Disable CSRF validation on Wagtail Page
I'm trying to do a curl POST request on a wagtail page. Unfortunately I hit the CSRF protection. I tried to disabled CSRF on this specific type of page using the @csrf_exempt decorator, without success. Here is my pseudo code (one of many attemps): @method_decorator(csrf_exempt, name='serve') class NewsletterPage(MedorPage): class Meta: verbose_name = _("newsletter page") Seems like the csrf verifition is done even before the serve method is called. Any idea? thanks -

Django search : query multiple table, join them then return the queryset
I'm building a search for my product price tracking app and there're 2 models products and scans class products(models.Model): product_id = models.IntegerField(primary_key=True) product_name = models.CharField(max_length=100) product_link = models.CharField(max_length=255) image_link = models.CharField(max_length=100) store_name = models.CharField(max_length=100) class Meta: verbose_name_plural = "products" def __str__(self): return str(self.product_name) class scans(models.Model): scan_id = models.IntegerField(primary_key=True) prod_id = models.IntegerField(models.ForeignKey("scrape.Model", on_delete=models.CASCADE)) price = models.IntegerField() scanned_time = models.DateTimeField(default=timezone.now) class Meta: verbose_name_plural = "scans" def __repr__(self): return str(self.prod_id) the search is supposed to take a name(string) input and query for a store name in the same table and query for price which is in another table and return the query set with the product_name, store_name and price. I've tried this class searchResults(ListView): model = 'products', 'scans' template_name = 'result.html' # let query = GET request from form (in home.html) def get_queryset(self): queryset = [] rawquery = self.request.GET.get('q') queries = rawquery.split(" ") for q in queries: prodresults = products.objects.filter( Q(product_name__icontains=q) ).distinct() for prodresult in prodresults: prod_id = products.objects.get(product_name=prodresult).product_id prod_price = scans.objects.get(prod_id=prod_id).price for result in prodresults: #joins results toegther queryset.append(result) queryset.append(prod_price) return list(set(queryset)) The code broke at prod_price = scans.objects.get(prod_id=prod_id).price with scans matching query does not exist. -

How to support django data migration in a plugin design

Redirect to item page after deleteView in class based views
I have an invoice page with each invoice (factuur) has items in it (relation invoice-items with ForeignKey). When I delete one of the items with the class based deleteView I want to redirect back to the specific invoice id with the remaining items in it. urls.py: path('factuur/<factuur_id>', views.facturen_detail_view, name='facturen_detail_view'), path('delete/<int:pk>', views.FactuurItemDeleteView.as_view(), name='delete_factuurItem'), views.py: class FactuurItemDeleteView(BSModalDeleteView): model = FactuurItems template_name = 'delete_fitem.html' success_message = 'Succes: factuur item is verwijderd.' success_url = reverse_lazy('facturen_detail_view') So what I want is redirect it to /factuur/factuur_id after deletion (where I was at the moment of clicking the delete button). But how do I redirect as I need to know invoice id (factuur_id) in the first place. I don't know how to do this with the class based views method. When success_url is as above then it tries to redirect to the factuur_id with the deleted item_id what is not the wanted situation. -

how to fetch data in chunks from db in django and then delete them?
My basic problem statement is that I want to fetch every row but in chunks only 2000 rows at one time from a table having 1 million rows. And after these chunked queries are evaluated i want to delete every row. so just say i have a = Model.objects.filter(id=1<2000) b = Model.objects.filter(id=2000<4000) c = Model.objects.filter(id=4000<6000) .. .. now if i combine all these queryset into one queryset by some means say del = a + b + c +d ...... and i do del.delete() so will it delete all the rows in less time or it will re process queries again to delete them and will take time? -
Django url dispatcher calls the wrong function
the problem that I have is this one: I created a new re_path in my urls.py file, but when I make a request at that url the wrong function is called. # myapp/urls.py from django.urls import path, re_path from . import views as multiplayer_lite_views urlpatterns = [ # other paths re_path(r'vote/(?P<match_id>\w{16})', multiplayer_lite_views.vote, name='multiplayer_lite_vote'), re_path(r'nightvote/(?P<match_id>\w{16})', multiplayer_lite_views.night_vote, name='multiplayer_lite_night_vote'), path('new-match/', multiplayer_lite_views.new_match, name='multiplayer_lite_new_match'), path('', multiplayer_lite_views.home, name='multiplayer_lite_home'), ] what I did was simply duplicate the line re_path(r'vote/... and renamed it to re_path(r'nightvote/... but changing also all the other info, like multiplayer_lite_views.vote to multiplayer_lite_views.night_vote. The problem is that when I go to this url nightvote/ the function vote is called. # myapp/views.py def vote(request, match_id): print('vote function') # do other stuff return return JsonResponse(...) def night_vote(request, match_id): print('nightvote function') # do other stuff return return JsonResponse(...) In the server side what I see is that: ... vote function [18/Mar/2020 10:19:16] "POST /nightvote/gfvkpvhlwlqzosae HTTP/1.1" 200 16 ...
