Is it possible to combine a django app and a javascript app into one app?
I'm looking for ideas on how to implement the following requirement. I have 2 different applications one being a python Django app and the other one being a pure javascript app. I can get both the apps running on different ports but I need to be able to integrate the js app into the Django app. I.e. I want to add the js app into the Django app such that when you navigate to djangoapp.com/admin/js_app you go to the landing page of the js_app application. the 2 apps are https://github.com/CodeForAfrica/gmmp and https://github.com/OpenUpSA/wazimap-ng-ui any ideas will be appreciated -
Django template : sorting by value of __str__
I am using django 3 and I have surcharged the str function for my model : class SubSubCategory(models.Model): subCategory = models.ForeignKey(SubCategory, on_delete=models.CASCADE) name = models.CharField("Nom du sous sous category" , max_length=200, ) description = models.CharField("Description du sous sous category" , max_length=200, null=True, blank=True) def __str__(self): description_locale = self.name + " : " + self.description if self.description else self.name hierarchie = [str(x) for x in [self.subCategory.category, self.subCategory, description_locale]] description_totale = " > ".join(hierarchie) return description_totale How could I ask my template to order my list according to this str representation ? I would like to do something like : {% for SubSubcategory in object_list|dictsort:'str' %} but it obviously doesn't work, as "str" is nothing. How do I call the string representation of an object in a template ? to pass it as an ordering order ? -

Django, Archery System
This is more a plea for guidance rather than any hard coding example. I have set myself a problem to write an archery recording system using Django. I have got the recording system working well and the system can register users, record their scores, show their scores filtered by round, show the users scores who have shot a particular round etc. This issue I have got is when it comes to classifying the score. I will explain: In archery scores are recorded against the round you shoot. These vary so you have 60+ rounds to choose from each having different criteria and different maximum scores. Archers are grouped according to gender and age (10 sub groups) The classification system works by taking the round shot and the sub-group that the archer falls into and looking across a table of values. The classification gained is the one that the score falls into i.e. if you are male and over 18 you are grouped as a 'Gentleman' The round you shoot is called a 'York' and you score 550 The table you would consult would look like this Round | 3rd Class | 2nd Class | 1st Class | Bowman | Master … -

Stripe CLI webhook not invoked when card declined
I am using the stripe CLI to test webhooks in my django application. When a payment goes through, the webhook records this and seems to work perfectly fine. However, whenever I am using one of the stripe test cards that get declined (such as: 4000000000009987), its as if the webhook never gets called, even though stripe tells me the error that the card was declined. It's as if the webhook never even gets called from stripe when a payment fails.
