Reverse django admin custom url with two parameters
I have the following custom admin url def get_urls(self): (...) info = self.model._meta.app_label, self.model._meta.model_name urlpatterns = [ path('<path:object_id>/CompareParameters/<int:parameter_id>', wrap(CompareParameters.as_view()), name='%s_%s_CompareParameters' % info), ] and I need to call it from an inline and it takes two parameters (the fact the view's name includes word parameters is just a coincidence) I have tried to do it like so def pair_parameter(self, obj): return mark_safe(f'<a style="padding: 5px; background-color: lightblue;" target="_blank" href="{reverse("admin:agregator_agregatorproduct_compareparameters", args=[obj.ProductId_id, obj.DistributionParameterId_id, ])}">Spárovavat parametr</a>') or like so def pair_parameter(self, obj): return mark_safe(f'<a style="padding: 5px; background-color: lightblue;" target="_blank" href="{reverse("admin:agregator_agregatorproduct_" + str(obj.ProductId_id) + "_" + str(obj.DistributionParameterId_id) + "_compareparameters")}">Spárovavat parametr</a>') and by a few other combinations with no success. What would be the right way to do it? The final URL looks eg like this .../admin/agregator/agregatorproduct/1854146/CompareParameters/9330 where the first arg is obj.ProductId_id and 2nd is obj.DistributionParameterId_id Thank you in advance. -

Django @ mention user using Django Custom Tags

I would like to get back the post just as it is but with the user @faces as a hyperlink to the users profile. This is my custom tag from the custom templates that I am using.

How to download large file from Cloud Run in Django
I have Django project on Cloud Run. When I download small file from page which has below code. def download_view(request,pk): file_path = f'media/{pk}.mp3' name = f'{pk}.mp3' with open(file_path, 'rb') as f: response = HttpResponse(f.read(), content_type='audio/wav') response['Content-Disposition'] = f'attachment; filename={name}' return response It's works fine. However, when I download a file (50MB). I got this pictures error. Cloud run's log is like this. I couldn't find any log of traceback. 2021-05-06 12:00:35.668 JSTGET500606 B66 msChrome 72 https://***/download/mp3/2500762/ 2021-05-06 11:49:49.037 JSTGET500606 B61 msChrome 72 https://***/download/mp3/2500645/ I'm not sure. Is this error related with download error. 2021-05-06 16:48:32.570 JSTResponse size was too large. Please consider reducing response size. I think this is upload file size error. So this is not related with this subject of download error. When I run Django at local, then download same 50MB file. I can download it. I think this download error related with Cloud run. It's stop after request/response. So I think this error coused by Cloud Run. Which was stoped, when I'm still downloading file. I don't know how to solve this download error. If you have any solution, please help me! -

How do I create a multidimensional table in SQL? Or should I use some other DBMS?
I want to use a DB for creating languages (as a hobby), and I went with SQLite. Of course, to save myself some trouble, I decided to write myself a user-friendly interface in the form of a web-app using Django. I already got sa few pages up. Then I stumbled upon this issue that I need to be able to somehow store in my DB that, e.g., a verb has the categories of Mood, Tense, Gender, Person and Number, with Number only relevant for Indicative Mood; Person only relevant for Indicative Mood, Present and Future Tenses; and Gender only relevant for Indicative Mood, Past Tense, Signular Number. Basically, I need to be able to check the values of each category (like Mood, Tense, Gender, Person, Number, so forth) against the values of every other category, and I need this to be as flexible as possible because grammatical geometry of every language is very differnet and I want to be able to reflect that in my DB. I guess what I'm looking for is a multidimensional table, where every dimension is a separate category, but I'm not sure how to do that using SQLite, with the means of Django no less. … -

Django Redirect: No errors, but no redirect
I POST some data via an HTML form using AJAX to modify data in my database. The data is successfully modified by executing stored procedures on the DB. Final line of the view.py function call is return redirect('Home'). The redirect is successfully executing, but I am not being redirected. I can overcome this by adding window.location.href = 'http://127.0.0.1:8000/ in the success function of the AJAX call. The problem is, I want to use messages.success(request, 'Data Successfully Updated'), which only appears after refreshing the AJAX-originating redirect. Is there a reason why return redirect('Home') is not working here, and is there a way to overcome this?

Conditionally authenticate users to DRF view
I have a DRF view as such: class DocumentsView(generics.ListCreateAPIView): permission_classes = () authentication_classes = () # I typically enforce authentication with # authentication_classes = (JWTCookieAuthentication,) def list(self, request): pagination_class = None if request.user.is_authenticated: ... return protected data ... else: ... return generic data ...

However, request.user.is_authenticated returns False, even when a valid token is sent (I understand why). How can I try to authenticate the user, but still allow them to proceed even if not presenting a token? Or is better practice to not have the same view to authenticated an unauthenticated users? -
