(Django) Showing simple stats about model instances
What would be the correct approach to create a "stats block" which could be used easily? I've now created a simple page template and view function which returns a list of stats e.g. users and user count by calling User.objects.all().count() How should this be implemented to be able to include these stats in any template? And perhaps with different styles such as list, inline, bootstrap panel etc? -
How to fix issues with Django registration template importation/referencing
I have recently started a blog using django from Corey Schaeffer's tutorial. I am stuck at part 6: User Registration, the feedback says template does not exist at users/register.html at line 19. I have attempted to send the directory in settings to the absolute location of my templates, but it keeps responding with the same feedback. I must be incorrectly referencing in my register.html or settings. Or even worse, a clerical/technical error!

Design Question: Low load data aggregation for overview page
What is the best way to achieve low load on the database or application server for this use case: Let's say I want to build a web application that has for each user an overview page. The overview page shows in an aggregated form for each user the user's data. For example, if it were a library application it would show how many times the user visited the library in total, how many books he read in total, how many books were delivered delayed in total, how many minutes he spend in the building. Each time the user visits the overview page the up-to-date values should be displayed. While the user interacts with the site the numbers change. What I could do is for every overview page refresh do several counts in the database. But that would be expensive. I have thought I could store a JSON object with the data to be presented on the overview page in a database table and I update the JSON each time an event happend on the site which affects the count of objects. Or I could use a materiliazed view but to refresh it I would have to recalculate all the data … -

How to update a M2M field in the related model upon form submission in django
I have a form that schedules a trip, in that form the user can select many vans. Once the user selects their vans, schedules the trip and submits the form, the van should then be marked unavailable in the database. How do I do this properly? I am aware that you can't use .update() on M2M fields. To get around this I tried to get the current form instance, and then from there run .update() on each individual van item that the user selects, but I had trouble getting it set up correctly. I am still new to Django so I am still learning how to deal with these minor tasks. I didn't want to try the .all() query set for fear of changing the availability status of all the vans in the related table. Here is part of the trip builder view: def post(self, request): """Take in user data, clean it, and then post it to the database.""" form = self.form_class(request.POST) # pass in the user's data to that was submitted in form if form.is_valid(): trip = form.save(commit=False) # create an object so we can clean the data before saving it # now get the clean and normalize the … -
How to get celery results model (using django-celery-results) within task
I'm planning on using django-celery-results backend to track status and results of Celery tasks. Is the django-celery-results backend suitable to store status of task while it is running, or only after it has finished? It's not clear when the TaskResult model is first created (upon task creation, task execution, or completion?) If it's created upon task creation, will the model status automatically be updated to RUNNING when the task is picked up, if task_track_started option is set? Can the TaskResult instance be accessed within the task function? Another question here appears to indicate so but doesnt mention task status update to RUNNING Thanks for any help -

How to upload photos by ajax in django?

How to make a Search section in html and search view in django with multiple queries
I am trying to do car sale webpage (educational purpose) and i found out how to make a search but i want to make it look better as it is in many car sale pages with section where it is possible to choose car categories, fuel type, damaged or not etc. my search view for now is this: def search(request): if 'search_filter' in request.GET: search_filter = request.GET['search_filter'] cars = [{ 'id': x.id, 'driven': x.driven, 'description': x.description, 'price': x.price, 'firstImage': x.carimage_set.first().image } for x in Car.objects.filter(description__icontains=search_filter) ] return JsonResponse({'data': cars}) context = {'cars': Car.objects.all().order_by('price')} return render(request, 'cars/car_index.html', context) Now, this perform search if it finds in the description, what I am looking. My goal is to make it so the user can enter the values that wants to search in the input box, like car type, car make, year etc. <!DOCTYPE html> <html> <body> <form action=""> <select name="cars"> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="fiat">Fiat</option> <option value="audi">Audi</option> </select> <legend>Additional Info:</legend> Car Type:<br> <input type="text" name="car_type"> <br> Car Make:<br> <input type="text" name="car_make"> <br><br> <input type="submit" value="Search"> </form> </body> </html> This is a very primitive form, but this is my idea of how i am trying to make it look like.
