Django CSV Export - Foreingkey
Export to CSV is working properly... BUT the only thing is that the model fields which are defined via a ForeignKey are outputted as their PK... How can I solve this? Below the code in my views.py : def export_cashflow_csv(request): response = HttpResponse(content_type='text/csv') response['Content-Disposition'] = 'attachment; filename="cashflow.csv"' writer = csv.writer(response) writer.writerow(['date', 'type', 'amount', 'fund', 'description']) cashflows = CashFlow.objects.all().values_list('date', 'type', 'amount', 'fund', 'description') for cashflow in cashflows: writer.writerow(cashflow) return response the field fund is a Foreignkey to the model Fund. many thanks all ! -
Django. Add, edit and delete on django
Tell me, please, what will the function for adding, editing and deleting listings look like? First, how to correctly register the current user in this function? Secondly, how to ensure that only the current user can delete and edit listings? At the moment, this can be done by anyone, even an unregistered user. def listing_delete(request, listing_id): listing = Listing.objects.get(id=listing_id) listing.delete() return redirect('index') def listing_edit(request, listing_id): form = ListingForm(instance = Listing.objects.get(id = listing_id)) if request.method == "POST": form = ListingForm(request.POST, request.FILES, instance = Listing.objects.get(id = listing_id)) if form.is_valid(): listing = form.save() return redirect('listing', listing_id) else: ListingForm(instance=Listing.objects.get(id = listing_id)) return render(request, 'listings/listing_edit.html', {'form': form}) def listing_add(request): form = ListingForm() if request.method == "POST": form = ListingForm(request.POST, request.FILES) if form.is_valid(): listing = form.save(commit=False) listing.realtor = request.user listing.save() return redirect('dashboard') return render(request, 'listings/listing_add.html', {'form': form}) I understand that listing.realtor = request.user is wrong, because there must be an instance of a realtor, but I didn’t understand how to do it correctly.

PyQt5 : How to Upload Image using HTTP Request ( Multipart-form )
currently I am working in a project to create a seller application where the seller can upload the menu picture and some additional information such as the price and the name of the menu. but I stuck at the POST request method because in this time I have to upload an image with some text data instead of only text data. I am using PyQt5. This is my API web server. I am using Django Rest Framework to build that. [ I have tried to use this answer: here This is my implementation to that method: def upload(self): file1 = QFile("/home/shalahuddin/Desktop/jamu.jpg") file1.open(QFile.ReadOnly) url = "http://127.0.0.1:8000/api/menu/" nama = QByteArray() nama.append("ABCD") harga = QByteArray() harga.append(str(999)) kategori = QByteArray() kategori.append(str(0)) ada = QByteArray() ada.append(str(True)) idseller = QByteArray() idseller.append(str(2)) data = {"name": nama, "price": harga, "category": kategori, "availability": ada, "sellerID": idseller} files = {"image": file1} multipart = self.construct_multipart(data, files) request_qt = QNetworkRequest(QUrl(url)) request_qt.setHeader(QtNetwork.QNetworkRequest.ContentTypeHeader, 'multipart/form-data; boundary=%s' % multipart.boundary()) self.manager = QtNetwork.QNetworkAccessManager() self.manager.finished.connect(self.handleResponseMenu) self.manager.post(request_qt, multipart) def handleResponseMenu(self, reply): er = reply.error() data = json.loads(str(reply.readAll(), 'utf-8')) file = open("/home/shalahuddin/Desktop/testfile.txt", "w") file.write(str(reply)) if er == QtNetwork.QNetworkReply.NoError: bytes_string = reply.readAll() data = json.loads(str(bytes_string, 'utf-8')) # print(data) QMessageBox.information(self, "Menu", "Upload Success!") else: errorMessage = "Error occured: " + str(er) + … -
Celery + Redis - Django blocks when triggering a task with delay
I have setup Celery on my Django project with Redis. The scheduled tasks are running without issues. The problems come when triggering an async task using the delay(). The execution stops and it's like is blocked in the loop of kombu.utils.retry_over_time. I checked and Redis is up and running. I don't really know how to debug this issue.

How to annotate a Django QuerySet aggregating annotated Subquery
I have a few Django models with a FK relationship between them: from django.db import models class Order(models.Model): notes = models.TextField(blank=True, null=True) class OrderLine(models.Model): order = models.ForeignKey(Order, on_delete=models.CASCADE) quantity = models.PositiveIntegerField() price = models.DecimalField(max_digits=8, blank=True, decimal_places=2) Given an OrderLine you can calculate its total as quantity by price: def get_order_line_total(order_line): return order_line.quantity * order_line.price Given an Order you can calculate its total as the sum of its order lines totals: def get_order_total(order): order_total = 0 for orderline_for in order.orderline_set.all(): order_total += (order_line_for.quantity * order_line_for.price) return order_total I want to annotate that totals in querysets so I can filtrate them, sort them, etc. For the OrderLine models I found it pretty straight forward: from django.db.models import F, FloatField, Sum annotated_orderline_set = OrderLine.objects.annotate(orderline_total=Sum(F('quantity') * F('price'), output_field=FloatField())) Now I want to annotate the total in an Order.objects queryset. I guess I would need to use a Subquery but I can't make it work. My guess is (Not working): from django.db.models import F, FloatField, OuterRef, Subquery, Sum Order.objects.annotate( order_total=Subquery( OrderLine.objects.filter( order=OuterRef('pk') ).annotate( orderline_total=Sum(F('quantity') * F('price'), output_field=FloatField()) ).values( 'orderline_total' ).aggregate( Sum('orderline_total') )['orderline_total__sum'] ) ) # Not working, returns: # ValueError: This queryset contains a reference to an outer query and may only be used in … -
Is it safe to use GZip Middleware in Django >= 1.10?
I am looking to enable text compression in Django. The performance docs reference GZip Middleware as the current solution for text compression. However, it comes with a stern warning: GZipMiddleware Compresses responses for all modern browsers, saving bandwidth and transfer time. Note that GZipMiddleware is currently considered a security risk, and is vulnerable to attacks that nullify the protection provided by TLS/SSL. See the warning in GZipMiddleware for more information. A couple of questions: Are there any text compression alternatives I can use with Django that are not subject to security risks? If I use CSRF tokens when using POST and I have CSRF Middleware enabled am I safe? Again, via the docs: Changed in Django 1.10: In older versions, Django’s CSRF protection mechanism was vulnerable to BREACH attacks when compression was used. This is no longer the case, but you should still take care not to compromise your own secrets this way. -
How to get request parameters from an encoded URL in Django?
I am using Django Rest Framework. The API receives GET requests with json objects encoded into the URL. For example: /endpoint?%7B%0D%0A++%22foo%22%3A%5B%22bar%22%2C%22baz%22%5D%0D%0A%7D Where the decoded parameters are { "foo":["bar","baz"] } I can't find anything in the documentation for Django or DRF pointing to how the framework can handle this so that I get a QueryDict with the json objects in it by doing something like: request.query_params # Should yield a dict -> {foo=[bar,baz]} How can I decode JSON encoded URLs in Django Rest Framework? Note that my actual parameters are much more complex. Using POST is not an because the caller relies heavily on caching and bookmarking -
Not able to create object in Django
I am new to Django and I am struggling to create and save an object based on a model in my apps models.py The code I am using: search = Searches(product=product, no_of_sellers=len(listed), valid_search=1, best_price=listed[0]['cost'], worst_price=listed[-1]['cost']) search.save() And my models.py looks like this: class Searches(models.Model): id = models.AutoField(primary_key=True) product = models.CharField(max_length=8) no_of_sellers = models.IntegerField() valid_search = models.BooleanField() best_price = models.FloatField(blank=True) worst_price = models.FloatField(blank=True) timestamp = models.DateTimeField(auto_now_add=True) Additionally, print statements that I have after search.save() are not executed, so it appears the object creation is failing and then not executing the rest of the function. I am no getting any error messages in the console and nothing is happening in my Database. As far as I can see, I'm doing exactly as stated in the Django Docs example: p = Person(name="Fred Flintstone", shirt_size="L") p.save() I'm using a MySQL database, Python 3.6, and Django 2.1.7. Any help on this would be greatly appreciated! -

angular redirect to backend app on same host
I've got an app with Angular in the front end and Django in the backend on different ports on the same host, and for authentication, I have this piece of code in my userService.js: authenticateUser: function() { return $window.location.href = 'https://myhost:backend_port/oidc/auth/request/' }, but when I visit my app, it's giving me "cannot GET /oidc/auth/request/" so I think the front end is trying to handle it when it should be going to the backend.

Django cache framwework - get_or_set()

Giving admin users flexibility on defining calculation formula for web app... is it a good idea?
I'm designing a Django project, for which I'd like to give administrators flexibility on defining certain calculation formulas. Although I can assume that admins won't do stupid things break the system by defining unappropriate formulas, I'm feeling very uncomfortable on the ways this freedom can be implemented: Saving the code of the formula to the database, fetch it when the formula is needed and apply it. Allowing admin users to write Python modules, save them to a preset location, save the module and function name in the database, fetch it when the formula is needed and apply it. Both ways look like huge security holes to the system, and I'd like to avoid that at all costs... but the only way I can think to prevent code injection attacks (is that the appropriate name?) is: Close the system: No user can define formulas, and If an admin needs to apply a custom formula, then (s)he would need to ask the system administrator to write, test and implement it. So, in short: Is there a way to give a little group of users (administrators) the freedom (and power) to define custom functions that would be applied under certain conditions? If there … -
How to create django model without primary key column and avoiding Id default column

Django FactoryBoy - random choice not working with LazyFunction
I'm building a number of tests for our django application and I'm using FactoryBoy The Profile model has a gender field which is defined as follows: class Profile(models.Model): GENDER_CHOICES = ( (u'm', _(u'Male')), (u'f', _(u'Female')), ) gender = models.CharField( max_length=2, choices=GENDER_CHOICES, verbose_name=_("Gender"), null=True, blank=True ) I wanted to randomize the value of this field in factory boy with the following line of code: gender = factory.LazyFunction(random.choice(['f', 'm'])) However, this throws a TypeError: 'str' object is not callable error Using an old blogpost I then tried the following solution, which worked: gender = factory.LazyAttribute(lambda x: random.choice(['f', 'm'])) This solved the problem, but its unclear to me why it did. The documentation for factory.LazyFunction states that: The LazyFunction is the simplest case where the value of an attribute does not depend on the object being built. It takes as argument a method to call (function, lambda…); that method should not take any argument, though keyword arguments are safe but unused, and return a value. It was my understanding that random.choice(['f', 'm']) constituted a method call and thus should work as I expected it to. But as it did not my understanding of LazyFunction is clearly flawed and I was hoping somebody could … -
