every user class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default='default.jpg', upload_to='profile_pics') class UserRegisterForm(UserCreationForm): email = forms.EmailField() first_name = forms.CharField() last_name = forms.CharField() class Meta: model = User fields = ['username', 'first_name', 'last_name', 'email'] here is the views for the userpostlist which is filtered by a specific user/designer not the logged in user class UserPostListView(ListView): model = Post template_name = "user_posts.html" context_object_name = 'posts' queryset = Post.objects.filter(admin_approved=True) paginate_by = 6 def get_queryset(self): … -
Why does Django template block/include include external <table> tag?
Consider the below code: <table id='table1'> {% if model_name == 'TransactionsTable' %} {% block transactions_create %} {% include "snippets/transactions_create_and_update.html" with form=form %} {% endblock transactions_create %} {% endif %} </table> I have another <table>, 'table2', within transactions_create_and_update.html. Table2 was appearing outside of it's parent element. So after some testing I tried closing table1 early (first line): <table id='table1'></table> {% if model_name == 'TransactionsTable' %} {% block transactions_create %} {% include "snippets/transactions_create_and_update.html" with form=form %} {% endblock transactions_create %} {% endif %} Then table2 behaves as expected. So table1 is kind of included in the include/block inheritance - but the template doesn't seem to know that I close it after. From the docs - think this is part of the answer but I don't know what to do with it: The include tag should be considered as an implementation of “render this subtemplate and include the HTML”, not as “parse this subtemplate and include its contents as if it were part of the parent”. This means that there is no shared state between included templates – each include is a completely independent rendering process. Blocks are evaluated before they are included. This means that a template that includes blocks from another … -

Django compute score of matches (workaround to annotate a query after a union)
I need to compute the ranking of athletes during boxing tournaments. In my models, I track the result of each match and the points to be attributed for each outcome to each athlete. class Member(models.Model): surname = models.CharField(max_length=200) last_name = models.CharField(max_length=200) class Tournament(models.Model): name = models.CharField(max_length=200) class TrophyRule(models.Model): win = models.IntegerField() loose = models.IntegerField() draw = models.IntegerField() class Ring(models.Model): code = models.CharFieldmax_length=1) tournament = models.ForeignKey(Tournament, on_delete=models.CASCADE) class Match(models.Model): ring = models.ForeignKey(Ring, null=True, on_delete=models.SET_NULL) winner = models.CharField(max_length=20, null=True, blank=True) trophy_rule = models.ForeignKey(TrophyRule, on_delete=models.SET_NULL, null=True) red_member = models.ForeignKey(Member, related_name='reds', on_delete=models.SET_NULL, null=True) red_count_ranking = models.BooleanField(default=True) blue_member = models.ForeignKey(Member, related_name='blues', on_delete=models.SET_NULL, null=True) blue_count_ranking = models.BooleanField(default=True) Based on this model, I need to sum the points acquired when the athlete was in the red corner with the points acquired when the athlete was in the blue corner. The result should be a queryset with all members and their total number of points. In order to achieve this, I started with the computation of the points acquired by the athletes in the red corner: from apps.members.models import Member from django.db.models import Case, Sum, When, Q red = Member.objects.filter(reds__ring__tournament_id=11402).annotate( points=Case( When(Q(reds__winner='red') & Q(reds__red_count_ranking=True), then='reds__trophy_rule__win'), When(Q(reds__winner='draw') & Q(reds__red_count_ranking=True), then='reds__trophy_rule__draw'), When(Q(reds__winner='blue') & Q(reds__red_count_ranking=True), then='reds__trophy_rule__loose'), ), ) I also did … -
Django - Retrieve a field for split operation from sorted chain list
