How to filter django models based on ManytoMany relationhsip and on math calc
Guys i am learning Django and models linking to DB quite confusing for me. I would like to gte your help/guidance . Any help is very much welcomed. I have 4 models: class Profile(models.Model): player = models.CharField(max_length=150) surname=models.CharField(max_length=200) class Meta: db_table='profile' class race19(models.Model): player = models.CharField(max_length=150) profile=models.ManyToManyField(Profile) score19=models.DecimalField(decimal_places=2,max_digits=1000) distance=models.DecimalField(decimal_places=2,max_digits=1000) class Meta: db_table='race19' class race18(models.Model): player = models.CharField(max_length=150) profile=models.ManyToManyField(Profile) score18=models.DecimalField(decimal_places=2,max_digits=1000) distance=models.DecimalField(decimal_places=2,max_digits=1000) class Meta: db_table='race18' class adjustments(models.Model): player = models.CharField(max_length=150) profile=models.ManyToManyField(Profile) bonus=models.DecimalField(decimal_places=2,max_digits=1000) class Meta: db_table='adjustments' I explored django docs and could learn filtering just from 1 table as fowllowing : score_m=race19.objects.annotate(score_margin=F('score19') / F('distance')).filter(score_margin__gt=0.4,) Now i want to be able to get values such as score19, score18, bonus from different tables and i though ManytoMany would help and tried the following: score_growth=race19.objects.annotate( score_change=((F('score19')+F('bonus')) / F('score18')).filter(score_change__gt=0.10,) But this does not work. What i needed to do. Would appreciate if you could share code as thereby i would better understand. Thanks in advance. -

invalid syntax in views.py in Django
The code was working. However, I got the error suddenly that can be seen in the image invalid_syntax_error . Even though the name of view and the name of function are same(in this case "addArticle"), I got this error. How can I fix that issue? Here is what my urls.py contains; from django.contrib import admin from django.urls import path from . import views app_name = "article" urlpatterns = [ path('dashboard/',views.dashboard,name = "dashboard"), path('addarticle/',views.addArticle,name = "addarticle"),] -
Django CreateView: How to create the resource before rendering the form
I have a model class for my resource, class Article(db.Model): title = models.CharField(_('title'), max_length=255, blank=False) slug = AutoSlugField(_('slug'), populate_from='title') description = models.TextField(_('description'), blank=True, null=True) content = RichTextUploadingField() Here's my form class class ArticleForm(ModelForm): class Meta: model = kb_models.Article And finally my CreateView, class CreateArticleView(generic.CreateView): form_class = ArticleForm model = Article def get_success_url(self): return "some_redirect_url" Right now I have configured my URLs like below, path('add/', CreateArticleView.as_view(), name='create_article') path('<slug:article>', ArticleDetailView.as_view(), name='article_detail'), path('<slug:article>/update', UpdateArticleView.as_view(), name='update_article') The current flow will render a form when I hit the add/ resource endpoint, and save the resource in the database only after I submit the form. After that, the article can be accessed using the slug generated from the title. What I want instead is to be able to create the Article resource before the resource is rendered, so that the add/ endpoint redirects to some add/unique-uuid endpoint, and even when the form is not submitted from the browser, this empty resource is preserved, and it can be accessed later on because of the unique-uuid. I thought of instantiating an object and redirecting that to UpdateView, but I am having difficulties in figuring out how to keep track of the unique-uuid and point both generated-uuid and slug … -
Django - LANGUAGE_CODE - 'en-IN' does not work, but 'hi-IN' works
Django version 2.2 and 3.0 Purpose: I would like to display numbers in India locale format. For e.g. 1000000 should be displayed as 10,00,000 Action To do this, I went to settings.py and made the following changes: LANGUAGE_CODE = 'IN' - date and time was displayed in Indonesian format but grouping of numbers were correct LANGUAGE_CODE = 'en-IN' - date and time was displayed properly but grouping of numbers were incorrect LANGUAGE_CODE = 'hi-IN' - date and time had Hindi language display but grouping of numbers were correct What I want LANGUAGE_CODE = 'en-IN' to display date and time properly and also do number grouping My settings.py file : LANGUAGE_CODE = 'en-IN' TIME_ZONE = 'Asia/Kolkata' USE_I18N = True USE_L10N = True USE_THOUSAND_SEPARATOR = True NUMBER_GROUPING = (3,2, 0) USE_TZ = True I had a look at Number Grouping which actually talked about this but I believe documentation is misleading. For starters they have put language code as en_IN which doesn't work. Let me know if any additional information needed. -

Copying dataframe column dict into Django JsonField
I have a table created with Django(3+) on a postgres database (10+). Class Cast(models.Models): profiles=JSONField(null=True) I am trying to copy a dataframe with a column full of python dict of the form {'test':'test'}. When I use the command: df.to_sql('cast',engine,if_exists='append') I get the following error: (psycopg2.ProgrammingError) can't adapt type 'dict' I tried replacing my dict by None and it worked well. I have correctly added 'django.contrib.postgres' in INSTALLED_APPS ( I don't know if this should be done before creating the database but I guess not) I must add that the postgres database is on a remote server, the django code is on my local computer and the code to copy the dataframe on a second remote server. -

How to create a google sign-in popup window that gets closed after login success in Django
I am creating a Django app that allows google sign-in (using python-social-auth). I want the google sign-in page to open in a new window.

cleaned_data is returning wrong/different value

And so on. class PopulationForm(forms.Form): districts = forms.ModelChoiceField(queryset=Population.objects.order_by('districtid').values_list('districtid',flat=True).distinct()) There are 4 options for a user to choose from: 2,3,4,5.

Django 3.0.3 IntegrityError FOREIGN KEY constraint failed when making changes to db
I have two models in my database, an 'Account' model (which is a custom user model) and a 'Return' model. My database worked fine up to the point of adding the 'Return' model, which has a ForeignKey relationship with the 'User' model, which I suspect is causing the problem. (Each return belongs to an existing user. In the admin panel, the option box is populated with existing users so I thought this was working correctly?) Appreciate any help with this!

Somehow I found that {% load custom %} is not working because add function defined is not working. How to solve this error please help !!
