How to get error messages from a celery task in Django
I have an API endpoint to allow clients to upload data into the database. In the back-end, a UploadView will check the uploaded file format, and pass the data file to a celery task, by delaying the task and calling it asynchronously. As long as the file is in expected format, the client will get HTTP_202_ACCEPTED response. A potential problem is, what if the data is not accepted during the delayed task? e.g. primary key already existed in database. What's the best way to let API clients be aware of such errors from a celery task? -

Zappa Django app deployed but custom domain not working

Django. How to correctly save time & timezones
I have this code that behaves in a rather strange way and opens the question, how should I deal with timezones? So, first I have a datetime object I build from the info a user posts: time_zone = request.POST.get("time_zone") date_start = request.POST.get("date_start") time_day = request.POST.get("time_day") time_zone_obj = pytz.timezone("Etc/" + time_zone) # GMT + 2 in this example date_start = datetime.strptime(date_start, "%d/%m/%Y") date_start = date_start.replace(tzinfo=time_zone_obj) time_day = datetime.strptime(time_day, "%I:%M %p") date_start = date_start.replace(hour=time_day.hour, minute=time_day.minute) ... event.date_start = date_start event.save() print("event.date_start.hour:%s" % event.date_start.hour) return redirect("event_detail", event_id=event.id) This prints event.date_start.hour:6. Then, inmediatlty after saving the object and printing the hour, it redirects to the event_detail view, very simple: def event_detail(request, event_id): event = get_object_or_404(Event, id=event_id) print("event.date_start.hour:%s" % event.date_start.hour) ... And it prints event.date_start.hour:8. I don't understand why. Plz note that I printed the hour after I saved the object and then after I retrieved it in the other view. It has a difference of two hours that must have something to do with the timezone the user selected (GMT + 2). Why is this? Which is the best way to save this data? The user submits "6:00 AM" + "GMT+2" in the form and then later when I want to show the time … -

Importing and creating pages in Django / Wagtail
Although Wagtail and Django seem to be very efficient and sophisticated frameworks, they do not offer any simple way of importing (i.e bulk creating) pages. I have tried dozens of suggestions to do so (eg 1, eg 2, eg 3, eg 4, etc). I've also tried CodeRedCMS (which is based on Wagtail), but it offers a very rudimentary function which have so far not helped me. Gazmans solution in this post seemed very efficient but I could not figure out exactly how to go about solving the issue. So my question is simple: If I have a csv/json file with thousands of rows, where each row represents a post for a specific Page Model I've created in Wagtail, how do I import it to Wagtail? Any example with psuedo code would be immensely appreciated. The only solution that I did (almost) succeed with was by using DataGrip and directly import data into the table, but then Wagtail did not register the entries for some reason. -
Django foreign key not getting data
I have two tables defined in my models: class Products(models.Model): productsid = models.AutoField(primary_key=True) product_number = models.CharField(db_index=True, max_length=15) title = models.CharField(max_length=255, default=None, null=True, blank=True) date = models.DateField(db_index=True, default=datetime.date.today, null=True, blank=True) class ProductFlag(models.Model): product_number = models.CharField(db_index=True, max_length=15) company = models.ForeignKey(Company, db_index=True, on_delete=models.SET_NULL, null=True) productid = models.ForeignKey(Products, db_column='productsid', db_index=True, on_delete=models.SET_NULL, null=True) I want to get the the 'title' from Products when I query ProductFlag. In my views, I make this query: productflags = ProductFlag.objects.filter(company__companyid=self.kwargs.get('company_id')).order_by('product_number') I thought that I could then reference the title field in my template by looping through {% for product in productflags %} and grabbing {{ product_number.productid.title }}, but I get nothing at all. Looking at it in the Django shell, it seems that my productid is always "None" (and my database definitely had data in productsid). I have no issue with the company foreign key. What am I doing wrong? Thanks-- Al -
