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
I have been struggling with the Forms in Django. Able to get the value from the cleaned_data but it returns a totally different number. For example, I have 4 values to choose from (2,3,4,5). If I select 2, it will give cleaned_data.get(name_of_form_field) returns 5. 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. If the user selects 2, it returns 5 and so on. I am not sure what's happening. Here is my views.py: if request.method == 'POST': form = PopulationForm(request.POST) if form.is_valid(): print(form.cleaned_data.get('districts')) return HttpResponse(form.cleaned_data.get('districts')) Here is my template: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Django Forms Tutorial</title> </head> <body> <h2>Django Forms Tutorial</h2> <form action="/display/" method="post"> {% csrf_token %} <table> {{form.as_table}} </table> <input type="submit" value="Submit" /> </form> </body> </html> -

Django 3.0.3 IntegrityError FOREIGN KEY constraint failed when making changes to db
