Javascript code not working using template inheritence in Django template
I am having trouble in executing Javascript code in a Django project. The following is working fine - i.e. without using template inheritence html: <!DOCTYPE html> <html> <head> {% load static %} <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous"> <script src="https://code.jquery.com/jquery-3.4.1.slim.min.js" integrity="sha384-J6qa4849blE2+poT4WnyKhv5vZF5SrPo0iEjwBvKU7imGFAV0wwj1yYfoRSJoZ+n" crossorigin="anonymous"></script> <script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.0/dist/umd/popper.min.js" integrity="sha384-Q6E9RHvbIyZFJoft+2mJbHaEWldlvI9IOYy5n3zV9zzTtmI3UksdQRVvoxMfooAo" crossorigin="anonymous"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.min.js" integrity="sha384-wfSDF2E50Y2D1uUdj0O3uMBJnjuUD4Ih7YwaYd1iqfktj0Uod8GCExl3Og8ifwB6" crossorigin="anonymous"></script> <script src="{% static 'ads/test.js' %}" type="text/javascript"></script> <title> Test </title> </head> <body> <form action="{% url 'test' %}" method="post" id="my_form"> {% csrf_token %} <button type="submit" class="btn btn-success">Submit</button> </form> </body> </html> test.js $(document).ready(function() { $("#my_form").submit(function(){ alert('submitted'); }); }); Since the above external Javascript file test.js has executed successfully, I assume the settings of static url, static dirs, etc. are correct. Also, since jquery has worked, I assume the order of jquery first, then js code is also correct.

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. -

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. I am able to implement it with a javascript window.open() function. But after login, the app continues (successfully) on the created window. How do I get it to close itself and redirect the parent to the appropriate redirect_after_login_page? Is there any native way in Django to implement popup windows? -
